Error description

  • The "v1/process/<process-instance-id>?action=js" REST API might
    result in an Internal Server Error 500 if trace logging is
    enabled for the REST API. This REST API attempts to log the
    result of the expression evaluation if trace logging is enabled,
     and if the expression evaluates to the value "null", then a
    NullPointerException might occur on the server, which then
    results in the Internal Server Error 500 being returned to the
    REST API caller.
    The following NPE is logged in the SystemOut.log file:
    
    [7/14/14 11:12:32:314 CDT] 0000021d RestHelper 3 Encountered
    exception has message: CWTBG0019E: Unexpected exception during
    execution. Exception information: 'js'.
