How do I get results from rpc calls?

[nteko]

I made "getgamelist" runtime module on Nakama server.

If I call the api, it does not return payload of the call.

Is there way to get it?

Thank you. and Here is the RPC call log.

I found out how to get a result from RPC calling.

You need to modify "nakama_websocket_client.dart" ( from line # 185 )

if (waitingFuture is Completer<rtpb.Match>) {
          return waitingFuture.complete(receivedEnvelope.match);
        } else if (waitingFuture is Completer<rtpb.MatchmakerTicket>) {
          return waitingFuture.complete(receivedEnvelope.matchmakerTicket);
        } else if (waitingFuture is Completer<rtpb.Status>) {
          return waitingFuture.complete(receivedEnvelope.status);
        } else if (waitingFuture is Completer<rtpb.Channel>) {
          return waitingFuture.complete(receivedEnvelope.channel);
        } else if (waitingFuture is Completer<rtpb.ChannelMessageAck>) {
          return waitingFuture.complete(receivedEnvelope.channelMessageAck);
        } else {
          return waitingFuture.complete();
        }

to this ------------------------------------------

if (waitingFuture is Completer<rtpb.Match>) {
          return waitingFuture.complete(receivedEnvelope.match);
        } else if (waitingFuture is Completer<rtpb.MatchmakerTicket>) {
          return waitingFuture.complete(receivedEnvelope.matchmakerTicket);
        } else if (waitingFuture is Completer<rtpb.Status>) {
          return waitingFuture.complete(receivedEnvelope.status);
        } else if (waitingFuture is Completer<rtpb.Channel>) {
          return waitingFuture.complete(receivedEnvelope.channel);
        } else if (waitingFuture is Completer<rtpb.ChannelMessageAck>) {
          return waitingFuture.complete(receivedEnvelope.channelMessageAck);
        **} else if (waitingFuture is Completer<Rpc>) {
          return waitingFuture.complete(receivedEnvelope.rpc);**
        } else {
          return waitingFuture.complete();
        }

Thank you.
