Vitaly,
I believe that error is being generated by Jackson which handles the JSON
(de)serialization. Often times there is additional information that gets
logged to your logs/nifi-user.log. Check there to see if there is anything
helpful.
By any chance, are you attempting to pass the status back into the update
call? The entity object holds information about the component (the
configuration, the revision, status, permissions, etc). When performing an
update request you only need to pass in the revision (RevisionDTO) and the
configuration (ProcessorDTO). Check out the Developer Tools in your browser
to see various requests in action.
Hope this helps.
Matt
