[Ionic 4] Facebook connect problem


I’m using ionic 4 and i implemented the facebook connexion using the Facebook pluggin.
My problem is when i first click in the facebook login, it shows the facebook popup “continue as …” then no result is returned back by Facebook.
But if i click the second time in the button, i get back the result.
Is there any one facing the same problem.
This is a snippet of my code :

facebookConnect() {
this.fb.login([‘email’, ‘public_profile’]).then((response: FacebookLoginResponse) => {
this.reponseFb = response;
this.fb.api(‘me?fields=id,name,email’, ).then(profile => {
this.userData = {
email: profile[‘email’],
first_name: profile[‘first_name’],
username: profile[‘name’]
