Node.js "passport-google-oauth2" delivers "failed to fetch user profile" error in Express application
While developing the last example of a node.js's introductory book (an express.js application using authentication strategy by Google OpenID), after replacing the passport-google package (which got obsolete on April 20th, 2015) with passport-google-oauth2 package (authentication strategy by Google OAuth 2.0) and having followed the indications at its documentation's page and an example here; I got the below error after selecting my Google+ account, which was thrown by the oath2.js module, concretely calling this._oauth2.get("https://www.googleapis.com/plus/v1/people/me",...) within userProfile(accessToken, done) method. The related source code and module dependencies are below.
What could be the root of the problem?
The concrete error is:
InternalOAuthError: failed to fetch user profile

profile.identifier=profile.id;
return done(null, profile);
}

Answer
I just fortunately found a similar issue at
jaredhanson/passport-google-oauth, which gave me the idea to go to the Google's project console and simply enable the Google+ API, which was "turned off" (oh me!!, naive developer of his first application based on Google+). That was the root of the problem. I tried again and the oauth2 started receiving profiles correctly.
