遇到 TypeError：无法读取 Discord.JS 中未定义的属性“0”

Question

I am trying to do a "jumbo command", but when I use the command I encounter the following error:

TypeError: Cannot read property '0' of undefined

Here's my code:

const Discord = require("discord.js");
const client = new Discord.Client();
const { Client, MessageEmbed } = require("discord.js");

module.exports = {
    name: "jumbo",
    description: "",
    execute(client, message, args) {
        if (!args[0]) return message.channel.send("Debes escribir un emoji.");

        let emoji = message.guild.emojis.cache.find((x) => x.name === args[0].split(":")[1]);

        if (!emoji) return message.channel.send("Ese no es un emoji válido.");

        const embed = new Discord.MessageEmbed().setTitle("Emoji:").setImage(emoji.url).setColor("RANDOM");

        message.channel.send(embed);
    },
};

According to the Command handling page of the Discord.js Guide , a well-formed exported module's execute method only has 2 arguments: message , and args . client does not appear to be supported as you seem to think it is. This is in line with args being undefined: no parameter at this position will be set and will thus be undefined , and would cause errors similar to/the same as the one you're currently encountering.

The aforementioned page specifically mentions how you can grab the instance of client for use in your code:

TIP

If you need to access your client instance from inside one of your command files, you can access it via message.client . [...]
