grpc_settings: get user_stettings does not seem to work properly ?

[markdoerr]

I cannot access GRPC_FRAMEWORK user settings properly (might be a bug in line 97 of your setting.py module):

I specified some user settings in my django settings file:

settings.py
GRPC_FRAMEWORK = { # 'ROOT_HANDLERS_HOOK': 'handlers.grpc_handlers', 'GRPC_HANDLERS': [] }
but when I try to retrieve the user settings:
from django_grpc_framework.settings import grpc_settings print(grpc_settings.GRPC_HANDLERS)

I get the expected error:
print(grpc_settings.GRPC_HANDLERS) File "/home/mark/py3venv/lara10/lib/python3.9/site-packages/django_grpc_framework/settings.py", line 93, in __getattr__ raise AttributeError("Invalid gRPC setting: '%s'" % attr) AttributeError: Invalid gRPC setting: 'GRPC_HANDLERS'

but it will not search in the self._user_settings

I think, there is an underscore missing in line 97 of django_grpc_framework/settings.py:
It should probably read:
try: # Check if present in user settings **val = self._user_settings[attr]**

I would be happy, if you could resolve the bug soon - or update the documentation on the correct way of adding user settings.
Thanks a lot !
