Why doesn't the bot play audio after connecting and throws an error?

Question

Node.js

When you start the bot, everything is fine, but as soon as you order a song, it gives an error

The "file" argument must be of type string. Received an instance of Object

and completes its work. FFMPEG reinstalled, downloaded the standard, binaries - nothing helped. I'm sure in the code, and I tried converting the type of the variable to ctring - the same result. I looked at the branches on the stack, github, etc. - I did not find anything sensible. I also tried the obviously working code from the tutorials on creating music bots.

At first glance, it's hard to tell what exactly the problem is.
you copied the code from here , right?
As far as I understand, this code is for an old version of discord.js, and I don't advise you to use it.
it has a lot of confusing moments, in general it is written quite badly.
try to do a simple connection and play a tune, and if everything goes smoothly - the problem was in that code (otherwise, it's FFMPEG'e).

bot.on("message", async message => {
const dispatcher = connection.play('audio.mp3');

dispatcher.on('start', () => {
  message.channel.send('audio.mp3 проигрывается!');
});

dispatcher.on('finish', () => {
  message.channel.send('audio.mp3 остановлено!');
});

dispatcher.on('error', console.error);
})
