My bot stuck on answering

[Disinterpreter]

Hi! My bot stuck on answering. Lemme show the code

func main() {
	client := bot_auth.Auth()
	client.AddCustomServerRequestHandler(func(i interface{}) bool {
		switch msg := i.(type) {
		case *telegram.UpdatesObj:
			bText, err := json.Marshal(i)
			if err != nil {
				println(err.Error())
			}
			updates := MessageStruct{}

			json.Unmarshal(bText, &updates)

			log.Println(updates.Updates[0].Message.Message)
			message := telegram.MessagesSendMessageParams{
				Message:  "answer",
				Peer:     &telegram.InputPeerUser{UserID: int32(updates.Users[0].ID)},
				RandomID: rand.Int63(),
			}
			_, msgerr := client.MessagesSendMessage(&message)
			if msgerr != nil {
				log.Panicln(msgerr.Error())
			}
			return false
		default:
			pp.Println(msg)
		}

		return false
	})

	message := telegram.MessagesSendMessageParams{
		Message:  "Started",
		Peer:     &telegram.InputPeerUser{UserID: int32(MYIDHERE)},
		RandomID: rand.Int63(),
	}
	log.Println(message.Message)

	client.UpdatesGetState()

	_, msgerr := client.MessagesSendMessage(&message)
	if msgerr != nil {
		log.Panicln(msgerr.Error())
	}
	// we need to call updates.getState, after that telegram server will send you updates
	_, err := client.UpdatesGetState()
	dry.PanicIfErr(err)
	// this state could be useful, if you want to get old unread updates
	//pp.Println(state)

	var wg sync.WaitGroup
	wg.Add(1)
	wg.Wait()
}

And a behavior:

I don't know what is the reason, but it stuck only at.
_, msgerr := client.MessagesSendMessage(&message)
If i don't answer to the user it pass great.
