Description

I have a flow in the registry where the 'autoTerminatedRelationships' for a processor are null. This causes NiFi to throw a NPE, which prevents me from getting to the UI. NiFi should avoid throwing the NPE, should provide better logging to indicate where the problem is (which Process Group), and should in most cases just log errors and transition a PG's Versioned Flow State to a state of SYNC_FAILURE with an appropriate error instead of throwing Exceptions that could prevent the UI from responding
