> REST API returns plaintext errors with Content-Type of application/json
> -----------------------------------------------------------------------

> Key: NIFI-6307
> URL: https://issues.apache.org/jira/browse/NIFI-6307
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.8.0
> Reporter: Curtis W Ruck
> Priority: Major
>
> When using the REST API, if an error occurs, a text string is returned, but
> the response header Content-Type is 'application/json'
> GET controller/cluster returns "Only a node connected to a cluster can
> process the request." when disconnected
> Multiple endpoints return the text "This node is disconnected from its
> configured cluster. The requested change will only be allowed if the flag to
> acknowledge the disconnected node is set." when disconnected.
> Ideally the REST API should return errors in json i.e. \{"type": "error",
> "message": "This node is disconnected from its configured cluster. The
> requested change will only be allowed if the flag to acknowledge the
> disconnected node is set."} or set the content-type correctly.
