Firebase WEB - Unable to send email verification. Is the code the issue?

After attempting various methods to call the function sendEmailVerification(), I have not been successful. Even the documentation hasn't provided much help.

Here is a snippet of the source code that I am working with. Any guidance on how to address this issue would be greatly appreciated.

When checking my console, I encountered the following error:

TypeError: Cannot read property 'emailVerified' of null at Object.firebase.auth.onAuthStateChanged.firebaseUser [as next]

    btnSignUpWithGoogle.addEventListener('click', e => {
        var provider = new firebase.auth.GoogleAuthProvider();

        firebase.auth().signInWithPopup(provider).then(function(result) {
            var token = result.credential.accessToken;
            var user = result.user;
          }).catch(function(error) {
              var errorCode = error.code;
              var errorMessage = error.message;
              var email = error.email;
              var credential = error.credential;
              console.log(errorCode);
          });
    });

    // Other event listeners and their associated functions...

Do we have access to all the code? Have you double-checked that your firebase.auth() is properly declared?

Your authentication setup should resemble the following:

const firebaseApp = firebase.initializeApp(firebaseConfig, 'Client');
const firebaseAuth = firebaseApp.auth();

Make sure that firebaseUser includes an emailVerified key. Consider moving your if else statement inside the firebaseUser condition like this:

firebase.auth().onAuthStateChanged(firebaseUser => {
  if (firebaseUser) {
    console.log(firebaseUser);
    console.log('Logged IN!');
    btnLogout.style.visibility = 'visible';

    if (firebaseUser.emailVerified) {
      console.log('Email is verified');
    }
    else {
      console.log('Email is not verified');
      firebaseUser.sendEmailVerification();
    }

  }

});

After running console.log(firebaseUser), what does it output?
