I made a fabric server with Tutorials, and I only have this mod in the mods folder.
It crashed when I join the server. What could be the problem?
Server version is 1.19.3.
Thanks in advance.

I am a bit confused why this happened and currently don't have the time to look into this, but adding the jar from https://github.com/lucko/fabric-permissions-api/releases/tag/v0.2 should hopefully fix this.
