Discord.js v12 表情符号列表命令

Question

I'm trying to make an emoji list command in discord.js v12. However, if I run the command in a server with many emojis I get an Invalid Form Body error as the embed description cannot have more than 2048 characters. Hence I tried to split the message. Here is my code:

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

module.exports = {
 name: 'emojis',
 description: "Gets a guild's emojis",

 async run(client, message, args) {
  const charactersPerMessage = 2000;
  const emojis = message.guild.emojis.cache.map((e) => {
   return `${e} **-** \`:${e.name}:\``;
  });
  const numberOfMessages = Math.ceil(emojis.length / charactersPerMessage);
  const embed = new MessageEmbed().setTitle(`Emoji List`);
  for (i = 0; i < numberOfMessages; i++) {
   message.channel.send(
    embed.setDescription(
     emojis.slice(i * charactersPerMessage, (i + 1) * charactersPerMessage)
    )
   );
  }
 },
};

Even after this, I get the same Invalid Body Form error. Here is the error I get:

(node:211) UnhandledPromiseRejectionWarning: DiscordAPIError: Invalid Form Body
embed.description: Must be 2048 or fewer in length.
    at RequestHandler.execute (/home/runner/Utki-the-bot/node_modules/discord.js/src/rest/RequestHandler.js:170:25)

(node:211) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Can you help me out? Thanks in advance!

The problem is the fact that emojis is an array, not a string. The .map function returns an array (of strings in your case). The fix should be quite simple, just add a .join at the end of the .map function to make it a string. Check the code below:

const emojis = message.guild.emojis.cache
 .map((e) => `${e} **-** \`:${e.name}:\``)
 .join(', ');
