----------------------------
Summary: NullPointerException when changing version of process
group with versioned child process group
Key: NIFI-7556
URL: https://issues.apache.org/jira/browse/NIFI-7556
Project: Apache NiFi
Issue Type: Bug
Components: Flow Versioning
Affects Versions: 1.11.4, 1.11.3
Reporter: Exidex
After adding versioned child process group to process group and pushing it to
nifi registry I am unable to change the version of other instances of the same
process group because of NullPointerException. Removing child process group
resolved the issue.
