Hi @ArliArdevlirn, welcome to the Glitch Forums!

Unfortunately that information doesn’t give us much to go on - those are pretty generic “OMG something’s wrong and you’re not doing anything about it!” messages. However the ECONNREFUSED message leads me to believe that perhaps you’ve got the debugger running and that’s causing you some problems.

If you open your Logs pane by clicking on the “Logs” button under your project’s name do you see a little stop sign icon: image ? If so, what happens if you click on it?

@cori Yeah sorry i was in a quick rush when i first wrote my message.

I figured out what was giving me that error and i fixed it but i still have the problem from the bot instantly disconnecting from the vocal channel which mean that my playStream is instantly ending without given reason :

const dispatcher = serverQueue.connection.playStream(ytdl(song.url))
		.on('end', reason => {
			if (reason === 'Stream is not generating quickly enough.') console.log('Song ended.');
			else console.log(reason+ " : b");
			serverQueue.songs.shift();
			play(guild, serverQueue.songs[0]);
		})

when it is disconnecting i get in the console :

undefined : b

Ok I don’t know a ton about discord bots, so hopefully someone who knows more can chip in here, but what I believe I can ascertain from what you posted is that your callback isn’t actually returning a reason.

If you can tell us your project name, or even the discord library you’re using, we might be able to find out something more useful.

I use Discord.js
package list :

"discord.js", "node-opus", "ffmpeg-binaries"
"ytdl-core", "simple_youtube_api"
"fs", "request"

So it has happened to other people before:

After further investigation it was shown to be a race condition.
Apparently this fixes it…?

So I guess something like

const dispatcher = serverQueue.connection.playStream(ytdl(song.url))
		.on('end', reason => {
           setTimeout((reason) => 
			     if (reason === 'Stream is not generating quickly enough.') console.log('Song ended.');
			     else console.log(reason+ " : b");
		     	serverQueue.songs.shift();
	     		play(guild, serverQueue.songs[0]);
          , 200)
		})

Maybe… I’m not sure

Well no what you are proposing to me, solve an other bug only happening in an async scope and only when he is called directly after another call.
My problem is that playStream(ytdl(song.url)) instantly end even on first call.

.on('end' ()=>{})

execute his code only when he catch the event ‘end’ who is emitted by playStream() when he finished to send the stream. (actually he execute it directly only because my problem occured :frowning: )

Okay i found the origin of the problem :
playStream() need ffmpeg-binaries to be able to stream the audio on the connection.
ffmpeg-binaries need to be installed(downloaded and build) with the host console using

npm install -g ffmpeg-binaries

which can’t be done because we don’t have enought permission.

So the only hope is that someone from staff of glitch.com see this and try to fix the issue for everyone or install it in my project from a console with enought permission.

my actual project name is ‘caabfd’.

The -g flag has no effect in Glitch; packages are installed in the shared pnpm volume by default.

What do you see if you run enable-pnpmn in the console? When I add ffmpeg-binaries":"*" to my package.json in a new project and then subsequently run pnpm list in the console I see thoat package installed. Perhaps triggering a reinstall by using enable-pnpm will install that package for your use and you can see if that resolves the issue.

In this case you’ll probably want the full-screen console in case there’s an error message on install; you can access that by opening the Project Name menu, selecting Advanced Options, and then selecting Open Console.

@cori
ffmpeg-binaries was already in package.js changin is version from “^4.0.0” to “*” did nothing exept making glitch interface asking me to put it to “^4.0.0” again.

Else thank you the command enable-pnpm solved the issue by forcing ffmpeg-binaries to be build.

11

Great! By referencing “*” in the version I just mean that when I tried it out in my package.json I didn’t care which version was being installed - I didn’t expect that to resolve the problem; sorry I wasn’t more clear.

Glad you’ve gotten past that hurdle! Happy Glitching!

Just a question, my bot had no problem without installing ffmpeg binaries. I thought Glitch had ffmpeg already installed?
