我遇到"file" argument must be a non-empty string
函数的问题。
流无法播放，并且出现以下错误：
args[0]是的，我确定'youtube.com/watch?v=A02s8omM_hI'被定义为stream，并且PassThrough的日志被记录为var stream = ytdl(args[0], { filter: "audioonly" });
message.member.voiceChannel.join().then(connection => {
const dispatcher = connection.playStream(stream);
dispatcher.on("error", (error) => {
console.log(error);
});
dispatcher.on("end", () => {
console.log("Song ended!");
});
});
（console）。

很遗憾，我在互联网上找不到与我的问题有关的任何解决方案。
预先感谢！
