[TypeError: Parameter 'url' must be a string, not undefined] in users.oauthCallback

[igorauad]

Does anybody have a clue on the following error, obtained inside users.oauthCallback when using LinkedIn authentication?

[TypeError: Parameter 'url' must be a string, not undefined]

Here is my strategy configuration:

// Use linkedin strategy
passport.use(new LinkedInStrategy({
        consumerKey: config.linkedin.clientID,
        consumerSecret: config.linkedin.clientSecret,
        callbackURL: config.linkedin.callbackURL,
        passReqToCallback: true,
        profileFields: ['id', 'first-name', 'last-name', 'email-address', 'picture-url', 'public-profile-url']
    },
    function(req, accessToken, refreshToken, profile, done) {

        // Set the provider data and include tokens
        var providerData = profile._json;
        providerData.accessToken = accessToken;
        providerData.refreshToken = refreshToken;

        // Create the user OAuth profile
        var providerUserProfile = {
            firstName: profile.name.givenName,
            lastName: profile.name.familyName,
            displayName: profile.displayName,
            email: profile.emails[0].value,
            provider: 'linkedin',
            providerIdentifierField: 'id',
            providerData: providerData
        };

        // Save the user OAuth profile
        auth.saveOAuthUserProfile(req, providerUserProfile, done);
    }
));

I tried to find where the error comes from, but haven't had success....
