Night Gryphon commented on NIFI-7944:
-------------------------------------
[~markap14] it seems I have sort of this issue after importing flow from
registry when flow wascreated with revious version of NiFi. How did you fix
this issue to be able to start server?

> Key: NIFI-7944
> URL: https://issues.apache.org/jira/browse/NIFI-7944
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Reporter: Mark Payne
> Assignee: Mark Payne
> Priority: Major
> Fix For: 1.13.0
>
> Time Spent: 1h
> Remaining Estimate: 0h
>
> Consider a flow with a Process Group "A". Within Process Group A is a child
> Process Group, B. Process Group B has a Controller Service and has a
> Processor that references it.
> Save Process Group A into NiFi Registry.
> Import Process Group A into NiFi. Step into the Process Group and configure
> the child Process Group (Group B). Go to the Controller Services tab and
> configure the Controller Service. The service will not show the Processor as
> a Referencing component.
> This can result in a few different problems:
> * The Controller Service can be disabled while it's still being used.
> * If the Controller Service is enabled, along with all Referencing
> Components, those missing components won't show up.
> * The Controller Service can be deleted while it's still being referenced.
>
> This can lead to the following types of logs messages:
