web: Firebase authentication successful but returns a null user (Web)

I am having trouble authenticating users using firebase with my web application. Whenever I attempt a login the firebase.auth().signInWithEmailAndPassword(email, pass); function is called, the request is successful and the authStateChanged listener is triggered. However, inside the listener firebaseUser always returns null.

I have tried hosting the web application from a personal server and allowing the domain access to my firebase DB.

I also have an android application that works flawlessly with the same DB.

Here is my code:

(function() {

    // Initialize Firebase
      var config = {
        apiKey: "AIzaSyBtCBqqODTYrb1BxCOOyHRhrDboi7n6G4k",
        authDomain: "athlete-buddy.firebaseapp.com",
        databaseURL: "http://ift.tt/2l4B7G2",
        storageBucket: "athlete-buddy.appspot.com",
        messagingSenderId: "822225329435"
      };
      firebase.initializeApp(config);

      // Get elements

      const txtEmail = document.getElementById('username');
      const txtPassword = document.getElementById('password');
      const loginButton = document.getElementById('loginButton');

      loginButton.addEventListener('click', e => {

        const email = txtEmail.value;
        const pass = txtPassword.value;
        const auth = firebase.auth();

        const promise = auth.signInWithEmailAndPassword(email, pass);
        promise.catch(e => console.log(e.message));
      });

      firebase.auth().onAuthStateChanged(firebaseUser => {
        if(firebaseUser){
            console.log(firebaseUser);
        }
        else{
            console.log('not logged in');
        }
      })

}());
