jMeter Cookie Manager doesn't store all cookies - cookies

After reading documentation and posts in Internet I still cannot solve the problem with Cookie Manager in jMeter.
I got sid ID in response header but it is not stored in my cookies manager.
Below are the screens of my test plan and response with connect.sid
Could you help to figure out what is wrong?
Response with cookie
Cookie is not stored

In order to be handled by JMeter (and web browsers as well) your cookie needs to be compliant with some policies i.e. domain and path should not clash with the current URL, expiration date should not be in the past (your cookie expiration date is 20:33, looking into the time at your machine you have 23:21), etc.
Also your set-cookie header name looks suspicious, I used to see it with first capital letters like Set-Cookie
Suggestions:
Try out different "Cookie Policy" options:
Add the next line to user.properties file (lives in JMeter's "bin" folder)
CookieManager.check.cookies=false
Points 2 and 3 don't help you can get some extra information by enabling debugging output by adding the next line to the aforementioned user.properties file:
log_level.jmeter.protocol.http.control=DEBUG
and look into jmeter.log file for anything connected with CookieManager, HC4CookieHandler or HC3CookieHandler
As a last resort you can always get any cookie value using Regular Expression Extractor, the relevant configuration would be something like:

500 internal server error instead of 302 redirect- JMeter

I'm trying to investigate the issue as I mentioned in the subject.
I login to the application and successfully able to land on the home page of my application through my JMeter code.
When I click on "user details" tab , I should be redirected 2 times.
Successfully able to redirect for the first time. For the second redirection I'm getting 500 error code instead of 302 again.
URL for "User details" is a plain URL, doesn't come with any need of correlation.
I have cookie manager with "standard"( tried all other options also on cookie manager)
I see that - cookie value SameSite=None; is also seen at request body along with other values only during the reply of my script(I do not see this in the recorded traffic/even if I cross verify using fiddler).
Would like to know if this can be a problematic. If so how can I remove this.
Try playing with Redirect Automatically and Follow Redirects boxes in the HTTP Request sampler
if it doesn't help - be aware that you can extract the redirect URL from the Location header using Regular Expression Extractor
If you think that the problem is with the cookie you can enable debug logging for the HTTP Cookie Manager by adding the next line to log4j2.xml file (lives in "bin" folder of your JMeter installation:
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
this way you will be able to see what's going on under the hood in jmeter.log file as it might be the case that the cookie is broken somehow (expired, wrong path, etc.)

How can I decode the http encrypted cookie in Jmeter

I am now using Jmeter to prepare a test plan for my web. The rough flow of the script is that I can check my profile after login. I tried to run my recorded script, and found that the cookie is encoded in http format which I don't want it to be.
Therefore, I would like to ask is there anyway so that I can have a not encrypted cookie value?
[I applied a cookie manager in the script.
The value of the cookie now is something like "%22mh8eIAH8rfsZsM3r%22".
The value that I want is something like "mh8eIAH8rfsZsM3r"]
%22 means " which is percent-encoded, if you want to decode it back - take a look at __urldecode() function:
In general you should not be recording any cookies, you need to add a HTTP Cookie Manager and JMeter will automatically extract incoming cookies from Set-Cookie response header and add them to the next request as Cookie header if domain and path match the ones in the cookie, it's not expired, etc
If you need to access the cookie value as a JMeter Variable the easiest way is adding the next line to user.properties file:
CookieManager.save.cookies=true
and upon JMeter restart you will be able to use the cookie value as ${COOKIE_your-cookie-name-here}

Jmeter - How to send Cookie with the http request inside in the Header manager (not Cookie manager)

For the purpose of my test, I need to send Cookie within the request like bellow.
If I try to do it with Header manager, cookies are ignored
I cant see them into the Request Headers where I need to see them.
Is there any way, how I can send Cokie into the reqest?
Note: Using Cokie managers is not working for me.
CookieManager.save.cookies=true
CookieManager.check.cookies=false
Are set up into the user.variables.
Using Jmeter 5.4.3
You're looking at wrong place, the cookies are displayed under Request -> Request Body tabs of the View Results Tree listener
So you might want to check your HTTP Cookie Manager setup, it might be the case it's "working". If it doesn't - there might be a problem with the cookies returned by your application, i.e. it's expired, domain mismatch, path mismatch, etc.
In that case you need to raise a bug for your application or change the implementation of the HTTP Cookie Manager to something less restrictive i.e. netscape
You can see what's going on under the hood with the cookies by increasing JMeter logging verbosity for the HTTP Cookie Manager.
Add the next line to log4j2.xml file
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
and upon JMeter restart re-run your test and take a look at jmeter.log file, you should see the incoming cookies and whether they're going to be added to the next request or not.

How to manage Cookies are required error page?

I am new to jmeter. I record my script using blazemeter chrome plugin. Now in login I am getting Cookies are required Cookies are disabled on your browser. please enable cookies and refresh this page I have set CookieManager.save.cookies=true but no luck .
As per JMeter project main page:
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
So if your page is using JavaScript in order to check user cookies there is no way to bypass this message, it means that you can just ignore it.
However if you cannot proceed further it means that JMeter doesn't send necessary Cookie header so make sure to add HTTP Cookie Manager to your test plan.
If you added the HTTP Cookie Manager but still seeing that the real browser sends cookies and JMeter doesn't (or sends partial) most probably it means that your server returns malformed or expired cookies and you need to raise a defect for your application.
And last but not the least, if you have to live with these malformed/broken cookies and still need to log in you can go for the following workarounds:
Change "Implementation" of the HTTP Cookie Manager to something less restrictive, i.e. netscape
Add the next line to user.properties file (lives in "bin" folder of your JMeter installation:
CookieManager.check.cookies=false
Increase JMeter logging verbosity for the HTTP Cookie Manager by adding the next line to log4j2.xml file:
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
this way you will be able to figure out what's wrong with the cookies
And last but not the least you can always manually extract cookies from the Set-Cookie response header using i.e. Regular Expression Extractor and again manually add them to the HTTP Cookie Manager or HTTP Header Manager

JMeter clear cookie after HTTP Request in same iteration

I am struggling with the cookies to clear after certain step. This is what I have in a sample test plan
enter image description here
enter image description here
enter image description here
enter image description here
I am getting a data from CSV file and then I have multiple cookies - which are location IDs which I need to pass for each row from CSV. I have tried using the Cookie Manager with option to clear iteration which works fine for next row from CSV but not to loop through cookie list defined in the user defined variable. I looked at this article
I have tried adding this code at the same level as the HTTP request but get an error
sampler.getCookieManager().clear() function should do the trick for you
Demo:
Given you're getting an NPE most probably something is wrong with your HTTP Cookie Manager configuration, you can try enabling debug logging for it to see if JMeter "complains" on anything and if it does - fix the HTTP Cookie Manager configuration accordingly.
In order to get extended debug information for the HTTP Cookie Manager add the next line to log4j2.xml file:
<Logger name="org.apache.jmeter.protocol.http.control.CookieManager" level="debug" />
JMeter restart will be required to pick the property up.
Anyone looking for the answer it was quite simple in my case. I just had to add the blank Cookie Manager
Header Cookies
Earlier I had these filled with the values which was causing some issues.
Now I have added the JSR223 PreProcessor with this code and it worked fine
import org.apache.jmeter.protocol.http.control.CookieManager;
import org.apache.jmeter.protocol.http.control.Cookie;
Cookie newCookie;
CookieManager manager = sampler.getCookieManager();
location = vars.get("locationID_"+ vars.get("counter"))
Cookie myCookie = new Cookie("location_ID", location, google.com"/",false , 0);
manager.add(myCookie);
