Mark Payne commented on NIFI-2015:
----------------------------------
[~ch...@mcdermott.net] which processor is being used here? Is it a custom a
processor or one in the nifi codebase? The reason that I am asking is that this
stack trace seems to imply that there is a FlowFile created that has no 'uuid'
attribute. However, this is not supposed to be possible. Wondering if there's a
validation check that is not being performed somewhere, so I would like to be
able to look at what is happening here and see if there's some way to create a
FlowFile with no UUID.
