对来自机器人的消息的反应=来自机器人的新消息

Question

那么我遗漏了什么或忘记了什么？我希望当用户对旧消息做出反应时，机器人会发送一条新消息。机器人已经对他的消息做出了反应，因此用户只需单击 A 或 B 即可做出反应。

const Discord = require('discord.js');
const { prefix, token } = require('./config.json');
const client = new Discord.Client();

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

    client.on("guildMemberAdd", async member => {
        const dmErr = false;
        try {
        await member.send(`Hello ${member}, welcome to the PotatoHost Server! 
I want to help you and so my question is: Do you want to buy a server or do you need more informations first? \n
A: I want to buy a server
B: I need more informations first \n
Please react to this message with A or B.`)
        .then(function (message) {
            message.react("")
            message.react("")

            const filter = (reaction, user) => {
                return ['', ''].includes(reaction.emoji.name) && user.id === message.author.id;
            };
        })
        message.awaitReactions(filter, { max: 1, time: 60000, errors: ['time'] })
        .then(collected => {
            const reaction = collected.first();

            if (reaction.emoji.name === '') {
                message.reply('Ok, so you want to buy a server. Let me recommend you to visit <#699374469977735208>.');
            }
            else {
                message.reply(`Ok, so you need more informations first. Let me recommend you to visit <#699374469977735208>.`);
            }
        })

        .catch(function (message) {
             console.error('One of the emojis failed to react, or the user has dms disabled.')
        })
        } catch (error) {
        dmErr = true;
        } if (dmErr === true) {
            console.log(error)
        }
        });

client.login(token);

这是错误：

(node:19044) UnhandledPromiseRejectionWarning: TypeError: Assignment to constant variable.

如错误所述，您正在尝试使用行 dmErr = true 对常量变量进行赋值。 dmErr 声明为 const。如果您打算覆盖变量的值，则应将其更改为 let。
