Answer questions karthiknadig

@m0tz There were two issues:

  1. "program": should point to a python file. The Python extension picks up the executable based on the version of python selected via the interpreter selection UI. In your setting it was pointing to a directory (your workspace folder).
  2. "args": are a list of arguments that you pass to your python script or module. In your case the args were [ "python", "", "runserver_plus"]. This is equivalent to: /usr/bin/python python runserver_plus. See python is there twice, this causes the debugger to try to load python.__main__.

How did you find the debug config that you used?
