Invalid scope error from oauth2 when starting up new bot

[austinvalle]

When starting up a new bot, I get this message when trying to retrieve the authentication token:

400 That's an error Error: invalid_scope Request Details scope=https://www.google.com/accounts/OAuthLogin response_type=code redirect_uri=urn:ietf:wg:oauth:2.0:oob client_id=936475272427.apps.googleusercontent.com

Existing bots have not been affected as of right now.

It looks like the issue also exists in the library (hangups) that hangupsjs was ported from, and is a result of some recent internal Google changes.
