After pulling this data from Firebase, I want to create a list and add each value field to the list one by one. However, when I try to access the 2nd element with the select list item block in Kodular, I get the following error: “Select list item: Attempt to get item number 2 of a list of length 1: (Açık)”
What do I need to do to create the list correctly and access each element?
