Have you verified the Pega log? HTTP 500 errors are mostly the result of an error resulting in a stacktrace being logged, which in turn could explain the problem.

I have checked the pega logs but their its showing Null pointer exception and the Access Logs gives below mentioned


 


GET /prweb/mFW9vHBT7hxOijRsFawQ3gjssssss*/!STANDARD?pzPostData=1361226563 HTTP/1.1" 500 3560

A nullpointer exception can be anything. Did you verify the operator that you are using? Is it equipped with an accessgroup? Is the accessgroup selected? Can you login manually with that specific user?

The access group are fine the user can very well login manually to the pega application.

I added below code right after the ".baseUrl(testServerUrl)" and could confirm it worked correctly. .userAgentHeader("Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.149 Safari/537.36")
