FilteredElementCollector for Revit Link

Revit API
1

Hi,
main goal
I want to use the FilteredElementCollector in order to collect elements in my project and within the Links in my project.

My problem
My question is how do I collect only the elements that are in my current view?
Im not sure about what I tried because I am working on a big file with multiple Revit Links and when I try to print the elements I get an endless list of elements inside every Link, which doesnt seem right given the fact that my current view is a section with not a lot of elements in it.

link_doc.ActiveView.Id gets a NoneType error…
But when not passing an active view I get that endless list of elements I mentioned

My script

#######################################
# VARIABLES
#######################################
doc           = __revit__.ActiveUIDocument.Document     # type: Document
uidoc         = __revit__.ActiveUIDocument              # type: UIDocument
selection     = uidoc.Selection                         # type: Selection
#######################################
# MAIN
#######################################


# Collect all Revit Links instances
revit_link_instances_collector = FilteredElementCollector(doc, active_view.Id).OfClass(RevitLinkInstance).ToElements()
for link in revit_link_instances_collector:
    # Get the doc for current Link
    link_doc = link.GetLinkDocument()
    if link_doc:
        # collect all FamilyInstances
        linked_elemens = FilteredElementCollector(link_doc, link_doc.ActiveView.Id).OfClass(FamilyInstance).WhereElementIsNotElementType().ToElements()
        for element in linked_elemens:
            print(element)

link_doc.ActiveView.Id this call doesn’t work for pre-Revit 2024 API inside of FIlteredElementCollector

I save my active view in a variable like this:
activeView = doc.ActiveView
This way you only work with elements visible in your current active view
