JR52504: COACHUNEXPECTEDFAILUREEXCEPTION OCCURS WHEN STARTING A SERVICE TASK CAUSED BY AN UNRESOLVED REFERENCE IN A PROCESS MODEL

7.5.1.2-WS-BPM-IFJR52504
Version 8.5 Refresh Pack 7 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• When you start a service task  by using the REST API the
  response cannot be created because there is an unresolved
  reference in the process model. As a result, you see the
  CoachUnexpectedFailureException. This exception causes the
  start of the service task to fail and the client to get a
  response with status code 500 (internal server error). In the
  SystemOut.log file, you see an exception that is similar to the
  following exception:
  
  00000047 RestHelper 3 Encountered exception has message:
  com.ibm.bpm.wle.api.CoachUnexpectedFailureException: CWTBG0061E:
  Unexpected failure occurred while processing the coach xml:
  'com.lombardisoftware.client.delegate.BusinessDelegateException:
  Service with ID TWProcess.3e2cabaf-b1b9-4d1e-a60d-586b159d1844
  not found.'
  

Local fix

Problem summary

• Because there are unresolved references in the IBM BPM model
  (the code that assembles the result of the start service REST
  API) an exception is thrown when the reference is resolved. As a
  result, the start of the task fails and the start task REST API
  returns a status code 500 (internal server error).
  

Problem conclusion

• A fix is/will be available for IBM BPM V7.5.1.2 that can deal
  with unresolved references when assembling the result for the
  start task REST API.
