I've succeded to solve it.
The problem is in the .cfg file.
You must specify which body contains the interface. So you must change the
"gz_id" field with:
model_name::interface_name
and so not only interface_name.
I hope I helped you. If you have other problems or you haven't understood
me, please contact me.
