Describe the problem
getRedirectResult always returns null on emulator. The same code works without using the emulator (on Android, that is. On MacOS Safari it doesn't work with or without emulator, but that's a separate issue).
Steps and code to reproduce issue
Code is very simple. It tries to get the redirect result first, which fails the first time and calls signInWithRedirect. Second time getRedirectResult is supposed to return a user credential, not null.
const app = initializeApp(firebaseConfig);
const auth = getAuth();
connectAuthEmulator(auth, "http://127.0.0.1:9099");
const provider = new GoogleAuthProvider();
provider.addScope('https://www.googleapis.com/auth/contacts.readonly');
provider.setCustomParameters({
'login_hint': 'user@example.com'
});
try {
console.log("before redirect");
let userCredential = await getRedirectResult(auth);
if (userCredential) {
const user = userCredential.user;
console.log("==USER==");
console.log(user);
const credential = GoogleAuthProvider.credentialFromResult(userCredential);
console.log("==CREDENTIAL==");
console.log(credential);
const token = credential.accessToken;
console.log("==TOKEN==");
console.log(token);
} else {
console.log("NO RESULT");
await signInWithRedirect(auth, provider);
}
} catch(error) {
console.error(error);
}
