tengo problemas para que mi bot se una al canal de voz y reproduzca música

el error que obtengo esCannot read properties of undefined (reading 'join')

código:

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.voicechannel;
 
 
 
 
 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();
 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 ***${video.title}!***`)
 
 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');
 }
 }
}

Solución del problema

.join()ya no funciona en discord.js v13. Necesita definir la conexión de esta manera:

const { joinVoiceChannel } = require('@discordjs/voice');
const connection = joinVoiceChannel({
 channelId: channel.id,
 guildId: channel.guild.id,
 adapterCreator: channel.guild.voiceAdapterCreator,
});
