[REQUIRED] Describe the problem

Upon user creation with email and password, the returned user is NULL and NO error message thrown! However, when checking the backend, the user is created successfully.

Relevant Code:

In the code below, "User credentials" and "currentUser" are both undefined and null respectively. I tried using firebase.auth().onAuthStateChanged, same result, the returned user is NULL.

User credentials: Object { "additionalUserInfo": wg { "isNewUser": true, "providerId": "password", }, "credential": null, "operationType": "signIn", "user": null, }


try {
  await firebase.default
    .auth()
    .createUserWithEmailAndPassword(email, password)
    .then((userCredential) => {
      console.log(
        "User credentials:",
        userCredential.user,
        "Current user:",
        firebase.default.auth().currentUser
      );
    })
    .catch((error) => {
      console.error("Error adding user:", error.code, error.message);
    });
} catch (err) {
  console.log(err);
}
