Hi,
Thanks for posting on PSC.
I could similar kind of error reported earlier,
There could be multiple reasons, I have tried researching with "Problem during method invocation (doPost)"
- Problem during method invocation(doPost) Null Pointer Exception
- After login to PRPC (Problem during method invocation(doPost))
Suggestion:-
- Tried clearing caches
- Clean restart the server
Hope it helps, kindly acknowledge by marking this reply as answered/helpful for larger Pega audience.
Regards,
Asif
