Question

Hi everyone I wanted to ask if any of you could solve the following problem:
I wanted to fail audio in a voice channel but I can't, I managed to connect to the channel but when I have to run the audio file crashes
When I install the modules it gives me the following errors:

> node install.js

Answer 1

These are just warnings. Not errors. There is no need to be alarmed, in the future if you see these warnings just know, 99% of the time ignore them and you should be fine.

Answer 2

I found that instead of channel I had to put connection.play, but now the bot enters and does nothing does not even give an error the piece of code to run the file is as follows:
var channel = message.guild.channels.cache.get("842859974324518913")
if (!channel) return console.error("The channel does not exist!");
channel.join().then(connection => {
const dispatcher = connection.play('./audios/private.mp3');
dispatcher.on("end", end => {
channel.leave();
});
});
