如何在 discord.js 代码中添加自定义表情符号？

Question

每当我运行我的代码时，我都会收到此错误

(node:552) UnhandledPromiseRejectionWarning: DiscordAPIError: Unknown Emoji.

我正在尝试添加自己的表情符号，但这不起作用，我是 discord.js 的初学者 这是我第一次实际使用reactionroles，所以我不知道如何使用它们。使用正常的表情符号工作，但我想使用我的自定义表情符号

这是我的代码：

const Discord = require("discord.js");
const { MessageEmbed } = require("discord.js");
const { Color } = require("../../config.js");
module.exports = {
    name: 'reactionrole',
    aliases: [],
    permissions: [],
    description: "Sets up a reaction role message!",
    run: async (client, message, args) => {
        let FortniteEmoji = client.emojis.cache.get("879625063643635713");
        let ApexEmoji = client.emojis.cache.get("879624843920809985");
        const channel = '869871201621790741';
        const RavineaRole = message.guild.roles.cache.find(role => role.name === "Fortnite Tryouts");
        const YouAgainRole = message.guild.roles.cache.find(role => role.name === "Apex Legends Tryouts");
 
        const RavineaEmoji = `FortniteEmoji`;
        const YouAgainEmoji = `ApexEmoji`;
 
        let embed = new Discord.MessageEmbed()
            .setColor('#e42643')
            .setTitle('Tryout For The Following Games!')
            .setDescription('Enter The Tryouts!\n\n'
                + `${RavineaEmoji} for Fortnite\n`
                + `${YouAgainEmoji} for Apex Legends`);
 
        let messageEmbed = await message.channel.send(embed);
        messageEmbed.react(RavineaEmoji);
        messageEmbed.react(YouAgainEmoji);
 
        client.on('messageReactionAdd', async (reaction, user) => {
            if (reaction.message.partial) await reaction.message.fetch();
            if (reaction.partial) await reaction.fetch();
            if (user.bot) return;
            if (!reaction.message.guild) return;
 
            if (reaction.message.channel.id == channel) {
                if (reaction.emoji.name === RavineaEmoji) {
                    await reaction.message.guild.members.cache.get(user.id).roles.add(RavineaRole);
                }
                if (reaction.emoji.name === YouAgainEmoji) {
                    await reaction.message.guild.members.cache.get(user.id).roles.add(YouAgainRole);
                }
            } else {
                return;
            }
 
        });
 
        client.on('messageReactionRemove', async (reaction, user) => {
 
            if (reaction.message.partial) await reaction.message.fetch();
            if (reaction.partial) await reaction.fetch();
            if (user.bot) return;
            if (!reaction.message.guild) return;
 
 
            if (reaction.message.channel.id == channel) {
                if (reaction.emoji.name === RavineaEmoji) {
                    await reaction.message.guild.members.cache.get(user.id).roles.remove(RavineaRole);
                }
                if (reaction.emoji.name === YouAgainEmoji) {
                    await reaction.message.guild.members.cache.get(user.id).roles.remove(YouAgainRole);
                }
            } else {
                return;
            }
        });
    }
 
}

当您将表情符号定义为字符串时，它会出现，因此您尝试使用字符串对消息做出反应，但这是行不通的。

解决方案：

const Discord = require("discord.js");
const { MessageEmbed } = require("discord.js");
const { Color } = require("../../config.js");
module.exports = {
    name: 'reactionrole',
    aliases: [],
    permissions: [],
    description: "Sets up a reaction role message!",
    run: async (client, message, args) => {
        let FortniteEmoji = client.emojis.cache.get("879625063643635713");
        let ApexEmoji = client.emojis.cache.get("879624843920809985");
        const channel = '869871201621790741';
        const RavineaRole = message.guild.roles.cache.find(role => role.name === "Fortnite Tryouts");
        const YouAgainRole = message.guild.roles.cache.find(role => role.name === "Apex Legends Tryouts");
 
        const RavineaEmoji = FortniteEmoji;
        const YouAgainEmoji = ApexEmoji;
 
        let embed = new Discord.MessageEmbed()
            .setColor('#e42643')
            .setTitle('Tryout For The Following Games!')
            .setDescription('Enter The Tryouts!\n\n'
                + `${RavineaEmoji} for Fortnite\n`
                + `${YouAgainEmoji} for Apex Legends`);
 
        let messageEmbed = await message.channel.send(embed);
        messageEmbed.react(RavineaEmoji);
        messageEmbed.react(YouAgainEmoji);
 
        client.on('messageReactionAdd', async (reaction, user) => {
            if (reaction.message.partial) await reaction.message.fetch();
            if (reaction.partial) await reaction.fetch();
            if (user.bot) return;
            if (!reaction.message.guild) return;
 
            if (reaction.message.channel.id == channel) {
                if (reaction.emoji.name === RavineaEmoji)
                    await reaction.message.guild.members.cache.get(user.id).roles.add(RavineaRole);
                if (reaction.emoji.name === YouAgainEmoji)
                    await reaction.message.guild.members.cache.get(user.id).roles.add(YouAgainRole);
            } else
                return;
        });
        client.on('messageReactionRemove', async (reaction, user) => {
            if (reaction.message.partial) await reaction.message.fetch();
            if (reaction.partial) await reaction.fetch();
            if (user.bot) return;
            if (!reaction.message.guild) return;

            if (reaction.message.channel.id == channel) {
                if (reaction.emoji.name === RavineaEmoji) {
                    await reaction.message.guild.members.cache.get(user.id).roles.remove(RavineaRole);
                }
                if (reaction.emoji.name === YouAgainEmoji) {
                    await reaction.message.guild.members.cache.get(user.id).roles.remove(YouAgainRole);
                }
            } else {
                return;
            }
        });
    }
