AdaptiveComponent.Locations return empty list

I try to get adaptive component location with AdaptiveComponent.Locations, but I got an empty list. I saw some tutorial that used this node. Is it any problem or bug with dynamo 2.2. I use Revit 2022.1.
Thank you

Could you drop dummy rvt file here to test?

Looks good to me:

Silly question but do your adaptive component family have adaptive points in them?

Thank you, here is my revit file

I think I found the problem. I place my adaptive in my model in-place so I cannot get those objects in the top level. Anyway thank you for your response
