Caused by: java.lang.NullPointerException: Cannot invoke "net.minecraft.block.Block.getRequiredFeatures()" because the return value of "net.minecraft.item.BlockItem.getBlock()" is null

I've never run into this issue before. I've declared a crop block according to Kaupenjoe's tutorial and Fabric docs.

I've just implemented World Gen and Tree Generators and now this issue has risen and I'm not sure why.

    public static final Item CHORUS_ROOT = registerItem(
            "chorus_root",
            (settings) -> new BlockItem(
                    ModBlocks.CHORUS_ROOT_CROP,
                    settings.food(ModFoodComponents.CHORUS_ROOT_FOOD_COMPONENT,
                            ModFoodComponents.CHORUS_ROOT_CONSUMABLE_COMPONENT)
            ),
            new Item.Settings().food(ModFoodComponents.CHORUS_ROOT_FOOD_COMPONENT,
                    ModFoodComponents.CHORUS_ROOT_CONSUMABLE_COMPONENT)
    );

This is the item in question

post the full code of your mod initializer, ModBlocks and ModItem (i guess)

So...

#

I just kept rebuilding a bunch of times

#

And then it fixed itself

#

I think what caused it is that I tried running Datagen that would also give the crop item and item model, while the crop block already does that for it

#

And I think that muddled up my json files

#

So rerunning my datagen a few times and peering into the jsom folders seemed to fix it
