Current Behavior

Problem

The inner struct object has not been parsed correctly. and is empty when using grpc-transcode plugin.

details

I have a grpc serivce with has below definition:

--- the request part
message RawRequest {
  google.protobuf.Struct reqdata = 1;
  string type = 2;
  string serviceurl = 3;
  string source = 4;
  int32 page = 5;
  int32 size = 6;
}

and I try to send a post request in postman with below request args:

{
    "type":"7",
    "serviceurl" :"xxxx",
    "reqdata" :{
        "key":"yyyy",
        "key_type":"zzzz",
        "model":"tttt"
    },
    "source":"3"
}

and When I checking the logs, I found the reqdata object is empty (not null).

Expected Behavior

The struct object should has data.

Error Logs

Steps to Reproduce

1. Create a routing from rest to grpc with grpc transcode.
2. and checking whether the grpc service side can receive the correct data.
