"Map List Items" option is not available

Actions & Logic

Hi,

I am trying to populate a choice chip using a datetime field from a firestore collection. While trying to set a variable of type List <DateTime> or List <Anything>, I want to select the collection slots, and I except an option called Map List Items -> and then select the field slot_start_time to be converted to a list. This is based on tutorials/documentation I've looked at so far. Examples:

(from issue - https://community.flutterflow.io/ask-the-community/post/map-list-items-current-variable-is-not-valid-aFG5DzNzVGsr5hk)

(from video - https://www.youtube.com/watch?v=8QU3P0w4GK8&list=PLegYPCD7QFt0066WjGoUT5jS4GT4mE3q2&index=3)

However, I see the following:

I have tried a lot of different ways, using custom code to convert a column to a list, and creating a page state variable and updating it by adding an item - but I am not able to resolve it.

Essentially I want to create a choice chip with the available slots, which are captured in the slots collection. I want to display the slot_start_time field as the options.

What have you tried so far?
