How to do error handling in Jmeter - jmeter

I'm using Jmeter to do a load testing for a website.
JMeter does not show errors other than 404 errors.
How can I get the error messages in JMeter for the errors that occur for other cases?

By default, JMeter only flags typical HTTP error response codes, like 4XX and 5XX errors.
You should use Response Assertions on your HTTP samplers if you wish to have finer control over what is flagged as an error.

You can use 404 code as a success also. When you put your assertion with 404, there is a checkbox in the corner that says 'Ignore Status'. This will treat also 404 as a success.

One annoyance with this though seems to be that JMeter always treats a 404 as an error, when can be a valid response for some applications. So even if you make an assertion that a 404 response is OK, it will still show as an error.

IIS 10 Failed Request 500 - General_Request_Start Failed To Complete

I'm trying to understand why after deployment my server is returning 500 - Internal server error for a simple GET request that checks the server's status which is supposed to return 200 (when I run it locally with unit tests I wrote, it works fine). I retrieved the failed request log, but can't quite seem to understand what the problem is.
In several events the severity column shows: Failed To Complete
The Request summary shows:
These are the Errors and Warnings shown:
Does anyone know why I might be getting theses errors, or why I might be getting a 500 Internal Server error response?
I will add that I already have a GET request that is working:
https://myalertsserver.cloudapp.net/providers/management/alerts which returns 200.
and when I try:
https://myalertsserver.cloudapp.net/providers/status I get a 404 Error.
It seems to me like it has to do with something in the configuration, but I can't seem to understand what.
Thanks in advance.

express graphql always sends 500 Internal server error for any thrown error from resolver

I am using express graphql in my node app . and it graphql always sends 500 Internal server error for any thrown error from resolver. Please suggest any solution so i will get proper response and status code
The express-graphql sends the HTTP error 500 whenever detects there is no data returned. Definitely, in case of exception is thrown there won't be a returning data. Although it looks like an obvious bug the developers have their own opinion on that. They seemed to decide providing an option to disable the feature so that the server shouldn't set the 500 error. At least the open issue on that is still there.
Checking out the sources I've found these options to get around the problem:
To set any other response code than 200 (e.g. 299 (custom)) in your resolver.
To set the response code in your error formatting handler. This seems to be the most optimal solution.
Just to pick up some other library =)

Jmeter - Telling http request not to fail

While execution of negative TC (login with Invalid user), i need to login with invalid data, but not get marked the execution as failed in 'View Results Tree', coz this is expected behavior by the system.
I try changing parameters in .jmx file, but without any result.
Is this possible to be done, so my 'http request' wont be marked as Failed?
If the failure is being caused by receiving HTTP Response Code >= 400 you can add a Response Assertion as a child of the request which is not supposed to fail and tick Ignore Status box
Check out Response Assertions in JMeter 3.2 - New and Improved article for more information on defining custom pass/fail criteria with Response Assertion
If your request fails for any other reason - please clarify it so we could come up with the optimal solution. Be aware that you can mark the request as passed using JSR223 Listener and the following Groovy code:
prev.setSuccessful(true)
Well, you can use a single Response Assertion with only 'ignore status' option checked.

JMeter's HTTP Request file throws 404 error

JMeter HTTP Request - 404 ERROR
While I run my jmx file, It throws a 404 error for one of the HTTP Request file. Screen shot is given above.
Can anyone please suggest some solution for this issue.
There is an embedded resource call for the /favicon URL which is not found therefore the request fails.
You should raise an issue as HTTP 404 errors might cause SEO consequences so your site will rank lower
If you don't care about the embedded resources errors you can add the next line to user.properties file:
httpsampler.ignore_failed_embedded_resources=true
JMeter restart will be required to pick the property up.

4xx Response from server doesn't include JSON data

I've got a .NET MVC site that uses JSON to perform AJAX form Posts. If a validation error occurs (ie user misses a required field etc), then the server returns the validation errors in a JSON object and sets the HTTP status code of the response to something in the 400 range. On our local machines, this works absolutely fine.
However on our CI environment, it has suddenly stopped working, without any code changes. The response comes back from the server with the correct HTTP code, but the content is not the JSON our controller returns, but the standard .NET error page HTML, ie just the 11-byte 'Bad Request' response if the status code is 400.
The error code is correct for each validation error, so we are hitting the right controller/action, and the validation is working correctly, but for some reason our JSON is getting snipped out. Any ideas why this might be happening?
You are getting 400 code because your request syntax in not correct. Check if you have actually encode json data correctly or not.
