[1.15.2 | SOLVED] TileEntity is missing a mapping

As I was making a TileEntity for my minecraft mod, I encountered the following problem:

The TileEntity was just working fine, but the client threw an error on the write() method:

[19:43:55] [Server thread/ERROR] [minecraft/Chunk]: A TileEntity type ch.virt.wandsforge.tileentity.TileWandPedestal has thrown an exception trying to write state. It will not persist, Report this to the mod author

After a bit of research, I found out, that there must be something wrong with registering the TileEntity, so here is my Class where I initialize my TileEntities:

@ObjectHolder(WandsMain.MODID)
@Mod.EventBusSubscriber(modid = WandsMain.MODID, bus = Mod.EventBusSubscriber.Bus.MOD)
public class TileInit {

    public static final TileEntityType<TileWandPedestal> WAND_PEDESTAL_TALL = (TileEntityType<TileWandPedestal>) TileEntityType.Builder.create(() -> new TileWandPedestal(true), BlockInit.WAND_PEDESTAL_TALL).build(null).setRegistryName("wand_pedestal_tall");

    @SubscribeEvent
    public void registerTileType(final RegistryEvent.Register<TileEntityType<?>> e){
        e.getRegistry().register(WAND_PEDESTAL_TALL);
    }

    public static void bindRenderers(){
        ClientRegistry.bindTileEntityRenderer(WAND_PEDESTAL_TALL, (Function<TileEntityRendererDispatcher, TileEntityRenderer<TileWandPedestal>>) tileEntityRendererDispatcher -> new RendererWandPedestal(tileEntityRendererDispatcher));
    }
}

Does anyone know what could be wrong?

Thanks in advance!
