Passport Authentication Callback Hangs

After hours trying to solve this by myself I reach to SO community looking for some light. I'm using passport for user authentication. It's already initialized in my main express.j

Solution 1:

If you're a noob to passport/express like me, this may help:

check if you invoke done() in your passport logic:

passport.use(new twitchStrategy({
    clientID: config.twitchID,
    clientSecret: config.twitchSecret,
    /*to be updated*/
    callbackURL: config.callbackURL,
    scope: "user_read"
  },
  function(accessToken, refreshToken, profile, done) {
    console.log(profile);
    ***return done();***
  }
));

Solution 2:

I see a few possible missing pieces glancing at my code. Are you using the passport.session() middleware? Also the serializeUser and deserializeUser functions?

passport.serializeUser(function(user, done) {
  //place user's id in cookie
  done(null, user.id);
});

passport.deserializeUser(function(id, done) {
  //retrieve user from database by id
  User.findById(id, function(err, user) {
    done(err, user);
  });
});
