How to get the exact guacd error code

[Abhishek627]

I want to get the exact error code or error message from underlying guacd code. How do I get it ?

This is my code right now.

        mux := http.NewServeMux()

	// prepare Websocket server
	wsSraServer := guac.NewWebsocketServer(cfg.wsDoConnect)
	mux.Handle("/test/ext/websocket-tunnel", wsSraServer)

	if cfg.httpTunnel == "enable" {
		// prepare HTTP server
		httpSraServlet := guac.NewServer(cfg.httpDoConnect)
		mux.Handle("/tunnel", httpSraServlet)
		mux.Handle("/test/ext/tunnel", httpSraServlet)
	}	

	//wsSraServer.OnConnectWs = cfg.OnConnectWs
	// wsSraServer.OnDisconnectWs = cfg.OnDisconnectWs
