You commented out the GROUP on line 7 while you are using it on line 29. As a result you are passing blank GROUP to the gunicorn, same goes for USER, if you do not want to change the default USER or GROUP, then do not pass it to the gunicorn.

From docs:

A valid group id (as an integer) or the name of a user that can be retrieved with a call to pwd.getgrnam(value) or None to not change the worker processes group.
