JMeter's HTTP Request file throws 404 error - jmeter

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.

Jmeter Favicon how to exclude?

I did record with blazemeter a test.
Now it is giving me this error The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. at the favicons.
Is there a way to exlude it from the jmeter script?
Or what is another solution?
If the favicon is a separate HTTP Request sampler - add a Response Assertion to it, tick Ignore status box and set the expected response code to the actual one
If the favicon comes with the "embedded resources" you could add the next line to user.properties file:
httpsampler.ignore_failed_embedded_resources=true
and after JMeter restart the problem should go away

Using JMeter 5.4.1 recording .Net application gets either wrong response or Error response Code: 500

Using:
JMeter version 5.4.1
Browsers:
MS Edge 94.0
Google Chrome: 94.0
FireFox: 92.0.1
Using JMeter to record .Net application. 90% of the recording was perfectly fine. no page crashed and received the response correctly. Except, when I made any requests that related to permission.aspx or permission.asp page I got error message have shown below or wrong response content displayed on the page.
I did try to change the record type from httpclient4 to Java but it didn't help.
Also Error log from JMeter log showed: Cause: java.io.IOExeption: Server returned HTTP response code: 500 for URL: https://xxxx.xx.xx.com/
USERID:
ASP.Net EXCEPTION:
StatusCode:
200
Error Message:
Exception of type 'System.Web.HttpUnhandledException' was thrown.
Inner Exception:
System.NullReferenceException: Object reference not set to an instance of an object.
Your question provide sufficient level of details so I doubt you will get a comprehensive answer, it looks like JMeter isn't capable of handling some specific setup of your application.
In order to get more information you could:
Increase logging level verbosity for JMeter's HTTP(S) Test Script Recorder by adding the next line to log4j2.xml file:
<Logger name="org.apache.jmeter.protocol.http.proxy" level="debug" />
then inspect jmeter.log file for any suspicious entries
Check your application logs as HTTP 5xx errors are server-side errors so most probably the reason can be found there
You might also want to try out an alternative way of recording a JMeter test: JMeter Chrome Extension which is kind of less "invasive" and "alien" to the browser than JMeter's proxy server.

JMeter HTTP Request shows a second failed result of a wrong URL

My results tree shows a separate status for a URL connection I have absolutely no idea where it might come from:
The first result with the -0 at the end is that of the request I send willingly. The other connection with the -1 comes out of the void.
In the response body I can see that JMeter fails while trying to resolve the DNS name:
java.net.UnknownHostException: aida.xyz.removed
at java.base/java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)
at java.base/java.net.InetAddress$PlatformNameService.lookupAllHostAddr(Unknown Source)
This is my definition of the HTTP Request:
As you can see this goes to a totally different host and protocol (http instead of https).
I checked the defined csv, it does not contain the hostname "aid". Same goes for the JMX file and any environment variables set.
I am using Apache JMeter 5.0
After I read Ubiks answer I checked if there are any redirects in the first request. There are no redirects but in the content there are several script and img resources.
It looks like JMeter parses the first request for resources it has to download. But I didn't enable this setting / don't even know where to activate this.
I guess it’s either a redirect issued from response to the first request or because JMeter tries to download embedded resources.
Check the response of first request.
If the reason is that JMeter downloads (probably missing) resources, make sure you disable Retrieve All Embedded Resources in the Advanced tab.
The error you're getting indicates the problem with the system under test, JMeter cannot resolve an embedded resource - image, script, style, font, iframe, whatever.
You need to raise an issue as not available content is not good i.e. for SEO purposes, moreover it might be essential for your application functionality of LAF
If this is a known issue which is in process of fixing (or considered as won't fix) you can turn JMeter's check for embedded resources presence by adding the next line to user.properties file:
httpsampler.ignore_failed_embedded_resources=true
JMeter restart will be required to pick the property up.

Jmeter Uncaught exception: java.lang.NullPointerException

I am trying to record REST requests with "http(s) test script recorder". It's working properly and record the request until i keep "Capture HTTP Headers" checked. Since I want to keep header common with some variable throughout requests and wanted to put dynamic parameter I don't want http header to be recorded everytime.
To do so, I remove that checkbox "Capture HTTP Headers", now none of my requests are getting recorded. And application is throwing exception
I am using https://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.pdf to record the requests.
ERROR - jmeter.JMeter:
Uncaught exception: java.lang.NullPointerException

I logged the bug with jmeter issue tracker.
They have suggested a solution to recompile the source with these 2 file changes.

How to do error handling in 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.
