Missing required parameter: redirect_uri with passport-google-oauth

Question

Using passport-google-oauth: "0.2.0" in my MEAN Stack application (found here: https://github.com/jaredhanson/passport-google-oauth). When I run the application and attempt to sign in with a Google API this error is returned

400. That’s an error.

Error: invalid_request

Missing required parameter: redirect_uri

Request Details scope=https://www.googleapis.com/auth/plus.login response_type=code redirect_uri= client_id=xxxx-xxxx.apps.googleusercontent.com

The redirect param is here passport-init.js

var GoogleStrategy = require('passport-google-oauth').OAuth2Strategy;

var GOOGLE_CLIENT_ID = "xxx-xxx.apps.googleusercontent.com"; var GOOGLE_CLIENT_SECRET = "xxxx";

passport.use(new GoogleStrategy({
clientID: GOOGLE_CLIENT_ID,
clientSecret: GOOGLE_CLIENT_SECRET,
callbackUrl: "http://127.0.0.1:3000/auth/google/oauth2callback" }, function(accessToken, refreshToken, profile, done){ done(null,profile); } ));

The routes are here authenticate.js

router.get('/google', passport.authenticate('google', { scope: ['https://www.googleapis.com/auth/plus.login']}), function (req, res){ });

router.get('/google/oauth2callback', passport.authenticate('google', { successRedirect: '/auth/success', failureRedirect: '/auth/failure' }) , function (req, res) {res.redirect('/');} );

I am sure I am missing something simple, but I don't know what to add in this question that will give you the best information. Please ask and I will do my best to answer you. This is what feels like the pertinent data.

Funny thing is if I add the callbackUrl manually then everything works great. I can reach the Google API fine. Then I am given the choice to "allow" or "deny" the request.

Answer 1

When defining the GoogleStrategy, the JSON key should be callbackURL instead of callbackUrl (i.e., capital URL). Had this 'issue' as well ;-)
