Why is Discord JS 12 music not playing?

Question

YouTube

const Discord = require('discord.js');
const ytdl = require('ytdl-core');
const QuickYtSearch = require('quick-yt-search'); // Require the package
const YoutubeSearcher = new QuickYtSearch({
    YtApiKey: 'Тут есть апи' // Place your YouTube API key here
});
module.exports = {
  name: 'play',
  description: 'Plays a song.',
  execute(message, args) {
        const voiceChannel = message.member.voice.channel

        args = message.content.split(' '); // Занесли в массив всё содержание сообщения

    args.splice(0, 1); // Начиная с позиции 0, удалили 2 элемента из массива

    args = args.join(' '); // Объединили все элементы в массиве

        if (!voiceChannel) return message.reply('Войдите в голосовой канал!')
        const permissions = voiceChannel.permissionsFor(message.client.user)
        if (!permissions.has('CONNECT')) return message.reply('У меня нет прав для того, чтобы присоединиться к каналу!')
        if (!permissions.has('SPEAK')) return message.reply('Я не могу проигрывать музыку!')

        YoutubeSearcher.getVideo(args).then(video => {
            voiceChannel.join().then(connection => {
                const stream = ytdl(video.url, { filter: 'audioonly' });
                const dispatcher = connection.play(stream);
    
                dispatcher.on('finish', () => voiceChannel.leave());
            });
        });
  },
};

To play music using the library you are using, FFmpeg or avconv is required. Download the FFmpeg/avconv executable and place it in the PATH/folder of the bot executable.
