The Problem of The Wiki of Creating an ItemGroup in The Latest Version(1.20.2)

[as-chier]

In https://fabricmc.net/wiki/tutorial:itemgroup , you can see these code
ItemGroupEvents.modifyEntriesEvent(ITEM_GROUP).register(content -> { content.add(CUSTOM_ITEM); });

It's in order to add an item into the itemgroup.
But in fact, when I copy those code into Idea , I got This Wrong
`Required type:

RegistryKey

<net. minecraft. item. ItemGroup>

Types provided:

ItemGroup`

It seems that , the parameter CUSTOM_ITEM that programmer has defined is not of the same type as Minecraft's ItemGroup like "ItemGroups.TOOLS" or "ItemGroups.BLOCKS".
CUSTOM_ITEM is a type of "ItemGroup" and the other is a type of "RegistryKey".
I has tried to understand how the wiki is different form my code,but I found that it seems just a bug of Fabric(1.20.2) or a wrong of the wiki.

Haha, I'm just a noob in fabric, so if there is any negligence on my part, please don't be too harsh on me, let's progress together with Fabric!

You can use the ItemGroup.Builder#entries method instead:

private static final ItemGroup ITEM_GROUP = FabricItemGroup.builder()
	.icon(() -> new ItemStack(CUSTOM_ITEM))
	.displayName(Text.translatable("itemGroup.tutorial.test_group"))
	.entries((context, entries) -> {
		entries.add(CUSTOM_ITEM);
	})
	.build();

I have updated the wiki page accordingly.
