Describe the bug
When I try to execute the /npc create command I get that an unexpected error occurred, when I place the mouse over it it says
Cannot invoke "com.mojang.authlib.GameProfile.getId()" because "$$0" is null

Platform(s)

• Fabric

Environment(s)

• Singleplayer

Versions

• Minecraft 1.20.1
• Taterzens 1.11.7

Forge or fabric? You've checked fabric but written forge.

Hey, bumping this,
Same Issue here with Fabric.
Both version 11.6 / 11.7 on 1.20.1 return the
Cannot invoke "com.mojang.authlib.GameProfile.getId()" because "$$0" is null

This was found out to be a conflict with another mod. You'll have to either remove the conflicting mod or not use taterzens :(.
