'use strict';
const { Wechaty } = require('wechaty');

const bot = Wechaty.instance();
bot.on('scan', url => {
  const loginurl = url.replace('qrcode', 'l');
  require('qrcode-terminal').generate(loginurl);
  console.log(url);
})
  .on('login', user => {
    console.log(`${user} login`);
  })
  .on('friend', async function name(contact, request) {
    if (request) {
      await request.accept();
      console.log(`Contact: ${contact.name()} send Request ${request.hello}`);
    }
  })
  .on('message', async function(m) {
    const contact = m.from();
    const content = m.content();
    const room = m.room();
    if (room) {
      console.log(`Room:${room.topic()}  Contact:${contact.name()}  Content: ${content}`);
    } else {
      console.log(`Contact: ${contact.name()} Content:${content}`);
    }
    if (m.self()) {
      return;
    }
    if (/hello/.test(content)) {
      m.say('hello how are you');
    }
    if (/room/.test(content)) {
      const keyroom = await bot.Room.find({ topic: 'test' });
      if (keyroom) {
        try {
          // console.log(contact);
          // await keyroom.add(contact);
          const roResult = await keyroom.add(contact);
          console.log(`roResult is ${roResult}`);
        } catch (error) {
          console.error(error);
        }
        await keyroom.say('welcome', contact);
      }
    }
    if (/out/.test(content)) {
      const keyroom = await bot.Room.find({ topic: 'test' });
      if (keyroom) {
        await keyroom.say('Remove from room', contact);
        await keyroom.del(contact);
      }
    }
  })
  .init();
const roResult = await keyroom.add(contact);

the roResult is undefined;it doesn't join the keyroom.
