I have been setting up some tests with Nightwatch. I ran the following basic test on their website.
module.exports = {
'Search on google': (browser) => {
browser
.url('http://www.google.com')
.waitForElementVisible('body', 1000)
.setValue('input[type=text]', 'nightwatch')
.waitForElementVisible('button[name=btnG]', 1000)
.click('button[name=btnG]')
.pause(1000)
.assert.containsText('#main', 'Night Watch')
.end()
},
after: (browser) => {
browser.end()
}
};
And got the following error:
Timed out while waiting for element <button[name=btnG]> to be visible for 1000 milliseconds. - expected "visible" but got: "not visible"
My first attempt at correcting was to change .waitForElementVisible('button[name=btnG]', 1000) to 10000 but still ended up getting Timed out while waiting for element <button[name=btnG]> to be visible for 10000 milliseconds. - expected "visible" but got: "not visible".
Inspecting the google search button showed me that the button name was actually btnK so I tested that but it didn't work either returning expected "visible" but got: "not found".
Very stumped and not sure where to go from here. Anyone have an idea?
Any chance you're running this on Chrome 65? A recent change essentially causes setValue to error out. Your Nightwatch test would then fail on the next step. The best solution is to update your Chromedriver to 2.36.
Please see the answers here: unknown error: call function result missing 'value' for Selenium Send Keys even after chromedriver upgrade
I was facing the same issue. I had installed ChromeDriver from NPM it was v2.45.. My Chrome version was v69. When I downloaded the chrome driver from this link- https://chromedriver.storage.googleapis.com/index.html?path=2.36/ and updated my nightwatch.json to point to this downloaded chrome driver version using server_path. This solved the issue.

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.chromestatus.com/feature/5629709824032768
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 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've sent this as an issue because I believed it was at least a documentation problem, but I was advised to sent as a question in here.
I'm using admin-on-rest which is working perfectly on Firefox, but not on other browsers.
I've done every step as the documentation suggests, got the newest version so far and tried to search in the opened issues and stack overflow for a similar problem.
It seems to be a problem with cross-browser implementation or documentation with admin-on-rest.
What is happening:
The main problem is that for some browsers, mainly Chrome, it works fine until I try to GET_ONE or UPDATE resource. It gets the correct response, tries to render and then gives an Element does not exist error, returning to previous page (LIST).
admin-on-rest Problem Video
Steps to reproduce:
I created a fake account so you could test it. If you wish sent me in private and I may share with you.
I open the LIST view for Scores, click in show:
Scores -> show (any element)
It gives Status code: 200 OK, it renders and fails, going back to the previous page.
Other information:
I'm using admin-on-rest with a custom restClient [ restClient={myApiRestClient('http://localhost:3000/v1', httpClient) ], which seems to be fine, seen that the request runs out ok.
Environment
Admin-on-rest version: "^1.3.2"
React version: "^15.6.2"
Browser: Chrome, Chromium and Opera
For GET_ONE you may be returning the data directly instead of {'data': your_data}.
Instead of:
{
'id': 3,
'name': 'xyz'
}
it has to be returned as
{
'data': {
'id': 3,
'name': 'xyz'
}
}
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);
