In between, also tried adding this configuration -
objectMapper.configure(DeserializationFeature.READ_UNKNOWN_ENUM_VALUES_AS_NULL,
true);
This resulted in the Unknown attribute key to be deserialiezed as null.
(i.e., instead of Test=No, it gets deserialized as null=No)
My intention is to ignore this attribute completely during deserialization.
Please let me know if that would be possible by any means.
Thanks!
