Error when no SELENIUM_DRIVER_ARGUEMNTS are set in settings.py

[nacer-benyoub]

When no SELENIUM_DRIVER_ARGUEMNTS are set in settings.py, the error TypeError: 'NoneType' object is not iterable is raised. This should be a simple fix in middleware.py by adding:

if driver_arguments is not None:
    for argument in driver_arguments:
        driver_options.add_argument(argument)

Instead of iterating directly on driver_arguments.
