Seems like this is how you’re trying to create the linear items
Fist issue: seems to be with the scraper, it only got me 1 result per post.
I suggest you to re-do the scraper.
@danmelk might be able to support us here with selectors for this case.
Second issue: on Bardeen’s end. I also didn’t get any trello lists pop up
I’ve reported this here: Can't find Trello board
Hope to get updates soon!
