How do I add a custom attribute in 1.20?

public class Haki {
    public static final DeferredRegister<Attribute> REGISTRY = DeferredRegister.create(ForgeRegistries.Keys.ATTRIBUTES,
            Hakimod.MODID);
    public static final RegistryObject<Attribute> ARMAMENT = REGISTRY.register("armament_haki",
            ()-> new RangedAttribute("attribute.hakimod.armament", 0, 0, 200));
    public static final RegistryObject<Attribute> OBSERVATION = REGISTRY.register("observation_haki",
            () -> new RangedAttribute("attribute.hakimod.observation", 0, 0, 200));
    public static final RegistryObject<Attribute> CONQUEROR = REGISTRY.register("conqueror_haki",
            ()-> new RangedAttribute("attribute.hakimod.conqueror", 0, 0, 200));

    @SubscribeEvent
    public static void regAttr(EntityAttributeCreationEvent e){
        e.put(EntityType.PLAYER,
                AttributeSupplier.builder().add(ARMAMENT.get(), 0).build());
        e.put(EntityType.PLAYER,
                AttributeSupplier.builder().add(OBSERVATION.get(), 0).build());
        e.put(EntityType.PLAYER,
                AttributeSupplier.builder().add(CONQUEROR.get(), 0).build());
    }
}

This is my class with the Attributes.

And this is how I add them into the bus.

        modEventBus.addListener(Haki::regAttr);
        modEventBus.register(Haki.REGISTRY);

I get this error:

net.minecraftforge.fml.ModLoadingException: hakimod (hakimod) encountered an error during the common_setup event phase §7java.lang.NullPointerException: Registry Object not present: hakimod:armament_haki
