Discord.js语音:无法播放ytdl流

Question

我正在尝试通过Discord.js/voice和ytdl播放YT音频。我有这个代码(在play命令中)

...
const voiceChannel = message.member.voice.channel;
        // console.log(args, voiceChannel)
        if (!voiceChannel)
          return message.channel.send(
            "You need to be in a voice channel to play music!"
          ); 
        const permissions = voiceChannel.permissionsFor(message.client.user);
        if (!permissions.has("CONNECT") || !permissions.has("SPEAK")) {
          return message.channel.send(
            "I need the permissions to join and speak in your voice channel!"
          );
        }

        const songInfo = await ytdl.getInfo(args[0]);
        const song = {
            title: songInfo.videoDetails.title,
            url: songInfo.videoDetails.video_url,
        };
        console.log(song)

        let conn = await voice.joinVoiceChannel({
            channelId: voiceChannel.id,
            guildId: message.guild.id,
            adapterCreator: message.guild.voiceAdapterCreator,
            selfDeaf: false,
            selfMute: false
        })
        let conn2= voice.getVoiceConnection(voiceChannel.id)
        console.log(conn2)
        const stream = ytdl(song.url)
        conn2.subscribe(stream)
...

机器人拥有所有的烫发，在我所在的通道中正确加入，但在conn2.subscribe(stream)行给出了错误：

TypeError: Cannot read properties of undefined (reading 'subscribe')
    at Object.execute (%mypath%\musicbot2\commands\play.js:39:15)
    at runMicrotasks (<anonymous>)
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

我找不到关于这个错误的任何东西。如何正确播放音乐/音频？在这种情况下，使用ytdl，也可以使用其他站点和包。

谢谢

getVoiceConnection函数接受一个行会id，而不是一个渠道id。

将其更改为以下内容应该是可行的：

let conn2 = voice.getVoiceConnection(message.guild.id)
