> [FLIP-401|https://cwiki.apache.org/confluence/display/FLINK/FLIP-401%3A+REST+API+JSON+response+deserialization+unknown+field+tolerance]
> and FLINK-33268 mentioned, when an old version REST client receives response
> from a new version REST server, with strict JSON mapper, the client will
> throw exceptions on newly added fields, which is not convenient for
> situations where a centralized client deals with REST servers of different
> versions (e.g. k8s operator).
> But this incompatibility can also happens at server side, when a new version
> REST client sends requests to an old version REST server with additional
> fields. Making server flexible with unknown fields can save clients from
> backward compatibility code.
