Github user MikeThomsen commented on the issue: https://github.com/apache/nifi/pull/2113 @JPercivall @mattyb149 That exception only happens for me when I stop the processor. It happens here: `` if (hitsFlowFiles.size() > 0) { session.transfer(hitsFlowFiles, REL_HITS); for (FlowFile ff : hitsFlowFiles) { session.getProvenanceReporter().send(ff, clientService.getTransitUrl(index, type)); } } `` On the provenance reporting line. Any ideas?
