Custom block error with text conversion

I think this is one of those situation where a few pictures may help better than me explaining:
list and variable utilities script pic
list and variable utilities script pic (1)
list and variable utilities script pic (2)
list and variable utilities script pic (3)
list and variable utilities script pic (4)
for some reason, linking the list fixes the issue, but that shouldn’t be the solution in the first place.

An empty list element is internally an empty string.
“Replace item” with the empty slot makes an item a null.
Calling a HOF makes it ‘’ again.

Still, this should be fixed…

I’m glad you were able to figure out the issue, but now it seems like a bug to me :slight_smile:
I think an empty string when put into the text of block should behave as null.

Yes, I think so.
