workflow.20001.delta.repository

APAR status

• Closed as program error.

Error description

• The group details call (/rest/bpm/wle/v1/group/{groupNameOrID})
  returns HTTP 500, if the group id does not exist.
  
  The following exception occurs in the SystemOut:
  [2/12/20 11:04:14:017 CET] 000006c9 RestHelper    W
  java.lang.NullPointerException

  If a non-existing group name is entered, the call returns HTTP
  404 (NON EXISTENT) like expected.
  

Local fix

• The following alternatives can be used:
  a) group details with group name as argument
  /rest/bpm/wle/v1/group/{groupNameOrID}
  b) list all groups
  /rest/bpm/wle/v1/groups
  

Problem summary

• The response of HTTP Status 500 (internal server) is returned
  because calling the GET /rest/bpm/wle/v1/group/{groupNameOrID}
  REST API with a group ID that doesn't exists results in a
  NullPointerException that is reported as an internal server
  error.
  

Problem conclusion

• A fix is available or will be available that prevents the
  NullPointerException to ensure a 404 NOT FOUND response code is
  returned.
  

Temporary fix
