无法读取未定义的属性“表情符号”？

Question

我正在尝试制作一个具有5个不同主题的门票系统，供人们用来制作门票，但我的大部分代码都写下来了，但是当机器人试图获取表情符号的集合时，我得到了错误提示：

(node:43144) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'emoji' of undefined
    at C:\Users\nalfo\OneDrive\Desktop\Discord Bot\NetSync Beta\commands\ticket\ticket-create.js:171:39
    at processTicksAndRejections (internal/process/task_queues.js:97:5)
(node:43144) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch().

(node:43144) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

我也尝试只用表情符号名称和东西替换实际的表情符号。 这是我当前正在使用的代码：

const Discord = require('discord.js');
const db = require('quick.db');
const ms = require("parse-ms");
const randomstring = require("randomstring");

module.exports.run = async (bot, message, args) => {
  if (message.deletable) message.delete();
  let permembed = new Discord.RichEmbed()
  .setColor('#e64b0e')
  .setDescription(`An error occured: I don't have permission to manage channels.`)
  .setTimestamp()
  .setFooter(`© NetSync by Towncraft Developers`);

  if(!message.guild.me.hasPermission('MANAGE_CHANNELS')) return message.channel.send(permembed).then(msg => { msg.delete(10000) });

  let user2 = message.author;

  let timeout = 300;

  let daily = await db.fetch(`ticketcooldown_${message.guild.id}_${message.author.id}`);

  if (daily !== null && timeout - (Date.now() - daily) > 0) {
    let time = ms(timeout - (Date.now() - daily));

有什么想法吗？非常感谢。

Answer 1

您有10秒的时间限制，但您没有定义时间不足就是错误

因此将选项更改为此

{ time: 10000, errors: ["time"], max: 1 }

如果您未将其定义为错误，则它将转到.then块，然后在then块中，您认为行代码有反应

const reaction = collected.first();

如果您选择这条路线，则需要添加一个catch块

另一种选择是检查是否定义了反应，如果没有返回。
