  When a user expands the Data field of a process instance
  within Process Inspector, the following error is displayed in
  a pop-up window:
  "CWTBG0019E: Unexpected exception during execution. Exception
  information: 'For input string: "null"'."
  The corresponding exception stack may be seen in the logs:

  ... 37 more
  The issue occurs due to a null process instance ID being used
  in a REST API request made by Process Inspector.
  The following HTTP URL request may be seen in the browser's
  web console or fiddle logs:
  https://<host>:<port>/rest/bpm/wle/v1/process/null
  The problem only occurs when the task is on an External
  Activity.
  

Problem conclusion

• A fix is available for IBM BPM v8.5.5.0.  The error no longer
  occurs as the proper process instance ID is now being passed.
