Ryan created NIFI-13272:
---------------------------
Summary: 'Empty all queues' functionality throws a null pointer
when executed against an empty processor group.
Key: NIFI-13272
URL: https://issues.apache.org/jira/browse/NIFI-13272
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 1.26.0
Reporter: Ryan
I have recently upgraded from 1.23.2 to 1.25.0 and I have noticed an issue with
how the ‘Empty all queues’ functionality works.
If I create an empty process group and click ‘Empty all queues’ Nifi returns a
{{500 Internal Server Error}} with a response of '{{{}An unexpected error has
occurred. Please check the logs for additional details.'{}}} , when I look in
Nifi logs It throws a null pointer when creating a Drop Request.
