Otto Fowler commented on NIFI-8625:
-----------------------------------
Thanks!
I just ran the template against main:
* change input directory
* remove filter
* input has 4 text files
* change log message ( success ) to logattributes
I am seeing exceptions in the nifi-app.log that are rolling back the session.
Can you see if you see those as well?
