I have seen this too, IIRC it is due to an out-of-date “revision” value in the PUT. Try getting the most recent revision number (GET /controller/revision) and putting that in the body of the PUT.
If you have already done that, the other thing I think that causes this response is the wrong mime type, should be "application/x-www-form-urlencoded”. Hope this helps!

I have a Nifi group of 2 processors and I can retrieve the json config for each of them . perfect ! But when I modify the json config ( Input Directory for my getfile processor instance) and use REST PUT API to update the proc config, I get back these messages : : HTTP status code : 409 : This NiFi instance has been updated by 'anonymous'. Please refresh to synchronize the view. And the config of the processor is not updated ( checking it with GUI, doing a manual refresh status and also a REST get) Any idea ? problem of user auth?
