Description

This can be recreated by adding a SplitText Processor to the canvas and then feeding it in a FlowFile that does not need to be split. In this case, a Provenance CLONE event is generated, and so is an ATTRIBUTES_MODIFIED event because after cloning the incoming FlowFile, we add attributes to the clone.

If we then attempt to query provenance for events generated by this Processor - or use the Provenance Reporting Task - we will get an error indicating that the Provenance Event could not be generated because it has no FlowFile UUID.
