It took me a while to solve this and alvaro is right, but his explanation didn’t help me, but it made sense after I found it.
So for the slowpokes like me:
- In your schema in section ‘Type’ choose ‘Formula’ and
- then you get an empty input field in the ‘Options’ section
- put your code from_dataset(…) in that input field (and not in the pop-up like with other types)
Hope this helps!
