Model Element recognised as unknown element

Hey gang(
im rather new to dynamo. Am trying to create a script that allows me to duplicate a door ( hosted on a wall ) at the same position on multiple levels.

I started by identifying the door’s location, however im met with this error

Warning: FamilyInstance.Location expects argument type(s) (Revit.Elements.FamilyInstance), but was called with (Revit.Elements.UnknownElement).

Does anyone know why this happens?

Any help is much appreciated.

Kindest,
LL

can you show the element properties in the revit window?

After 8 hours of sleep it decided to work now…
