You are attempting to use the Google auth backend, but it is not properly configured. To configure, please check the following:

• You have created a Google OAuth2 client and enabled the Identity Toolkit API. You can create OAuth2 apps at the Google developer console.
• You have configured your OAuth2 client to allow redirects to your server’s Google auth URL: {{ root_domain_url }}/complete/google/.
• You have set {{ client_id_key_name }} in {{ settings_path }} and social_auth_google_secret in {{ secrets_path }}.
• Navigate back to the login page and attempt the Google auth flow again.
