Passport-Facebook authentication is not providing email for all Facebook accounts

Question

I am using Passport-Facebook authentication.

  passport.use(new FacebookStrategy({
            clientID: \'CLIENT_ID\',
            clientSecret: \'CLIENT_SECRET\         


        

Answer 1

Make sure you're providing the scope parameter into the first .authenticate() call, not the callback.

Like this:

router.get("/auth/facebook", passport.authenticate("facebook", {
    scope: [ "email" ], // scope goes here, not below
}));

router.get("/auth/facebook/callback",
    passport.authenticate("facebook", {
        successRedirect: "/",
        failureRedirect: "/login",
    }),
);
