Bot musik Discord.js dengan antrian tidak berfungsi

Saya mencoba membuat Bot Discord musik dengan antrian. Saat ini, perintah putar berfungsi dan saya dapat menambahkan musik ke antrian (ditampilkan dengan perintah daftar putar saya). Masalahnya adalah ketika musik pertama berakhir, bot berhenti sepenuhnya dan tidak memutar lagu berikutnya (tidak terputus dan sepertinya sedang memutar sesuatu).
Saya menggunakan Discord.js v12, ffmpeg-static dan Youtube API .

        .catch(console.error);
    }

    const permissions = voiceChannel.permissionsFor(message.client.user);
    if (!permissions.has("CONNECT")) {
      return message.channel.send("J'ai besoin de la permission **`CONNECT`** pour cette commande");
