Discord.js Bot 赠品命令：embedSent.reactions.get 不是函数

Question

我正在尝试制作一个发送嵌入的 Discord.js 赠品命令，将其保存到变量 embedSent 然后使用 reactions.get() 方法收集 TimeOut 后的反应，但我不断收到错误 TypeError: embedSent.reactions.get is not a function 这是我的代码部分：

var embed = new Discord.MessageEmbed();
embed.setColor(0x3333ff);
embed.setTitle("Nouveau Giveaway !");
embed.setDescription("**" + item + "**");
embed.addField(`Durée : `, ms(ms(time), {
  long: true
}), true);
embed.setFooter("Réagissez à ce message avec ???? pour participer !");
var embedSent = await message.channel.send(embed);
embedSent.react("????");

setTimeout(function () {
  var peopleReacted = embedSent.reactions.get("????").users.filter(user => user.id !== client.user.id).array()
}, time);

好的，经过将近 2 个月，我终于弄明白了。完整的工作命令（DiscordJS v12）：

if (command == "giveaway") {
    // !giveaway {time s/m/d} {item}
    const messageArray = message.content.split(" ");
    if (!message.member.hasPermission(["ADMINISTRATOR"])) return message.channel.send("You don't have enough permissions to start a giveaway !")
    var item = "";
    var time;
    var winnerCount;
    for (var i = 1; i < args.length; i++) {
      item += (args[i] + " ");
    }
    time = args[0];
    if (!time) {
      return message.channel.send(`Invalid duration provided`);
    }
    if (!item) {
      item = "No title"
    }
    var embed = new Discord.MessageEmbed();
    embed.setColor(0x3333ff);
    embed.setTitle("New Giveaway !");
    embed.setDescription("**" + item + "**");
    embed.addField(`Duration : `, ms(ms(time), {
      long: true
    }), true);
    embed.setFooter("React to this message with ? to participate !");
    var embedSent = await message.channel.send(embed);
    embedSent.react("?");

    setTimeout(async () => {
      try{
        const peopleReactedBot = await embedSent.reactions.cache.get("?").users.fetch();
        var peopleReacted = peopleReactedBot.array().filter(u => u.id !== client.user.id);
      }catch(e){
        return message.channel.send(`An unknown error happened during the draw of the giveaway **${item}** : `+"`"+e+"`")
      }
      var winner;

      if (peopleReacted.length <= 0) {
        return message.channel.send(`Not enough participants to execute the draw of the giveaway **${item}** :(`);
      } else {
        var index = Math.floor(Math.random() * peopleReacted.length);
        winner = peopleReacted[index];
      }
      if (!winner) {
        message.channel.send(`An unknown error happened during the draw of the giveaway **${item}**`);
      } else {
        console.log(`Giveaway ${item} won by ${winner.toString()}`)
        message.channel.send(`? **${winner.toString()}** has won the giveaway **${item}** ! Congratulations ! ?`);
      }
    }, ms(time));
}

希望对大家有所帮助！

我猜这个赠品命令对我有用 - Discord.js V13

• 如果您还没有安装 npm i ms，请不要忘记安装

const { Client, Intents, CommandInteraction, ReactionUserManager } = require('discord.js'); 
const INTENTS = new Intents(32767); // 32767 == full intents, calculated from intent calculator 

const client = new Client({
  intents: INTENTS
});

const Discord = require('discord.js');
const ms = require('ms') // make sure package ms is downloaded in console, to do this, simply type:   npm i ms     in your terminal
// https://www.npmjs.com/package/ms

client.once("ready" , () => {
    console.log("I am online!")
});

client.on('messageCreate', async message => {

    const prefix = "!" // this can be any prefix you want
    let args = message.content.substring(prefix.length).split(" ")

    // COMMAND FORMAT: !startgiveaway {duration} {winners} {#channel} {prize}
    // E.g. !startgiveaway 24h 3w #giveaways Free Discord Nitro

    if ((message.content.startsWith(`${prefix}startgiveaway`))) { // this condition can be changed to any command you'd like, e.g. `${prefix}gstart`
        if (message.member.roles.cache.some(role => (role.name === 'Giveaway') )) { // user must have a role named Giveaway to start giveaway
        let duration = args[1];
        let winnerCount = args[2];

        if (!duration) 
            return message.channel.send('Please provide a duration for the giveaway!\nThe abbreviations for units of time are: `d (days), h (hours), m (minutes), s (seconds)`');
