TypeError: voiceChannel.join is not a function

I'm new to coding in general so expect nooby behaviour.

My Discord Bot goes online with the command node . and I try my !ping command and everything works just fine. But when I try the declared command !play to play a video from YT but when I press enter the bot crashes with the log:

const connection = await voiceChannel.join(); ^
TypeError: voiceChannel.join is not a function at Object.execute (D:\Discord Bot\commands\play.js:43:48) at Client.<anonymous> (D:\Discord Bot\main.js:33:41) at Client.emit (node:events:394:28) at MessageCreateAction.handle (D:\Discord Bot\node_modules\discord.js\src\client\actions\MessageCreate.js:31:18) at Object.module.exports [as MESSAGE_CREATE] (D:\Discord Bot\node_modules\discord.js\src\client\websocket\handlers\MESSAGE_CREATE.js:4:32) at WebSocketManager.handlePacket (D:\Discord Bot\node_modules\discord.js\src\client\websocket\WebSocketManager.js:345:31) at WebSocketShard.onPacket (D:\Discord Bot\node_modules\discord.js\src\client\websocket\WebSocketShard.js:443:22) at WebSocketShard.onMessage (D:\Discord Bot\node_modules\discord.js\src\client\websocket\WebSocketShard.js:300:10) at WebSocket.onMessage (D:\Discord Bot\node_modules\ws\lib\event-target.js:132:16) at WebSocket.emit (node:events:394:28)

This is the main code:

const client = new Discord.Client({ intents: ["GUILDS", "GUILD_MESSAGES"] });
const prefix = '!';
const fs = require('fs');
const { join } = require('path');
client.commands = new Discord.Collection();
const commandFiles = fs.readdirSync('./commands/').filter(file => file.endsWith('.js'));
for(const file of commandFiles){ const command = require(`./commands/${file}`); client.commands.set(command.name, command);
}
client.once('ready', () => { console.log('Mein Mussig Bot ist nun online!');
});
client.on('message', message =>{ if(!message.content.startsWith(prefix) || message.author.bot) return; const args = message.content.slice(prefix.length).split(/ +/); const command = args.shift().toLowerCase(); if(command === 'ping'){ client.commands.get('ping').execute(message,args); } else if (command === 'play'){ client.commands.get('play').execute(message,args); } else if (command === 'stop'){ client.commands.get('stop').execute(message,args); }
});
client.login('token')

This is the play command code:

const ytdl = require('ytdl-core');
const ytSearch = require('yt-search');
module.exports = { name: 'play', description: 'Joins and plays a video from youtube', async execute(message, args) { const voiceChannel = message.member.voice.channel; if (!voiceChannel) return message.channel.send('You need to be in a channel to execute this command!'); const permissions = voiceChannel.permissionsFor(message.client.user); if (!permissions.has('CONNECT')) return message.channel.send('You dont have the correct permissins'); if (!permissions.has('SPEAK')) return message.channel.send('You dont have the correct permissins'); if (!args.length) return message.channel.send('You need to send the second argument!'); const validURL = (str) =>{ var regex = /(http|https):\/\/(\w+:{0,1}\w*)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%!\-\/]))?/; if(!regex.test(str)){ return false; } else { return true; } } if(validURL(args[0])){ const connection = await voiceChannel.join() .catch(console.error); const stream = ytdl(args[0], {filter: 'audioonly'}); connection.play(stream, {seek: 0, volume: 1}) .on('finish', () =>{ voiceChannel.leave(); message.channel.send('leaving channel'); }); await message.reply(`:thumbsup: Now Playing ***Your Link!***`) return } const connection = await voiceChannel.join(); const videoFinder = async (query) => { const videoResult = await ytSearch(query); return (videoResult.videos.length > 1) ? videoResult.videos[0] : null; } const video = await videoFinder(args.join(' ')); if(video){ const stream = ytdl(video.url, {filter: 'audioonly'}); connection.play(stream, {seek: 0, volume: 1}) .on('finish', () =>{ voiceChannel.leave(); }); await message.reply(`:thumbsup: Now Playing ***${video.title}***`) } else { message.channel.send('No video results found'); } }
}

I know I am like a month late but whoever sees this, after the new update of Discord JS v13, joining a voice channel is now like this:

import { joinVoiceChannel } from "@discordjs/voice";
const connection = joinVoiceChannel(
{ channelId: message.member.voice.channel, guildId: message.guild.id, adapterCreator: message.guild.voiceAdapterCreator
});

More info on @discordjs/voice here. Run npm i @discordjs/voice to install.

Because of the updates and changes from Discord v12 to Discord v13 (see here, you would have to install another package called @discord/voice. You can install it (including the required encryption package) via three different ways:

• Npm: npm install @discordjs/voice libsodium-wrappers
• Yarn: yarn add @discordjs/voice libsodium-wrappers
• Pnpm: pnpm add @discordjs/voice libsodium-wrappers

Please refer to the guide for more information about upgrading from Discord v12 to Discord v13.
