In a form, the slot that I want to request is a list. This slot is never requested What I’m seeing is that when the form action is called, the slot is set to an empty list before we get to actions I can control in stories or rules. My guess is it’s not being requested is because it’s not null or None. Has anybody else seen this? Is there a work around?

Hey @boristhescot , try change utterances for slots like this “utter_ask_<slot_name>”.

@EvanMath It still skips prompting for the list slot.

Just in case there is confusion, the form does prompt for the text slot. It only skips the list slot

Hey @boristhescot , have you defined the “entities” section in your domain file? Because I can’t see that above.

@EvanMath , I updated the domain to include entities. It doesn’t make a difference for purposes of reproduction, but it’s good to make sure things are correct

@Gehova , Thanks for pointing me to that solution. I came back to Rasa because I saw that they fixed the issue of single elements not being stored as an element of a list. It’s disappointing that they didn’t see the case of prompting for an empty list as they were working on it. If there’s no way to do this outside of a custom solution, I guess that’s what I’ll have to do.

Yes, the problem is that an empty list is still a list. Check this thread for a solution with two slots.
