这是我的代码，我收到此错误： RangeError [EMBED_DESCRIPTION]: MessageEmbed description must be a string 有人可以帮我吗？我从v12更新到v13，现在出现这个错误，还没有找到解决办法。

const { MessageEmbed } = require('discord.js');
const Command = require('../../Structures/Command');

module.exports = class extends Command {

    constructor(...args) {
        super(...args, {
            aliases: ['halp'],
            description: 'Displays all the commands in the bot',
            category: 'Utilities',
            usage: '[command]'
        });
    }

    async run(message, [command]) {
        const embed = new MessageEmbed()
            .setColor('BLUE')
            .setAuthor(`${message.guild.name} Help Menu`, message.guild.iconURL({ dynamic: true }))
            .setThumbnail(this.client.user.displayAvatarURL())
            .setFooter(`Requested by ${message.author.username}`, message.author.displayAvatarURL({ dynamic: true }))
            .setTimestamp();

        if (command) {
            const cmd = this.client.commands.get(command) || this.client.commands.get(this.client.aliases.get(command));

            if (!cmd) return message.channel.send(`Invalid Command named. \`${command}\``);

            embed.setAuthor(`${this.client.utils.capitalise(cmd.name)} Command Help`, this.client.user.displayAvatarURL());
            embed.setDescription([
                `**❯ Aliases:** ${cmd.aliases.length ? cmd.aliases.map(alias => `\`${alias}\``).join(' ') : 'No Aliases'}`,
                `**❯ Description:** ${cmd.description}`,
                `**❯ Category:** ${cmd.category}`,
                `**❯ Usage:** ${cmd.usage}`
            ]);

            return message.channel.send(embed);
        } else {
            embed.setDescription([
                `These are the available commands for ${message.guild.name}`,
                `The bot's prefix is: ${this.client.prefix}`,
                `Command Parameters: \`<>\` is strict & \`[]\` is optional`
            ]);
            let categories;
            if (!this.client.owners.includes(message.author.id)) {
                categories = this.client.utils.removeDuplicates(this.client.commands.filter(cmd => cmd.category !== 'Owner').map(cmd => cmd.category));
            } else {
                categories = this.client.utils.removeDuplicates(this.client.commands.map(cmd => cmd.category));
            }

            for (const category of categories) {
                embed.addField(`**${this.client.utils.capitalise(category)}**`, this.client.commands.filter(cmd =>
                    cmd.category === category).map(cmd => `\`${cmd.name}\``).join(' '));
            }
            return message.channel.send(embed);
        }
    }

};

标签： discord.js

【解决方案1】：

由于您将 discord.js 更新到 v13，<MessageEmbed>.setDescription 不再接受数组，您需要输入一个字符串或使用 <Array>.join，如下所示：

embed.setDescription([
  `These are the available commands for ${message.guild.name}`,
  `The bot's prefix is: ${this.client.prefix}`,
  `Command Parameters: \`<>\` is strict & \`[]\` is optional`
].join('\n'));

【解决方案2】：

Discord.js 需要一个字符串，但你给它一个数组。我会从 setDescriptions 中删除数组括号 [ ] 和逗号
