protobuf type int64 not match to response

[czyt]

define a service

// 测试信息
  rpc GetTest(google.protobuf.Empty) returns(TestReply){
    option (google.api.http) = {
      get: "/v1/test"
    };

proto type

message TestReply{
  int64  count = 1;
  message TestPayload{
    int32  age = 1;
    int32 height =2;
  }
  TestPayload payload = 2;
}

the logic at service

func (a TestService) GetTest(context.Context, *emptypb.Empty) (*v1.TestReply, error) {
	return &v1.TestReply{
		Count: 11,
		Payload: &v1.TestReply_TestPayload{
			Age:    22,
			Height: 111,
		},
	}, nil
}

and call from url /v1/test get response

{
    "count": "11",
    "payload": {
        "age": 22,
        "height": 111
    }
}{
    "count": 11,
    "payload": {
        "age": 22,
        "height": 111
    }
}

the count feild was not right,should be int64 rather than string,then I change the count type to int32

message TestReply{
  int32  count = 1;
  message TestPayload{
    int32  age = 1;
    int32 height =2;
  }
  TestPayload payload = 2;
}

response is return as expect

{
    "count": 11,
    "payload": {
        "age": 22,
        "height": 111
    }
}
