Start with the /api/dev/test request and the GenericService invocation shown in the error, then trace how the fastjson2 serialization setting is selected. Reproduce the proto request with Dubbo Admin 0.5.0 and verify the result against a provider using fastjson2; done means the test interface invokes the method without the missing-serialization-extension error.
