Troubleshoot Workflow DCN Failures

Problem: An error code and message may be returned to the calling party when a workflow data change notification (DCN) fails.

Solution: Resolve the problem and resend the workflow DCN. Unwired Server failures and errors include:

Unwired Server down – HTTP 400 is returned to the calling party
Missing DCN parameter, such as cmd=wf – HTTP 500 is returned to the calling party

The workflow DCN message is sent to a non-existent user – this error message is returned to the calling party:

xmlResponse: {"id":"000000392902","success":false,
"statusMessage":"no workflow message is sent because no 
device is found to send the notification","result":[]}
