userinfo endpoint is depreciated.

The userinfo endpoint is depreciated as per google login scopes documentation: https://developers.google.com/+/api/oauth#login-scopes and https://developers.google.com/+/api/auth-migration#timetable

It's not currently possible to migrate to using email & profile because the format_scope method is too restrictive and always prepends https://www.googleapis.com/auth/ to passed scopes

Thanks for this. I'll modify the format_scope and get it working as per the documentation
