[1.15.2] Biome registry

[lIwoodyIl]

Hello! I am new to modding and came upon an error in my registry handler while trying to register my custom biome. 

public static final RegistryObject<Biome> OBSIDIAN_BIOME = BIOMES.register("obsidian_biome", ObsidianBiome::new);

The error here is: "Inferred type 'I' for type parameter 'I' is not within its bound; should extend 'net.minecraft.world.biome.Biome". I have a deferred register and a FMLJavaLoadingContext for BIOMES. If any more of my code or any info is required I can send it. Sadly im not too sure how all this registry stuff works so help would be greatly appreciated, thanks.

This is a java error stating that your inferred type is not an instance of the biome class. I would assume we would find a similar issue within the class itself.
