Can someone tell me what's wrong with my code (Solved).

[AGMPenguin]

I was working on a mod for Minecraft 1.19.2, but after the latest changes, whenever I would launch Minecraft, I would get this error:

More Ores for MC (mofmc) has failed to load correctly

java.lang.reflect.InvocationTargetException: null

Is anyone able to tell me what's wrong? Thanks.

 

The Source code is at the following link: https://github.com/MOFMC/More-Ores-for-MC/tree/1.19.2

This is the crash report:

You're calling the supplier before the objects are registered, resulting in an NPE. Whenever creating constructor methods for registering, it's safest to assume all parameters, except the name, should be supplied instances rather than the raw object.
