Email key is missing in the profile object in passportjs

[sarsarahman]

Trying to use Facebook authentication using passportjs on my mean application. But Email key is missing in the profile object

I am getting the following object

{
    id: '12345678901234567',
    username: undefined,
    displayName: 'Display Name',
    name: {
        familyName: undefined,
        givenName: undefined,
        middleName: undefined
    },
    gender: undefined,
    profileUrl: undefined,
    provider: 'facebook',
    _raw: '{"name":"Display Name","id":"12345678901234567"}',
    _json: {
        name: 'Display Name',
        id: '12345678901234567'
    }
}

here are the routes

    app.get('/auth/facebook', passport.authenticate('facebook', {
        scope: ['email']
    }));

    app.get('/auth/facebook/callback', passport.authenticate('facebook', {
        successRedirect: '/profile',
        failureRedirect: '/'
    }));

    app.get('/connect/facebook', passport.authorize('facebook', {
        scope: ['email']
    }));

    app.get('/connect/facebook/callback', passport.authorize('facebook', {
        successRedirect: '/profile',
        failureRedirect: '/'
    }));

here is the screenshot of my apps permission

what could be going wrong?

Try using the additional parameter profileFields while creating your strategy -

passport.use(new FacebookStrategy({
  clientID: FACEBOOK_APP_ID,
  clientSecret: FACEBOOK_APP_SECRET,
  callbackURL: "http://localhost:3000/auth/facebook/callback",
  profileFields: ['email']
    ....

This worked for me

@rohang07 : thanks for the solution, its also work for me.

@rohang07 this solution works the case for login , but when i try to register a user then issues appear which say bad gateway

[rohang07]

@KanwalPrakashSingh facebook registration with similar code works for me.
Internal server errors can be due to improper handling of the data which facebook returns (among infinitely many others). Try to log at a few places in your facebook strategy and see where exactly it fails. Any error (as simple and elusive as a null) there can cause such issues.

@rohang07
profileFields: ['email'] is the good answer
Thanks. It work for me.

..while creating your strategy 😄 then everything works as expected 😄

Now I'm getting the exact same issue. Even after trying the code that supposedly works. Perhaps it's because Facebook's oAuth is v2.6?

[ghost]

Yeah, it is. That code works fine with API v2.5 but not 2.6

[kevin-madhu]

It works in API v2.6 for me.
passport.use(new Strategy({
clientID: process.env.CLIENT_ID,
clientSecret: process.env.CLIENT_SECRET,
callbackURL: 'http://localhost:3000/login/facebook/return',
profileFields: ['id', 'email', 'gender', 'link', 'locale', 'name', 'timezone', 'updated_time', 'verified'],
enableProof: true
}, ...

See https://developers.facebook.com/docs/graph-api/securing-requests for details.

the solutions above didn't work for me, but with adding scope:["email"] it works 😁😁

{
    clientID: process.env.FACEBOOK_APP_ID,
    clientSecret: process.env.FACEBOOK_APP_SECRET,
    callbackURL: "http://localhost:3000/api/auth/facebook/callback",
    profileFields: ["email"],
    scope: ["email"],
    enableProof: true,
}
