Hello Vaddi,
my personal experience: debugging with python doesn't work as good as intended, at least at the beginning. I would recommend you to try debugging just using the python window (F4). Just copy part of your macro until your "break point" and let SL execute it. Easy, quick.
If your macro contains relative paths, just use pwd/cd to set the reference folder and it will work.
I copy you two slides from our material. I hope it will help you.
In case you really need to link compose, just let us know.
