Gamecordinator csgo send ECsgoGCMsg = 9156 but steam not respond anyhing

[VusalShahbazov]

Hello! I have trouble with GC
When i send this request

client.GC.Write(gamecoordinator.NewGCMsgProtobuf(
	730,
	uint32(protobuf.ECsgoGCMsg_k_EMsgGCCStrike15_v2_Client2GCEconPreviewDataBlockRequest),
	&payload,
))

I dont get any response from steam

I Register the handler for client.GC but nothing appear after my request

type Handler struct{}

func (g *Handler) HandleGCPacket(p *gamecoordinator.GCPacket) {
	fmt.Println("HandleGCPacket")
	if p.AppId == 730 {
		switch p.MsgType {
		case uint32(protobuf.ECsgoGCMsg_k_EMsgGCCStrike15_v2_Client2GCEconPreviewDataBlockResponse):
			var res protobuf.CMsgGCCStrike15V2_Client2GCEconPreviewDataBlockResponse
			err := proto.Unmarshal(p.Body, &res)
			if err != nil {
				panic(err)
			}

			fmt.Println( res.Iteminfo.GetPaintwear())
		}
	}
}

// ... 
client.GC.RegisterPacketHandler(&Handler{})

And please provide examples of GC usage

Hello! I'm not familiar with this library yet, but I'm dealing with the same problem. After connecting and successfully authenticating, you need to indicate to the client that you are in the game.

var appID uint64 = 730

gp := protobuf.CMsgClientGamesPlayed{GamesPlayed: []*protobuf.CMsgClientGamesPlayed_GamePlayed{{GameId: &appID}}}

client.Write(protocol.NewClientMsgProtobuf(steamlang.EMsg_ClientGamesPlayed, &gp))

After that, you can send messages to the gс by writing the running game id to the app_id field, and wait for a response
