Answer
Deserialization can fail unless configured to ignore unknown properties.
If JSON contains fields not present in your Java class, deserialization throws an exception unless FAIL_ON_UNKNOWN_PROPERTIES is false. For example, if a 'Product' class lacks a 'category' field present in the JSON, it causes an error unless configured otherwise.
