2023.3 - retrieve item from chiseled bookshelf

Hi,

I've used the functions as for any other block,

yet the account returns 0 items in slot 0 whereas "slot_0_occupied"=true.

Do you have any ideas? Is it a bug or does it work for you?

So, is there a simpler method than calculating the distance of the raytrace from the block position to retrieve the targeted slot?

Thanks in advance.

(sorry for the extra post, I didn't see the "Edit" button...)
