Description

The ObjectMapper used by Jersey is configured in ObjectMapperResolver and does not specify any configuration related to unknown fields, so the default is to fail.

This can be problematic when trying to import a flow definition that may have been produced with a newer NiFi version than the current one, and therefore has new fields.

This works when we import from registry because the registry client uses a different ObjectMapper, and the same for when using the UI to create a new process group from a file, but it fails using the process group replacement REST API.
