             Summary: Retrieving runtime manifest from REST API produces unexpected error when clustered
                 Key: NIFI-14006
                 URL: https://issues.apache.org/jira/browse/NIFI-14006
             Project: Apache NiFi
          Issue Type: Bug
    Affects Versions: 2.0.0
            Reporter: Bryan Bende
            Assignee: Bryan Bende


When calling /nifi-api/flow/runtime-manifest in a cluster, it produces a response with an unexpected error. The logs show an issue with trying to unmarshall a replicated response and expecting it to be JSON, but it is empty string.
