I am trying to create a zap that adds a line item Id to a list but before I add it to the list, I am attempting to get the list of IDs and us the values in it to compare against the current ID in a filter to have the list only be unique line item ids.
I have tried the get value and get multiple value action events but that only returns something like this when I try {{279842187__value__list}} not the actual values found. So that fails to filter anything.
I believe the Get List Values action event may be a solution but there is a field called Item Format that has no clear instructions anywhere on what should be entered. Whatever I put in that field is the output when I test the step.

Does anyone have any insight into what this input may be looking for?
