Google Oauth2 userinfo API not returning user's name data

Question

For the past couple months I have been using this url to retrieve a user's name and info after logging in with OAuth.

    https://www.googleapis.com/oauth2/v1/userinfo?alt=json

This gave me JSON in the following format:

    {
      "id": "12345",
      "email": "name@gmail.com",
      "verified_email": true,
      "name": "First Last",
      "given_name": "First",
      "family_name": "Last",
      "link": "https://plus.google.com/12345",
      "picture": "https://lh3.googleusercontent.com/123photo.jpg",
      "locale": "en"
    }

This morning, when my app hit this endpoint, it got JSON in the following format:

    {
      "id": "12345",
      "email": "name@gmail.com",
      "verified_email": true,
      "picture": "https://lh3.googleusercontent.com/123/photo.jpg"
    }

I have not made any changes to the configuration in the developer console. Does anyone know what the cause of this problem could be?

Bschweer, have you checked my answer? Did it help or did you solve the problem in some other way? — Ján Halaša, Jun 04 '19 at 06:21
Ján, I was able to solve this by updating the scope. My previous settings were working fine until the beginning of April. I do think the shutdown of Google+ had something to do with my issue. — bschweer, Jun 05 '19 at 17:03

I think you should use a different URL - the one from OpenID Connect, which is an OAuth2 extension for authentication and the userinfo endpoint is specified in its RFC.

https://openidconnect.googleapis.com/v1/userinfo

The correct procedure is to get this URL from the OpenID Discovery document (Google doc)

https://accounts.google.com/.well-known/openid-configuration

and its userinfo_endpoint attribute.

The change of behavior of the endpoint you have been using may have something to do with Google+ being shut down. But that's just my guess.
