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.
