/stop command not working

[Hypnos2137]

Hi, bot responds to '/stop' command with ':(' and does nothing.
I've noticed that commands like '/bassboost' and '/vaporwave' are not working as well.
/play, /pause, /skip, /resume and a lot of other commands work, so it's usable.
It seems that command /volume registers the change with a reply that it's changed, but it doesn't really do that, so volume control via slash commands is not working.

I'm also attaching a ss with errors when launching the bot. I don't know if it's related.

I'm wondering what is causing the issue.

The reason it doesn't work is that the stop command has not yet been implemented after the change to slash commands. And the error regarding the "ready" event are displayed because the official erela.js repository is not maintained and is missing some of the new lavalink features.
