I noticed similar error when I have my flow using older version of a custom
nar and when I deployed new version of nar with package refactoring.
My workaround to bring the server back is to redeploy old nar, start nifi
and delete the flow then recreate the flow after deploying refactored nar.
Nifi should start even a nar file is replaced or removed.
