Hi All,
I am using Ionic2 with the Ionic native Facebook api in order to authenticate a user on Firebase.
loginFacebookCordova(): Promise<FirebaseAuthState> {
return new Promise<FirebaseAuthState>((resolve) => {
Facebook.login(['public_profile', 'email']).then(facebookData => {
let cred: firebase.auth.AuthCredential = firebase.auth.FacebookAuthProvider.credential(facebookData.authResponse.accessToken);
firebase.auth().signInWithCredential(cred).then((data: FirebaseAuthState) => {
resolve(data);
});
}, error => {
this.loading.dismiss();
console.error('loginFacebook: ' + error);
this.doAlert('Login with Facebook: ' + error.message);
}).catch((error) => {
this.loading.dismiss();
console.error('loginFacebook: ' + error);
this.doAlert('Login with Facebook: ' + error.message);
});
});
}
This works fine and I can create a registerd user on Firebase.
Problem
If I first create a user using GooglePlus (with the same email address), then log out. And try login with Facebook, then it just hangs, with no error message.
Question
How do I login to via Facebook, but get proper error handling or warning messages?
