Hi Bruno,
In order to debug a module, you need to indicate the correct Entry module:

If you're trying to debug an action that starts on a screen, this should be the module producer of the Screen where you start the action.
If you're trying to debug an API, a Timer or a BPT, then this should be the module producer of the API / Timer / BPT.
You can read in more detail here.
Hope it helps.
Regards,
João
