[1.18.1] Creating a new Dimension

[steakmans]

Hi,

I'm trying to make a custom dimension with the new data driven system. I can't manage to make the game work with it. Every time I try to create a world, the game says that there was a problem with a datapack. I checked the logs and I think it is a registry problem.
Here is the error:

[09:54:52] [Render thread/WARN]: Failed to load datapacks, can't proceed with server load

And here is my ModDimension class:

package fr.steakmans.futurcraft.dimension;

import fr.steakmans.futurcraft.Main;
import net.minecraft.core.Registry;
import net.minecraft.resources.ResourceKey;
import net.minecraft.resources.ResourceLocation;
import net.minecraft.world.level.Level;
import net.minecraftforge.registries.ForgeRegistries;

public class ModDimensions {

    public static final ResourceKey<Level> MOON = ResourceKey.create(Registry.DIMENSION_REGISTRY, new ResourceLocation(Main.MODID, "moon"));

}

Thanks.

Probably you solve this but someone gonna search like me and no found the answer

Make sure all `/dimension/mydim.json` and `/dimension_type/mydim.json` are correct, when someting in these jsons is wrong, minecraft no register the info(? is weird, i donk know what happens.
