Insert drafting views with details into a rvt file

Hello all,
I’m new to Dynamo (and I’m French … sorry for my english). I’ve been trying for a few days to insert detail views from a rvt file into a new rvt project. With the Rhythm package, I managed to insert the views into my new project but the elements inside have disappeared. With the help of @john_pierson, I tried a new script but it still does not work (see image below). I have the impression that he does not recognize my file in which I will look for my details … Thank you for your help!
