Crash on registering a SIMPLE item

[CrypticVerse]

Description

I registered an item like this:

    public static final Item MY_ITEM = register("my_item",
            new Item(new Item.Settings()));

    private static Item register(String name, Item item) {
        return Registry.register(Registries.ITEM, Identifier.of("modid", name), item);
    }

    public static void registerItems() {

    }

and put this in the Main class:

@Override
public void onInitialize() {
    MyItems.registerItems();
}

. It will crash with the following:

Try replacing "modid" with your actual mod id

[CrypticVerse]

My fabric.mod.json "modid" field matches the mod id I registered the items with.

I should also note it only crashes without FAPI. With the API, it works fine.

[JJplayz565]

Always use Fabric API, many methods and classes in the API are used in common modding.
Unless you know what you have used, just keep fabric API.
