I was wondering why the resume function works if you navigate away from an upload but it does not work when you use the retry link.
I am using S3 uploader and here is my enabled setting
retry: {
enableAuto: true
},
resume: {
enabled: true
},
Now when I navigate away from the page during an upload, close the browser , then come back I can resume the upload by starting a new upload of the same file.
However, if I deliberately disable the network adapter and let it error, then turn the network back on , I would expect to be able to hit retry and it start from where it stopped. It does not, it starts back at the beginning.
Would someone please enlighten me?
Fine Uploader will always either resume or retry starting with the last failed chunk. My tests show that this is functioning correctly with Fine Uploader S3 5.0.8. If you are seeing something different, please open up a bug case with all of your code and a detailed description of the issue along with the reproduction steps in the Github project's issue tracker.

I'm using VueJS and Laravel for my project. This issue started to show lately and it shows even in the old git branches.
This error only shows in the Chrome browser.
I disabled all installed extensions in Chrome - works for me.
I have now clear console without errors.
In case you're an extension developer who googled your way here trying to stop causing this error:
The issue isn't CORB (as another answer here states) as blocked CORs manifest as warnings like -
Cross-Origin Read Blocking (CORB) blocked cross-origin response
https://www.example.com/example.html with MIME type text/html. See
https://www.chromestatus.com/feature/5629709824032768 for more
details.
The issue is most likely a mishandled async response to runtime.sendMessage. As MDN says:
To send an asynchronous response, there are two options:
return true from the event listener. This keeps the sendResponse
function valid after the listener returns, so you can call it later.
return a Promise from the event listener, and resolve
when you have the response (or reject it in case of an error).
When you send an async response but fail to use either of these mechanisms, the supplied sendResponse argument to sendMessage goes out of scope and the result is exactly as the error message says: your message port (the message-passing apparatus) is closed before the response was received.
Webextension-polyfill authors have already written about it in June 2018.
So bottom line, if you see your extension causing these errors - inspect closely all your onMessage listeners. Some of them probably need to start returning promises (marking them as async should be enough). [Thanks #vdegenne]
If you go to chrome://extensions/, you can just toggle each extension one at a time and see which one is actually triggering the issue.
Once you toggle the extension off, refresh the page where you are seeing the error and wiggle the mouse around, or click. Mouse actions are the things that are throwing errors.
So I was able to pinpoint which extension was actually causing the issue and disable it.
Post is rather old and not closely related to Chrome extensions development, but let it be here.
I had same problem when responding on message in callback. The solution is to return true in background message listener.
Here is simple example of background.js. It responses to any message from popup.js.
chrome.runtime.onMessage.addListener(function(rq, sender, sendResponse) {
// setTimeout to simulate any callback (even from storage.sync)
setTimeout(function() {
sendResponse({status: true});
}, 1);
// return true; // uncomment this line to fix error
});
Here is popup.js, which sends message on popup. You'll get exceptions until you un-comment "return true" line in background.js file.
document.addEventListener("DOMContentLoaded", () => {
chrome.extension.sendMessage({action: "ping"}, function(resp) {
console.log(JSON.stringify(resp));
});
});
manifest.json, just in case :) Pay attention on alarm permissions section!
{
"name": "TestMessages",
"version": "0.1.0",
"manifest_version": 2,
"browser_action": {
"default_popup": "src/popup.html"
},
"background": {
"scripts": ["src/background.js"],
"persistent": false
},
"permissions": [
"alarms"
]
}
To me i was using a VPN extension called
Free VPN for Chrome - VPN Proxy VeePN It was causing the error after disabling it only ... the error disappeared
This error is generally caused by one of your Chrome extensions.
I recommend installing this One-Click Extension Disabler, I use it with the keyboard shortcut COMMAND (⌘) + SHIFT (⇧) + D — to quickly disable/enable all my extensions.
Once the extensions are disabled this error message should go away.
Peace! ✌️
If error reason is extension use incognito Ctrl+Shift+N. In incognito mode Chrome does not have extensions.
UPD. If you need some extension in incognito mode e.g. ReduxDevTools or any other, in extension settings turn on "Allow in incognito"
Make sure you are using the correct syntax.
We should use the sendMessage() method after listening it.
Here is a simple example of contentScript.js It sendRequest to app.js.
contentScript.js
chrome.extension.sendRequest({
title: 'giveSomeTitle', params: paramsToSend
}, function(result) {
// Do Some action
});
app.js
chrome.extension.onRequest.addListener( function(message, sender,
sendResponse) {
if(message.title === 'giveSomeTitle'){
// Do some action with message.params
sendResponse(true);
}
});
For those coming here to debug this error in Chrome 73, one possibility is because Chrome 73 onwards disallows cross-origin requests in content scripts.

https://www.chromium.org/Home/chromium-security/extension-content-script-fetches
This affects many Chrome extension authors, who now need to scramble to fix the extensions because Chrome thinks "Our data shows that most extensions will not be affected by this change."
(it has nothing to do with your app code)
UPDATE: I fixed the CORs issue but I still see this error. I suspect it is Chrome's fault here.
In my case it was a breakpoint set in my own page source. If I removed or disabled the breakpoint then the error would clear up.
The breakpoint was in a moderately complex chunk of rendering code. Other breakpoints in different parts of the page had no such effect. I was not able to work out a simple test case that always trigger this error.
I suggest you first disable all the extensions then one by one enable them until you find the one that has caused the issue in my case Natural Reader Text to Speech was causing this error so I disabled it. nothing to do with Cross-Origin Read Blocking (CORB) unless the error mention Cross-Origin then further up the tread it is worthwhile trying that approach.
I faced the same error in my react project running.
That error coming from my chrome
IObit Surfing Protection
2.2.7
extensions. That extension off my error was solved.
If you face same like that error, 1st turn off your chrome ad blocker or any other extensions while running.
Late here but in my case it was Kaspersky Cloud Protection Extension. I disabled it. It worked all good.
The cause of this issue is related to one of your chrome extensions, not CORS or CORB. To fix that you can turn off each and every chrome extension you installed.
Norton Safe Web extension for chrome is throwing this error message for me. After I disabled this extension, the error message disappeared.
Just cleaning site cookies worked here.
In my case i had to switch off "Adblock extension" from chrome.
I'm doing a tiny offline-able web app / PWA. It's meant to be opened from a home screen icon and mimic a regular app by loading entirely from a cache when offline.
The app is written using Vue and to accomplish the above I'm just using their PWA template and whatever it generates. To the best of my knowledge what this does is set up workbox using the GenerateSW plugin to precache everything in the Webpack build, and registers it using register-service-worker. That is, I have fairly little control out of the box over the fine details, it's meant to be a turnkey solution.
That said, I'm not sure how to actually load a new build of the application when it's available. The above can detect this - the generated SW registration file with my changes looks like this:
import debug from 'debug';
import { register } from 'register-service-worker';
if (process.env.NODE_ENV === 'production') {
register(`${process.env.BASE_URL}service-worker.js`, {
ready(...args) {
log('App is being served from cache by a service worker.\n', ...args);
},
cached(...args) {
log('Content has been cached for offline use.', ...args);
},
updated(...args) {
log('New content is available; please refresh.', ...args);
},
offline(...args) {
log('No internet connection found. App is running in offline mode.', ...args);
},
error(error, ...args) {
log('Error during service worker registration:', error, ...args);
}
});
}
When I make a new build of the application, and I refresh the app in a browser, the updated() callback is executed, but nothing else is done. When I tried adding:
window.location.reload(true);
which should be a forced refresh, I just get a refresh loop. I'm assuming this is because the service worker cache is completely independent from the browser cache and unaffected by things like the above or Ctrl+F5. (Which makes the "please refresh" rather misleading.)
Since this is going to mimic a native app, and it's supposed to be a simple line-of-business tool, I don't really need to do anything more complicated than immediately reload to the new version of the app when an update is available. How can I achieve this?
Okay so the behaviour I've observed is that the update does happen automatically, it's just not obvious as to what the exact sequence of events is. I'll try to describe my best understanding of how the generated service worker works in the installed PWA scenario. I'll speak in terms of "app versions" for simplicity, because the mental model behind this is closer to how apps, not webpages work:
You deploy v1 of your application to a server, install / precache it on a device, and run it for the first time.
When you suspend and resume your app, it does not hit your servers at all.
The app will check for an update when it's either cold-started, or you reload the page, i.e. using the pull down gesture on Android.
(Possibly also periodically as the cached version goes stale, but I haven't checked this.)
Say you've deployed v2 of your app in the meantime. Reloading an instance of v1 of the app will find this update, and precache it.
(One reason why prompting the user to reload doesn't seem to make sense. Whatever the reloading is meant to accomplish has already happened.)
Reloading an instance of v1 again does absolutely nothing. The app remains running between reloads, and you'll just get v1 afterwards.
(Reason number two why prompting the user to reload is pointless - it's not what causes a new version of an app to load.)
However, next time you cold start your app - e.g. nuke it from the task switcher and reopen - v2 of your app will be loaded and I'm guessing v1 will get cleaned out. That is, your app must fully shut down so an update will load.
In short, for an application to be updated from v1 to v2, the following steps need to occur:
Deploy v2 to server
Refresh instance of v1 on device, or shut down and reopen the app.
Shut down and reopen the app (again).
I am fairly new with using Selenium in my Ruby script. Basically my script will make a get request to some url and log in. However my script is failing to send the email and log in automatically due to the Google Chrome pop up about insecure content blocked since one of the images on the page is using http and not https.
I was able to run the script successfully months ago however just recently when trying again, it is unable to proceed with logging in so I dont know why it stopped working all of a sudden.
The error that I see in terminal is this. In irb, I can go through each line of code successfully including using Selenium's "send_keys" and "click" to automatically sign in.

I tried searching for some solution but have been unsuccessful. There has been some variations of responses to similar problem but not too much luck with getting it to work.
Any feedback on how to fix would be appreciated.
start Chrome manualy and disable the warning - https://www.thewindowsclub.com/disable-insecure-content-warning-chrome
and use the set browser profile, there is my setup:
#BeforeClass
public static void setUpClass() {
System.setProperty("webdriver.chrome.driver", "C:\\Users\\pburgr\\Desktop\\chromedriver\\chromedriver.exe");
ChromeOptions options = new ChromeOptions();
options.addArguments("user-data-dir=C:\\Users\\pburgr\\AppData\\Local\\Google\\Chrome\\User Data");
driver = new ChromeDriver(options);
driver.manage().window().maximize();}
I'm new to cypress and love the way it is architected. However, I seem to have run into a problem early on for a very simple thing that I'm trying to do.
My workflow is:
1) Visit the site
2) Enter username and password
3) On the next screen, type a number and press submit,
4) On the next screen, select a value from a dropdown and press enter.
5) I get to the landing page of my website.
Cypress works totally fine till step 4). It seems to stall at step 5. The test runner suddenly stalls and without warning or error, shows
"Whoops, there is no test to run."
From here, when I click the "View All Tests" button, it takes me to the runner tool. There I see the indication that something is still running in the background. I tried waiting for more than 10 minutes but nothing happens until I click on the "Stop" action.
How do I debug this? Can I see what is happening via any log etc?
There could even be something wrong with my website as well, but without any log information, I'm unable to proceed further. Any help is appreciated.
To provide more context, I don't think this is a timeout based issue as if that were the case, cypress did report to me about this and stopped. I then increased the timeout.
My spec file
describe('My first test', function() {
it('Visits home page', function() {
cy.visit('https://mywebsite.com:5800', {timeout: 400000}, {pageLoadTimeout: 400000}, {defaultCommandTimeout: 400000})
cy.get('#USERNAME').type('myusername')
cy.get('#PASSWORD').type('mypassword')
cy.get('#loginbutton').click()
cy.get('#SOMELEMENT_WHERE_I_TYPE_A_UNIQUE_NUMBER').type('8056')
cy.get('#loginbutton').click()
cy.get('#loginbutton').click()
})
})
Thanks.
If you run DEBUG=cypress:* cypress open from the terminal when initially opening Cypress, there will be more debug log information printed there while you run your tests.
Also, it's always a good idea to search the issues for the project to see if anyone else has had this happen.
For some reason, the Cypress automation gets into a state where it thinks that you have no spec file. All Cypress does to determine this is to see if there is a location.hash defined on the main window -> where it usually says https://localhost:2020/__/#tests/integration/my_spec.js.
Likely this is due to security mechanisms in the app that prevent your application from being run within an iframe (which is how Cypress runs all applications under test). Maybe in your application code it is something like:
if (top !== self) {
top.location.href = self.location.href;
}
You can simply disable these checks while testing or in Cypress you can add to your test file (or a support file to have it work on every test file):
Cypress.on('window:before:load', (win) => {
Object.defineProperty(win, 'self', {
get: () => {
return window.top
}
})
})
I had the same issue. Usually this is related to the page moving out of the parent and can be solved by invoking the attribute and changing it to the current page.
cy.get('.approved-content .no-auto-submit').invoke('attr', 'target', '_self');
I am running several tests with WebDriver and Firefox.
I'm running into a problem with the following command:
WebDriver.get(www.google.com);
With this command, WebDriver blocks till the onload event is fired. While this can normally takes seconds, it can take hours on websites which never finish loading.
What I'd like to do is stop loading the page after a certain timeout, somehow simulating Firefox's stop button.
I first tried execute the following JS code every time that I tried loading a page:
var loadTimeout=setTimeout(\"window.stop();\", 10000);
Unfortunately this doesn't work, probably because :
Because of the order in which scripts are loaded, the stop() method cannot stop the document in which it is contained from loading 1
UPDATE 1: I tried to use SquidProxy in order to add connect and request timeouts, but the problem persisted.
One weird thing that I found today is that one web site that never stopped loading on my machine (FF3.6 - 4.0 and Mac Os 10.6.7) loaded normally on other browsers and/or computers.
UPDATE 2: The problem apparently can be solved by telling Firefox not to load images. hopefully, everything will work after that...
I wish WebDriver had a better Chrome driver in order to use it. Firefox is disappointing me every day!
UPDATE 3: Selenium 2.9 added a new feature to handle cases where the driver appears to hang. This can be used with FirefoxProfile as follows:
FirefoxProfile firefoxProfile = new ProfilesIni().getProfile("web");
firefoxProfile.setPreference("webdriver.load.strategy", "fast");
I'll post whether this works after I try it.
UPDATE 4: at the end none of the above methods worked. I end up "killing" the threads that are taking to long to finish. I am planing to try Ghostdriver which is a Remote WebDriver that uses PhantomJS as back-end. PhantomJS is a headless WebKit scriptable, so i expect not to have the problems of a real browser such as firefox. For people that are not obligate to use firefox(crawling purposes) i will update with the results
UPDATE 5: Time for an update. Using for 5 months the ghostdriver 1.1 instead FirefoxDriver i can say that i am really happy with his performance and stability. I got some cases where we have not the appropriate behaviour but looks like in general ghostdriver is stable enough. So if you need, like me, a browser for crawling/web scraping purposes i recomend you use ghostdriver instead firefox and xvfb which will give you several headaches...
I was able to get around this doing a few things.
First, set a timeout for the webdriver. E.g.,
WebDriver wd;
... initialize wd ...
wd.manage().timeouts().pageLoadTimeout(5000, TimeUnit.MILLISECONDS);
Second, when doing your get, wrap it around a TimeoutException. (I added a UnhandledAlertException catch there just for good measure.) E.g.,
for (int i = 0; i < 10; i++) {
try {
wd.get(url);
break;
} catch (org.openqa.selenium.TimeoutException te) {
((JavascriptExecutor)wd).executeScript("window.stop();");
} catch (UnhandledAlertException uae) {
Alert alert = wd.switchTo().alert();
alert.accept();
}
}
This basically tries to load the page, but if it times out, it forces the page to stop loading via javascript, then tries to get the page again. It might not help in your case, but it definitely helped in mine, particularly when doing a webdriver's getCurrentUrl() command, which can also take too long, have an alert, and require the page to stop loading before you get the url.
I've run into the same problem, and there's no general solution it seems. There is, however, a bug about it in their bug tracking system which you could 'star' to vote for it.
http://code.google.com/p/selenium/issues/detail?id=687
One of the comments on that bug has a workaround which may work for you - Basically, it creates a separate thread which waits for the required time, and then tries to simulate pressing escape in the browser, but that requires the browser window to be frontmost, which may be a problem.
http://code.google.com/p/selenium/issues/detail?id=687#c4
My solution is to use this class:
WebDriverBackedSelenium;
//When creating a new browser:
WebDriver driver = _initBrowser(); //Just returns firefox WebDriver
WebDriverBackedSelenium backedSelenuium =
new WebDriverBackedSelenium(driver,"about:blank");
//This code has to be put where a TimeOut is detected
//I use ExecutorService and Future<?> Object
void onTimeOut()
{
backedSelenuium.runScript("window.stop();");
}
It was a really tedious issue to solve. However, I am wondering why people are complicating it. I just did the following and the problem got resolved (perhaps got supported recently):
driver= webdriver.Firefox()
driver.set_page_load_timeout(5)
driver.get('somewebpage')
It worked for me using Firefox driver (and Chrome driver as well).
One weird thing that i found today is that one web site that never stop loading on my machine (FF3.6 - 4.0 and Mac Os 10.6.7), is stop loading NORMALy in Chrome in my machine and also in another Mac Os and Windows machines of some colleague of mine!
I think the problem is closely related to Firefox bugs. See this blog post for details. Maybe upgrade of FireFox to the latest version will solve your problem. Anyway I wish to see Selenium update that simulates the "stop" button...
Basically I set the browser timeout lower than my selenium hub, and then catch the error. And then stop the browser from loading, then continue the test.
webdriver.manage().timeouts().pageLoadTimeout(55000);
function handleError(err){
console.log(err.stack);
};
return webdriver.get(url).then(null,handleError).then(function () {
return webdriver.executeScript("return window.stop()");
});
Well , the following concept worked with me on Chrome , try the same:
1) Navigate to "about:blank"
2) get element "body"
3) on the elemënt , just Send Keys Ësc
Just in case someone else might be stuck with the same forever loading annoyance, you can use simple add-ons such as Killspinners for Firefox to do the job effortlessly.
Edit : This solution doesn't work if javascript is the problem. Then you could go for a Greasemonkey script such as :
// ==UserScript==
// #name auto kill
// #namespace default
// #description auto kill
// #include *
// #version 1
// #grant none
// ==/UserScript==
function sleep1() {
window.stop();
setTimeout(sleep1, 1500);
}
setTimeout(sleep1, 5000);
