How to apply my Revit model into Dynamo for Sunlight hours analysis?

I am a new user of Dynamo and I’m having some trouble to apply the sunlighthours analysis to my Revit model. I’ve watched @mostapha ‘Sunlight Hours Analysis in Dynamo’ video and everything worked fine, but now I’m not able to apply my model to this script. I’ve tried by using:
‘SelectModelElements’>‘ElementGeometry’>‘List’ but it’s giving me way too many warnings, and of course it’s not working.
I’ve done this same sunlight hours analysis many times with Grasshopper&Ladybug with no problems, but I can’t find the way to load my Revit massing into Dynamo and make it work.
Does anyone know how to solve this?

Thank you in advance.
