Google/protobuf/wrappers.proto support is not implemented in K6

[zibul444]

Brief summary

I wrote my service, and decided to test it:

service TestService {

  rpc Foo(Request) returns (google.protobuf.BoolValue) {
  }

  rpc Bar(Request) returns (Response) {
  }

}

message Request {
}

message Response {
  bool value = 1;
}

console.info("GRPC response code: " + response.status + ", response body: " + JSON.stringify(response.message));
console.info(`${subMethod} Response: ${JSON.stringify(response)}`)

INFO[0000] GRPC response code: 0, response body: {}      source=console
INFO[0000] Foo Response: {"message":{},"error":null,"headers":{"content-type":["application/grpc"]},"trailers":{},"status":0}  source=console
INFO[0000] GRPC response code: 0, response body: {"value":false}  source=console
INFO[0000] Bar Response: {"message":{"value":false},"error":null,"headers":{"content-type":["application/grpc"]},"trailers":{},"status":0}  source=console

Actually, this is the problem. Google/protobuf/wrappers.proto support is not implemented in K6

k6 version

v0.44.1

OS

all

Docker version and image (if applicable)

No response

Steps to reproduce the problem

rpc Foo(Request) returns (google.protobuf.BoolValue) {
  }

client.connect(api_url, {
    plaintext: true,
    reflect: true,
    timeout: params.timeout,
    maxReceiveSize: 300000
});
response = client.invoke(method, body, params)

console.info(`${subMethod} Response: ${JSON.stringify(response)}`);

Expected behaviour

INFO[0000] Bar Response: {"message":"false","error":null,"headers":{"content-type":["application/grpc"]},"trailers":{},"status":0} source=console

Actual behaviour

INFO[0000] Bar Response: {"message":"","error":null,"headers":{"content-type":["application/grpc"]},"trailers":{},"status":0} source=console
