Discord JS 反应错误

Question

谁能向我解释为什么我在尝试从反应中获取我的角色时收到此错误： UnhandledPromiseRejectionWarning: TypeError: reaction.users.last is not a function？谢谢，我也附上了代码。

代码：

const Discord = require('discord.js');
const client = new Discord.Client();
const config = require('./config.json');

client.on('ready', () => {
 console.log('Ready!');
});

client.on('message', async (message) => {
 if (message.content === 'l!verify') {
  const reactmessage = await message.channel.send(
   'Am intrebat 100 de Romani, vrei rolul de GUEST?'
  );
  await reactmessage.react('????');

  const filter = (reaction, user) => reaction.emoji.name === '????' && !user.bot;
  const collector = reactmessage.createReactionCollector(filter, {
   time: 15000,
  });
  collector.on('collect', async (reaction) => {
   const user = reaction.users.last();
   const guild = reaction.message.guild;
   const member = guild.member(user) || (await guild.fetchMember(user));
   member.addRole(config.roleid);
  });
 }
});
client.login(config.token);

MessageReaction.users 返回 ReactionUserManager，而不是 Collection。确保使用cache 属性。

const user = reaction.users.cache.last();
