Django "get_git_revision failed: [Errno 2] No such file or directory: '.../.git/HEAD'"

I recently installed pybrake for a Django app, and now when I run my development server, I see the following error:

2018-05-29 18:32:13,414 - pybrake - ERROR - get_git_revision failed: [Errno 2] No such file or directory: '/Users/kurtpeek/Documents/Dev/lucy2/lucy-web/.git/HEAD'

After that, however, the development server seems to start up normally; here is the full terminal response:

(venv) Kurts-MacBook-Pro-2:lucy-web kurtpeek$ python manage.py runserver
2018-05-29 18:32:13,414 - pybrake - ERROR - get_git_revision failed: [Errno 2] No such file or directory: '/Users/kurtpeek/Documents/Dev/lucy2/lucy-web/.git/HEAD'

Django version 1.11.9, using settings 'lucy.settings.development'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

The error still irks me a bit though and I'd like to remove it. It seems like this get_git_revision function is looking in the wrong directory: the .git directory is located in lucy2, not in lucy2/lucy-web.

However, I actually was unable to figure out where this error is coming from: I did a project-wide search for get_git_revision but didn't find anything. How can I figure out the source of this error?

As suggested by the formatting of the error message, the error is actually thrown by pybrake itself. By inspecting the source code (https://github.com/airbrake/pybrake/blob/master/pybrake/notifier.py), I found that it is possible to pass an (undocumented) root_directory key to the AIRBRAKE setting, like so:

AIRBRAKE = dict(
    project_id=os.getenv('AIRBRAKE_API_KEY'),
    project_key=os.getenv('AIRBRAKE_PROJECT_ID'),
    root_directory=os.path.dirname(os.path.dirname(BASE_DIR)))

where the root_directory is appropriately selected to contain the .git directory. Now I can run the development server without errors:

(venv) Kurts-MacBook-Pro-2:lucy-web kurtpeek$ python manage.py runserver

Quit the server with CONTROL-C.

Incidentally, os.path.dirname(os.getcwd()) would also work here, as it goes one directory up from pybrake's default, os.getcwd().
