java.lang.NullPointerException triggered by ApplicationSetup OOTB activity
Hi, we have observed in our log files, that lot of EXCP0001 alerts are being logged .
On further analysis we have found out that a Null pointer exception is occurring from ApplicationSetup OOTB activity .
Can anyone help me out when this "ApplicationSetup" rule will be triggered and what could be the reason behind Null pointer exception. Thank you!! PFB sample log

@AkhilReddyP16751743Looking at the history tab of the rule, there are two scenario's:
- Invoked Application/Access Group configuration when a thread is spawned with an application -> launching a portal should trigger this
- or an application is switched on a thread -> switching applications should trigger this
So if you trace the ApplicationSetup activity (possibly a remote trace when switching applications, not sure how the trace handles this from the same requestor), I would start with verifying if and which one of these two log the NullPointerExceptione error. The stack trace indicates an issue with the java code being executed, so you could perhaps add some log statements to the java step.
If you have some sort of Sandbox application available or are willing to test with a Pega Platform access group, do see if the same errors are logged when replaying the scenario's. That will make sure that it's an issue with the local system / configuration instead of a platform issue.

Hi @BasG0629, Thank you fro replying to the post. I have already tried the approach you have mentioned .I have added some log steps in Java code and replicated the scenario but there were no Nullpointerexceptions caught in our non-prod environments.

@AkhilReddyP16751743In that case, I would usually log a SR with the info you've already provided so that a SME can help you debug the issue / shed light on why the setShrinkJavaScriptEnabled function is referred to in the stack trace. Could be a model operator setting or a production level that prevents succesful execution, but perhaps this is a known issue as well...
