At first I thought that this problem was my problem, but now I’m not sure that I did anything wrong and that’s why I’m here, I hope I’m in the right place.

I've been experimenting with this and trying to solve this problem on my own, but this is the first time I need help.

I want to create a falling block when executing the "setfallingblock" command. The command worked, but the falling block does not appear and gives an error.

Screenshots

        PacketContainer packetContainer = new PacketContainer(PacketType.Play.Server.SPAWN_ENTITY);

        packetContainer.getIntegers()
                .write(0, 22);
        packetContainer.getUUIDs()
                .write(0, UUID.randomUUID());
        packetContainer.getEntityTypeModifier()
                .write(0, EntityType.FALLING_BLOCK);

        packetContainer.getDoubles()
                .write(0, location.getX())
                .write(1, location.getY())
                .write(2, location.getZ());

        protocolManager.sendServerPacket(player, packetContainer);

I will be grateful to everyone who will help me and who will not. I don’t need ready-made code from you, I just need to at least understand the cause of this error and whether I can somehow fix it. Thank you for your attention.
