Question

我只会发布导致我出错的代码部分。

当我运行机器人时，它大约需要3秒钟的时间，并且机器人因我下面的错误而崩溃。

如果它有助于解决错误，该机器人是支持用户的票证机器人，它包含对表情符号的反应，并且该机器人创建了一个具有权限和消息的房间，您可以关闭票证和该房间已被删除。

const discord = require('discord.js');
const client = new discord.Client();

const config = require('./config.json');
var userTickets = new Map();

client.login(config.token);

client.on('ready', () => {
    console.log(client.user.username + " has logged in.");

    client.user.setPresence( {
        status: "online",
        game: {
            name: "Tickets",
            type: "WATCHING"
        }
    })
});

// code

client.on('message', message => {
    if(message.author.bot) {
        if(message.embeds.length === 1 && message.embeds[0].description.startsWith('Reacc')) {
            message.react(idemoji1).then( () => message.react(idemoji2)).then( () =>  message.react(idemoji3))
            .then(msgReaction => console.log('reacted'))
            .catch(err => console.log(err));
        }
        if(message.embeds.length === 1 && message.embeds[0].description == '¡Gracias por crear el ticket!\nEl soporte se pondrá en contacto contigo lo antes posible.\n\nPor favor, responde las preguntas que se te hacen a continuación para poder date el mejor soporte.\n\n Si no escribes nada, el ticket se cerrará en 2 horas.\n\nPara cerrar este ticket reacciona a ?') {
            message.react(emoji5)
            .then(reaction => console.log("A reaccionado con " + reaction.emoji.name))
            .catch(err => console.log(err));
        }
    };

控制台错误：
