1. Navigate to a deployed feed
2. Shut down NiFi
3. Choose Export from the Summary menu
Result: in Chrome no error is given, but the download file in download bar says "Error with Server".
Note: The zip download on the left is the result of choosing Export when Nifi is running.
Note: For some reason Chrome Developer Tools doesn't catch the call to the server to get the download. All the calls shown in the Network tab seem to be working and returing 200 code. But the NifiConnectionExceptionMapper is catching the ProcessinException from JerseyRestClient, I suspect we don't handle the error correctly with the requested content-type.
