## What is the purpose of the change This PR makes REST server ignoring unknown fields when deserializing request body, which is helpful in some senarios where a centralized REST client of newer version (contains additional fields in request) communicates with REST servers of various versions, potentially an old version that doesn't recognize additional fields.
