初めに

node.jsを使ってLinebotにじゃんけん機能をつけたい。MessagingAPIを使って、Linebotは作ることができたのですがクイックリプライ機能ができません。どこがいけないのでしょうか？

コード

js
1'use strict';

3const express = require('express');
4const line = require('@line/bot-sdk');
5const PORT = process.env.PORT || 8000;
6const configs = require('./configs');
7
8const config = {
9  channelSecret: configs.lineapi.channelSecret,
10  channelAccessToken: configs.lineapi.channelAccessToken
11};
12const app = express();
13const client = new line.Client(config);
14
15app.get('/', (req, res) => res.send('Hello LINE BOT!(GET)')); //ブラウザ確認用(無くても問題ない)
16app.post('/webhook', line.middleware(config), (req, res) => {
17  console.log(req.body.events);
18
19
20  Promise
21    .all(req.body.events.map(handleEvent))
22    .then((result) => res.json(result));
23});
24
25
26function handleEvent(event) {
27  console.log(event)
28  if (event.type === 'message' && event.message.type === 'text') {
29    handleMessageEvent(event)
30  } else {
31    return Promise.resolve(null)
32  }
33}
34
35function handleMessageEvent(event) {
36  let msg = {
37    type: event.message.type,
38    text: event.message.text
