Linkedin Callback Issue

[Terence Liu]

Hello Everyone,

I am trying to authenticate linkedin but I ran into an issue after the login popup:

Cannot GET /auth/linkedin/callback?code=AQRIx85ZlniIZwUPUZDNHl8XuXwxtY_Y5x0SDLSYQLqEaAp-s4SeQxkDbW9O4FT2GQiacdHITFO_kay5ZKepS4cy2YfSju9PlEfp6VKsf87jwTxYjwM&state=RoTe20G5HHEiSdG0Hk5Cldbw

I figure it would be a problem somewhere in the routes.js file, here are the codes related to the linkedin authentication posted below.

I thank you in advance for helping me, this is the first time I post an issue!

Sincerely,
Terence

// linkedin ---------------------------------

    // send to linkedin to do the authentication
    app.get('/auth/linkedin', passport.authenticate('linkedin', { scope: [ 'r_emailaddress', 'r_basicprofile']}));

    // handle the callback after linkedin has authenticated the user
    app.get('auth/linkedin/callback',
        passport.authenticate('linkedin', {
            successRedirect : '/profile',
            failureRedirect : '/'
        }));

// Linkedin ---------------------------------

    // send to linkedin to do the authentication
    app.get('/connect/linkedin', passport.authorize('linkedin' , { scope: [ 'r_emailaddress', 'r_basicprofile']}));

    // handle the callback after linkedin has authorized the user
    app.get('connect/linkedin/callback', 
        passport.authorize('linkedin', {
            successRedirect : '/profile',
            failureRedirect : '/'
        }));
