> I created a process group via importing from the registry. I then made a few 
> modifications including settings properties and connecting some components. I 
> then attempted to revert my local changes so I could update the flow to a 
> newer version. When reverting the local changes, NiFi threw a NPE with the 
> following stack trace:
