----------------------------------------
Summary: NullPointerException on missing FlowFile contents
Key: NIFI-14465
URL: https://issues.apache.org/jira/browse/NIFI-14465
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 2.2.0
Reporter: Andrea Di Stefano
Attachments: image (1).png, image (2).png, image (3).png
Hello,
we found an issue where a FlowFile had its content somehow deleted (we could
not find the contents in the content repository folder), but the FlowFile
itself was still in the queue of one processor and of course it could not be
processed.
The UI reported the following error:
EvaluateJsonPath[id=648a125b-c17f-3881-8282-1048ccb1c5d7] Processing halted:
yielding [1 sec]: java.lang.NullPointerException
I attached some screenshot of what we saw in the UI.
I think it can be replicated by queuing one file and manually delete the
contents from the content repository folder.
Shouldn't NiFi handle this situation gracefully (maybe just log a Warning and
automatically remove the file from the queue)? Or what could we do to avoid the
same issue in the future?
Thanks!
