What happened:
After following all the requirements as specified in the docs for setting up security via google_auth: https://airflow.apache.org/docs/apache-airflow/1.10.14/security.html#google-authentication, the following command throws an error

What you expected to happen:
I expect the configurations to be listed without throwing an error.

How to reproduce it:
You can reproduce this on a clean install of airflow or using the official airflow docker image.

Run:
pip install 'apache-airflow[google_auth]'

Add the following to airflow.cfg file:

[google]
client_id = google_client_id
client_secret = google_client_secret
oauth_callback_route = /oauth2callback
domain = example1.com,example2.com
prompt = <One of : consent, select_account, none or ''>

Then run the following command from the cli:

airflow config list
