----------------------------------------
Summary: Stateless NiFi NullPointerException on versioned PGs
Key: NIFI-12918
URL: https://issues.apache.org/jira/browse/NIFI-12918
Project: Apache NiFi
Issue Type: Bug
Reporter: Stephanie Ambrose
If you create a process group and commit that to version control, and then add
a sub-process group under that one which is also under a separate version
control, it will throw a NullPointerException.
