Indoor Preliminary Pathways creation issue

[KayalvizhiK]

I was trying to create preliminary pathways with the floorplan I've created with indoors information model. While running the generate Indoor pathways tool, it executed successfully with few warnings. But there is no pathways generated or data populated in my PrelimPathway feature class. Can anyone help on what am I missing?

I would expect the detail expression to be something more like "('Interior Wall')" rather than "('Doors')" as doors are not going to be the barriers for your output.
