FamilyInstance.ByFamilyType don't work

Here is the picture. I want to use the family types to choose the instances in Revit, but this notes do not work for the wall types or floor types.
Does anyone have anything ideas how to use this note.
Thanks in advance.

Walls and floors are system families so they won’t work with this node.
