No sound after playing a song

[Bloedarend]

When I'm in a voice channel and type /play (song), the bot joins my channel but doesn't output any sound. When typing /q it shows that the song is in the queue, and when you type /np, you get an error.

After typing /p (song):

Did you run npm install in the project folder?

[Bloedarend]

I did again to make sure, but it's still not outputting sound. I've found a similar discussion and they said it had something to do with the YouTube API. Any idea what that could be?

[Bloedarend]

npm i ytdl-core and npm i opusscript fixed it.
