Issue with user email required error returning 200 response with error in body

I have an issue with checking if a user has their email verified during the post-login action. I have added this in the post-login script:

exports.onExecutePostLogin = async (event, api) => {
    const axios = require("axios");
    const crypto = require("crypto");

    if (!event.user.email_verified) {
        console.log('User email is not verified 1');
        api.access.deny(`Please verify your email before logging in.`);
        return;
    }
    console.log('after verified')

    if (event.user.app_metadata.user_email_verification_sync) {
      return;
    }

    try {
        const url = event.secrets.MY+DOMAIN+"/api/v1/auth0/post-login-email-validation";

        const data = { email: event.user.email };

        const hash = crypto.createHash("sha256").update(event.user.email+event.secrets.MY_SECRET, "binary").digest("hex")
        const config = { headers: {'my-header': hash} };

        let response = await axios.post(url, data, config);
        
        if (response.status === 200) {
          api.user.setAppMetadata("user_email_verification_sync", true);
        }
    } catch (error) {
        // debbuging
        console.log(error.response.data.error);
    }
};

However, it is not working correctly. For some reason, this still returns a 200 response and logins/redirects my user. If someone knows what should be done here to return an error code, I would be grateful.

Another solution could be checking the success response in the login logic, but unfortunately, I haven’t been able to access it. The user is just logged in without any console logs triggering.

This is my login logic:

const login = (e) => {
  e.preventDefault();
  loginSubmitButton.classList = "mui-button loading";
  webAuth.login(
    {
      realm: databaseConnection,
      username: username.value,
      password: loginPassword.value,
    },
    function (err, authResult) {
      console.log("response is: ", { err, authResult });
      // Need to do aditional check here for authResult => to check if response is 200 and inside body error for email not verified
      loginSubmitButton.classList = "mui-button";
    }
  );
};

Any help would be greatly appreciated.
