Attempting to build a custom profile center in Marketing Cloud using Cloud Pages that uses SSJS to pull profile and preference attributes set in the default profile manager.
Using WSProxy I'm doing a 'describe' method on the Subscriber object, getting the JSON back with all of the possible profile attributes + the ExtendedProperties node which describes any custom attributes added to the profile center in SFMC.
When you create restricted values in the profile attribute creator, it shows up as a dropdown menu in the default profile center and in the JSON it declares it as IsRestrictedPicklist = True. The next pair in the JSON is an array of the picklist values called PicklistItems but they are always null when I parse the results.
"IsRestrictedPicklist": true, "PicklistItems": [ null, null, null ],
Does anyone know why would be showing up as null?
