Help with game crash on custom block placement

[majicmaj]

Hey all. I'm following this tutorial below to create a mod for my final project in school. When I'm placing my block (artisan station) the game is crashing for me. No one else seems to be having this problem. Can someone give it a look and help? here is my code on github, i think its this particular file that might have the issue but feel free to look around the repo.

Here is the code I have for it:

    @Override
    public BlockState getStateForPlacement(BlockItemUseContext context) {
        BlockState blockstate = super.getStateForPlacement(context);
        if (blockstate != null) {
            blockstate = blockstate.with(BlockStateProperties.FACING, context.getNearestLookingDirection());
        }
        return blockstate;
    }
	
	@Override
	protected void fillStateContainer(StateContainer.Builder<Block, BlockState> builder) {
		builder.add(BlockStateProperties.FACING);
	}
}

Create LazyOptionals once.

Is unlikely related to your issue, but it is still worth pointing out.

See this as to why:

Thank you, I traced it back to a misspelled registry. How would I implement LazyOptional once? would you mind showing me in a pull request?

Edit: also would anyone know how to implement smelting recipes? I've tried adding it but it doesnt have a method "addSmelting".
