Hello, recently I have tried uploading an addon to the workshop, this addon being a pack of .mp3 files for custom sounds in my server.

Unfortunately this error pops up



Creating temporary addon.json.

Looking in folder "C:/Users/myname/Desktop/066sounds/"

	roll.mp3
		[Not allowed by whitelist]
File list verification failed
Creation OK!

Is there any possible way to fix this? Also here is a picture of my file.

The sounds have to be in the sound/ directory.

The folder needs to be named sound not sounds

okay, so now i got that figured out but supriseā€¦
more errors

Hi Clunky,

You need to make an icon for it, for when its on the workshop.
