How can you remove the values “Empty list”?
You can use custom node “Clear List” from Archi-lab package to clean your empty lists. Good Luck!
Use “List.Map” along with List.Empty. Then Filter your list with “FilterByboolMask”. I will post workflow tomorrow currently i am away from my PC.
You can also connect “ListIsEmpty” lacing to longest then use "FilterByBoolMask to filter out Empty list.
