----------------------------------
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.
