I am trying to create an entity, but It doesn't work on client side. I have tried creating a custom packet that spawns the entity on the client, but that entity disappears after about 3 ticks for no reason. When I try to use 

NetworkHooks.getEntitySpawningPacket(this);

In createSpawnPacket, I get this error:

I have no Idea why in the world I'm getting this error as I have

.setCustomClientFactory((InventoryFallingBlockEntity::new))

When registering my entity...

 

Registry code:

@Mod.EventBusSubscriber(bus = Mod.EventBusSubscriber.Bus.MOD)
public class EntityRegistry {

    public static EntityType<InventoryFallingBlockEntity> AMPHORE;

    @SubscribeEvent
    public static void registerEntities(RegistryEvent.Register<EntityType<?>> event) {
        IForgeRegistry<EntityType<?>> registry = event.getRegistry();

        AMPHORE = EntityType.Builder.<InventoryFallingBlockEntity>create(InventoryFallingBlockEntity::new, EntityClassification.MISC)
                .size(0.98F, 0.98F)
                .setCustomClientFactory((InventoryFallingBlockEntity::new))
                .build("amphore");
        AMPHORE.setRegistryName("amphore");

        registry.registerAll();
    }

}

This is embarassing...

registry.registerAll();
