Hi - I'm really struggling with using the protobuf plugin, I'm getting a

Messages with StartGroup wire type fields are not supported

error. I get these two lines in the log - > 2025-12-09T175743.046300Z ERROR tokio-runtime-worker pact_protobuf_plugin:message decoder Was expecting String but received an unknown fixed 32 bit type > 2025-12-09T175743.046532Z ERROR tokio-runtime-worker pact_protobuf_plugin:message decoder Was expecting String but received an unknown 64 bit type The ComparisonResult is

I saw that Groups are not supported - is there anything I can do to avoid this? I have a feeling the groups are the registered and birth_date values, in the .proto file these are google.protobuf.Timestamp When I debug through, these 2 fields are FieldDescriptor.JavaType.MESSAGE

The gRPC plugin doesn't support group fields

TransformedUser.proto
