Allow clients to debug code from command line, like pdb or epdb

Comienza con debugpy/main.py y server/cli.py, y luego sigue la ruta indicada a través de server/api.py y los archivos pydevd incluidos como vendor. Reproduce el fallo de OutputEvent/command y determina si se admite la depuración desde la línea de comandos y en el shell interactivo. Se considerará terminado cuando un flujo de trabajo acordado desde la línea de comandos funcione sin este fallo y su uso esté documentado.

Hi there,
in my company many don't use VSCode. For this reason our main guidelines to debug are to use pdb or epdb. (https://pypi.org/project/epdb/)
However, in an effort to have just one library that works for all use cases, I'd like to have debugpy to work from command line too.

I have tried this:

python -m debugpy --connect 5678 <path of the file with debugpy.listen()>

doesn't stop in debug.

I've also tried to use debugpy in python shell:

>>> import debugpy
>>> debugpy.connect(5678)

    method_name = 'on_%s_request' % (request.command.lower(),)
AttributeError: 'OutputEvent' object has no attribute 'command'

What is supposed to be this "command"?

Also, am I doing something that is intended to be used like this, or what? I think no, because there is no such reference on the web.
