I'm using Python protobuf package version 5.38.3 for deserializing some packets and I need to check if the messages I deserialize are conformant or not to a specific protobuf message structure. For some checks I want to obtain the list of unknown fields.
This post points to an API UnknownFields() supported by messages, but when I call it in a deserialized message it raises NotImplementedError.
How can I get access to the list of unknown fields from a deserialized message in protobuf 5.28.3?

Python Breaking Change
In v25
message.UnknownFields()will be deprecated in pure Python and C++ extensions. It will be removed in v26. Use the newUnknownFieldSet(message)support in unknown_fields.py as a replacement.
You will want to update your code to use the new public API.
