Github user MikeThomsen commented on the issue: https://github.com/apache/nifi/pull/2517 @JohannesDaniel I didn't see a test that tests deep pagination. If you don't have one, please add one. You can just throw garbage data in there like random strings. Also, you should add at least one test that proves all of the declared attributes are written when they're expected to be available on output flowfiles.
