Question
java.lang.NullPointerException when creating a new class
We are facing a issue that we can't create a class on Base ruleset.
When creating a class, setting detail information and clicking "Save", an error" java.lang.NullPointerException" occurs and we can't complete creating the class.
We need to resolve this issue as soon as possible for delivery.
Would you please let us know resolutions regarding this issue?
Please attach the tracer and log files while reproducing the issue
Thank you for your cooperation.
I attached the tracer and log files.
Would you please check them?
Hello,
Thanks for sharing the requested information. Information in the Pega log doesn't have much useful information apart from the below NPE,
2019-03-06 10:19:19,131 [ttp-apr-8080-exec-31] [TABTHREAD5] [ ] [ GRPKessai:01.01.01] ( internal.mgmt.Executable) ERROR - Exception java.lang.NullPointerException
2019-03-06 10:19:19,131 [ttp-apr-8080-exec-31] [TABTHREAD5] [ ] [ GRPKessai:01.01.01] (Validate.Rule_Obj_Class.Action) ERROR santen- - Problem validating class Santen-FW-Base-Data-MyDivisionApplication java.lang.NullPointerException
But in the tracer log noticed that the Rule-Obj-Class.PreSave activity step 1 is failing to find an instance using Obj-Open-By-Handle with pzInsKey = RULE-OBJ-CLASS SANTEN-FW-BASE-DATA-MYDIVISIONAPPLICATION with the below error in line 119,
Unable to open an instance using the given inputs: RULE-OBJ-CLASS SANTEN-FW-BASE-DATA-MYDIVISIONAPPLICATION
The activity unable to open the Class record with the above pzInsKey and we don't have sufficient information regarding its failure to find the record in database. So probably you can try to enable the DB Query and DB Cache in your tracer settings to see why the system not able to open this record.
Hope this might help you to proceed further with your investigation.

Hi Mahesh,
I appreciate your help.
As a result of investigating this issue, I could create the class by setting my access role as Base class administrator.
Can you share the stack trace from the log file?
