Why does this code not display the pop-up window?

• Server returns

{"ok":false,"error_code":400,"description":"Bad Request: query is too old and response timeout expired or query ID is invalid"}

• my code

func Alert(bot *tele.Bot) {
	bot.Handle("/start", func(c tele.Context) error {
		c.Reply("welcome", RepButtons(bot))
		return nil
	})
}

// RepButtons
func RepButtons(bot *tele.Bot) *tele.ReplyMarkup {
	menuMain := &tele.ReplyMarkup{ResizeKeyboard: true}
	var btns []tele.Btn
	var btnDelete = &tele.InlineButton{Unique: "unique123", Text: "Delete"}
	query := menuMain.Data("queryBtn", "unique123", "welcome")
	bot.Handle(btnDelete, func(c tele.Context) error {
		return c.Respond(&tele.CallbackResponse{Text: "HAHA", ShowAlert: true})
	})
	btns = append(btns, query)
	menuMain.Inline(btns)
	return menuMain
}

Why does nothing happen when I click the button?

correct code

func Alert(bot *tele.Bot) {
	bot.Handle("/start", func(c tele.Context) error {
		c.Reply("welcome", RepButtons(bot))
		return nil
	})
}

// RepButtons
func RepButtons(bot *tele.Bot) *tele.ReplyMarkup {
	menuMain := &tele.ReplyMarkup{ResizeKeyboard: true}
	var btns []tele.Btn
	query := menuMain.Data("queryBtn", "unique123", "welcome")
	bot.Handle(&query, func(c tele.Context) error {
		return c.Respond(&tele.CallbackResponse{Text: "HAHA", ShowAlert: true})
	})
	btns = append(btns, query)
	menuMain.Inline(btns)
	return menuMain
}
