Problem Statement:

When a multithreaded jmeter script is uploaded to LRE SaaS, if there are parameters being passed between different thread groups, LRE is unable to handle the same and throws 401 errors.

 Description:

When a multithreaded jmeter script is uploaded to LRE 24.1 SaaS, the script as per the new functionality in LRE, is being split into multiple scripts as per the thread group count. As per the jmeter documentation from LRE, when these split scripts are put together in the same scenario for concurrent runs, they should be able to run effectively like how we run the script separately without splitting it. However, when parameter exchange is involved between the multiple thread groups which is usually the case in many scripts, the parameter exchange is not happening for the some reason, and we get different errors (Mostly 401 in our case- as access tokens for login to application is involved)

Suggestion:

The same script is working as per requirement in previous versions (PC 12.63) where auto-split is not there and the script is handled as such. It would be better if similar approach be brought back, and we are able to have a jmeter script with parameter exchange between multiple thread groups be executed as such without issues.
