CUCM Users Connector - Null Reference Exception when exporting without groupNames field.

Richard Green 11 years ago in UNIFYBroker/Cisco Unified Communications Manager • updated by anonymous 9 years ago • 4

Hi Guys,

While testing last night, I encountered an error with the CUCM User connector.
If an export is made without the 'groupNames' field present, it throws a null reference exception.

If the field is present, the export run's without error and behaves as expected.

I expect this will be straightforward to track down, but regardless, here is the full stack trace from the IDB log:

Save entities to connector failed.
Save entities [Count:1] to connector CUCM User Connector failed with reason Object reference not set to an instance of an object.. Duration: 00:00:00.3788820

Let me know if I can provide further assistance.

Try v4.0.0.2: https://unifysolutions.jira.com/wiki/display/SUBIDBUCM/Downloads

Confirming this has fixed the error when exporting with no groupNames attribute present.
I will need to test another export with this attribute present to confirm the fix.

Close upon confirmation.
