email is not returned

[ashnamuh]

Hi,

I'm using nodejs and expressjs with passport-facebook for user to signup account with fb account. I found a facebook user account is not returning the email. The user don't signed up with the Phone number instead. Only email is saved in the account contact. In addition, the email has been verified. I don't know what is problem. Anyone has an idea?

My strategy

passport.use(new FacebookStrategy({
  clientID: facebookConfig.clientID,
  clientSecret: facebookConfig.clientSecret,
  callbackURL: facebookConfig.callbackURL,
  profileFields: ['id', 'displayName', 'name', 'gender', 'profileUrl', 'emails', 'photos'] // also 'email' is not working
  },
  function facebookHandler(accessToken, refreshToken, profile, cb) {
    if (!profile.emails || !profile.emails[0].value || !profile._json.email) {
      throw new UnprocessableEntity('No Email in Facebook');
    }
    let email = profile.emails[0].value || profile._json.email;

    User.findOne({
      where: {externalId: profile.id}
    })
    ...
  }
));

+1 here. Same issue. Tried using 'email' and 'emails'. Nothing gets returned.

You need to do the following when authenticating: passport.authenticate('facebook', {scope: 'email'}) Then, in your FacebookStrategy, request profileFields: [...'email'...]

Hi, I am having the same issue. Please see my code below. Not being able to request additional permissions... Any suggestions?

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

passport.use(new FacebookStrategy({ clientID: ///// clientSecret: //// callbackURL: "http://localhost:8000/auth/facebook/callback", profileFields: ['id', 'email', 'displayName', 'photos'] },

+1, requesting both in scope

passport.authenticate("facebook", {
   failureRedirect: "/login",
   scope: ["email"] ...

and profileFields:

profileFields: ['id', 'email', 'name'] ...

After checking the official facebook APIs, it seems that passport is broken.. or there's something I don't get.

Here's a working url created by hand using the facebook docs (paste it in the browser adding your app id and you'll see the popup):

https://www.facebook.com/v2.8/dialog/oauth?client_id=your_app_id&redirect_uri=http://localhost:3000/auth/facebook/callback&scope=public_profile,email

And here's the url that passportjs generates (passing scope: ["public_profile", "email"] ) :

https://www.facebook.com/dialog/oauth?response_type=code&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fauth%2Ffacebook%2Fcallback&client_id=your_app_id

Clearly the scope doesn't get appended to the url, now we should investigate why and what's the right way to add scope to the request. .. maybe looking at the passport.authenticate() function in the source code could help?

@rsnider19 do you know something more?

I used the following and it worked:

passport.use(new FacebookStrategy({
  clientId: ...,
  clientSecret: ...,
  callbackURL: ....,
  profileFields: ['id', 'displayName', 'email', 'first_name', 'middle_name', 'last_name']
}))

I tried the following, and it is still not working.

1. add email to scope passport.authenticate('facebook', { scope : ['email', 'public_profile'], session : false }),

2. add email to profileFields profileFields: ["id", "birthday", "email", "first_name", "last_name", "gender", "picture.width(200).height(200)"],

When I tried the Graph API V 2.7 with me?fields=id,name,email, email is also not returned.

Try it

passport.use('facebook', new FacebookStrategy({
  clientID        : secret.facebook.clientID,
  clientSecret    : secret.facebook.clientSecret,
  callbackURL     : secret.facebook.callback,
  profileFields   : secret.facebook.profileFields
},

For me this happens when users have restricted the visibility of their email address to only themselves.

@rsnider19 , Thanks man your solution worked.

[amitfegade121]

@rsnider19 Thanks man... Your solution works..... Guys go for it.....

[MBerka]

The provided solutions (email in bot scope and in profileFields) work, and produce an object that looks just like the GoogleStrategy's. Any problems with the scope term missing from the URL (vyzen's post) appear resolved; it looked normal to me even when I was using the wrong scope strings. Recommend close.

You can use specified strings in this URL https://developers.facebook.com/docs/facebook-login/permissions#reference-default

Below is a snippet for strategy configuration

const { Strategy } = require('passport-facebook');
const FacebookStrategy = Strategy;

exports.facebookStrategy = new FacebookStrategy(
  {
    clientID: process.env.FACEBOOK_CLIENT_ID,
    clientSecret: process.env.FACEBOOK_CLIENT_SECRET,
    callbackURL: process.env.FACEBOOK_CALLBACK_URL,
    profileFields: [
      'email',
      'name',
      'displayName',
      'picture' ,
      'name_format',
      'short_name',
    ]
  },
  function(accessToken, refreshToken, profile, done) {
    done(null, profile);
  }
)

I'm facing the same and I guess when it happens is something related to the following documentation and not passport it self:

email | string | The User's primary email address listed on their profile. This field will not be returned if no valid email address is available. Facebook Graph API User

I've just implemented this as an alternative:

      const { email, first_name, last_name, id} = profile._json;
      const userData = {
        email: email || id, // If there's no e-mail, uses user's Facebook id
        nome: `${first_name} ${last_name}`,
      };

I don't like it. But I hope it works.

I used the following and it worked:

passport.use(new FacebookStrategy({
  clientId: ...,
  clientSecret: ...,
  callbackURL: ....,
  profileFields: ['id', 'displayName', 'email', 'first_name', 'middle_name', 'last_name']
}))

Works for me

May be you didn't added email in permision section of your meta developer console app.

Inside Meta developer console > go to your App > go to "Use Cases" > go to "Authentication and account creation customization "> in customiztion check the below "permisssion" section if email is added or not?
