OneLogin error in get_group_members

I'm trying to use OneLogin settings but during the service initialization, I'm receiving this error below:

Traceback (most recent call last):
  File "/opt/github-team-sync/app.py", line 113, in directory_group_members
    members = directory.get_group_members(group_name=group)
  File "/opt/github-team-sync/githubapp/onelogin.py", line 21, in get_group_members
    users = self.client.get_users(query_parameters={"role_id": role[0].id})
TypeError: 'NoneType' object is not subscriptable

    raise KeyError(key) from None
