firebase sendEmailVerification does not give error on non exisent email address

I'm developing an authentication system for my React app with Firebase Auth. When the user signs up, firebase auth registers the user (createUserWithEmailAndPassword) and returns a promise with auth.uid and auth.emailVerified set to "false". This is fine.

I then use sendEmailVerification() method so the email address can be verified. I've tested the code and it works ok for a "valid" and "existing" email address. "catch" does give error for duplicate email address as expected. The problem is, it does not send the NON-EXISTING email (which I suppose is the correct bahaviour) but its should then give an error (so I can display to the user) which it does not.

Can someone explain why I'm not getting error for NON EXISTENT email address?

export const unpSignUp = (newUser) => {
    console.log("newUser", newUser);
    return (dispatch, getState, { getFirebase, getFirestore }) => {
        const firebase = getFirebase();
        const firestore = getFirestore();
        firebase.auth().createUserWithEmailAndPassword(
        newUser.unp_a05_email,
        newUser.unp_a10_password
        )
        .then((response) => {
        return firestore
            .collection("unps")
            .doc(response.user.uid)
            .set({
                unp_a02_surname: newUser.unp_a02_surname,
                unp_a03_name: newUser.unp_a03_name,
                unp_a06_verify_email_sent_datetime: null,
                unp_a07_email_verified_on_datetime: null,
                unp_a18_acc_created_on_datetime: moment().format("YYYY MM DD HH:mm:ss"),
            });
        })
            .then((response) => {
            console.log("SIGNUP SUCCESS ", response);
            // user has been signed up, next step is to send verification email
            dispatch({ type: SIGNUP_SUCCESS })
        })
        .then(() => {
            // user has been signed up, next step is to send verification email
            console.log('send email adr verification')
            return firebase.auth().currentUser.sendEmailVerification()
        })
        .then( (response) => {
            console.log("Verification email sent", response);
            const user = firebase.auth().currentUser
            console.log('current user', user)
            const unp = firestore.collection("unps").doc(user.uid);
            return unp.update({
            unp_a06_verify_email_sent_datetime: moment().format("YYYY MM DD HH:mm:ss"),
            })
        })
        .then( () => {
            console.log(`unp_a06_verify_email_sent_datetime update to ${moment().format("YYYY MM DD HH:mm:ss")} `)
        })
        .catch((error) => {
            console.log("SIGNUP ERROR", error);
            console.log("SIGNUP ERROR CODE", error.code);
            console.log("SIGNUP ERROR MESAGE", error.message);
            dispatch({ type: SIGNUP_ERROR, error });
        });
    };
};

From firebase reference,

the return type of sendEmailVerification is Promise<void> - and it does not tell about any error codes that are sent in case of wrong email or failed/bounce mails. The error code it mentions is with respect to actionCodeSettings

If the actionCodeSettings is not specified, no URL is appended to the action URL. The state URL provided must belong to a domain that is whitelisted by the developer in the console. Otherwise an error will be thrown.

Thus it can not be checked if it is a valid email id. (This is expected behaviour as receiving mail servers may be down at times and hence there is a concept of retrying bounce mails)
