I've been trying to create this mod, but every time I run my client, this error pops up.

[Vulcandium]

Caused by: net.minecraft.ResourceLocationException: Non [a-z0-9_.-] character in namespace of location: AquaticExpansion:sounds.json

-I'm aware that AquaticExpansion is capitalized, but in my mod id it isn't.

-I never made a sounds.json folder btw.

Given the error message, most likely that captialized name is a (sub)folder you created?
