James, Can you please share the full log entry for that failure. It is possible the processor is not catching the exception properly and routing the data to failure. It might simply be letting the exception loose thus the framework detects the issue and rollsback the session and yields the processor.
Likely an easy thing to fix in the processor but please do share the full nifi-app.log entry for this. Thanks Joe On Wed, Dec 14, 2016 at 10:47 AM, James McMahon <[email protected]> wrote: > Hello.
