Fabric instance crashing when creating custom item group

Question

I tried making a custom item group for my mod but when I run the code, the game instantly crashes.

fabric 1.19.2

package com.end3r.cripplingteas.item;

import com.end3r.cripplingteas.CripplingTeasMod;
import com.end3r.cripplingteas.Registry.ModItems;
import net.fabricmc.fabric.api.client.itemgroup.FabricItemGroupBuilder;
import net.minecraft.item.ItemGroup;
import net.minecraft.item.ItemStack;
import net.minecraft.util.Identifier;

public class ModItemGroup {
    public static final ItemGroup CRIPPLINGTEAS = FabricItemGroupBuilder.build(
            new Identifier(CripplingTeasMod.teas, "Crippling Teas"), () -> new ItemStack(ModItems.BASIC_TEA))
            ;

}

i tried writing a custom item group for my mod using FabricItemGroupBuilder

logs:

Answer 1

You should follow the identifier rules. Crippling Teas isn't valid as:

• contains a space
• with upper cases

Actually, identifier should only be like crippling_teas .
