DUO-LABS WebAuthn: Ошибка проверки учетных данных сервером: ошибка регистрации. ошибка: регистрация отклонена. ошибка: невозможно проверить происхождение

Я попытался реализовать аутентификацию на основе отпечатков пальцев с помощью пакета Python DUO-lab webauthn. Однако я столкнулся с этой ошибкой:

server validation of credential failed: registration failed. error: registration rejected. error: unable to verify origin..

Когда я проверил исходный код пакета, я заметил, что эта ошибка unable to verify origin.. возникла, когда, возможно, ваш аутентификатор был неправильно настроен.

Могу ли я конкретно указать, что мне нужны только аутентификаторы platform, а не roaming, не загромождая исходный код пакета? Если есть, пожалуйста, включите полный рабочий код для Flask (это то, что я использую сейчас после того, как ошибка выгнала меня из Django). Мои текущие конфигурации:

RP_ID = 'nacesdecide.herokuapp.com' #The app is currently hosted on heroku
RP_NAME = 'nacesdecides nacesdecide'
ORIGIN = 'https://nacesdecide.herokuapp.com/'

Приложение в настоящее время находится на сайте heroku, и к нему можно получить доступ в режиме реального времени через регистр naces. Я хочу, чтобы приложение использовало только platform authenticators.

Обновление:

Некоторая часть кода на стороне клиента (взято из python webauthn flask demon js от duo-lab:

/**
 * REGISTRATION FUNCTIONS
 */

/**
 * Callback after the registration form is submitted.
 * @param {Event} e
 */
const didClickRegister = async (e) => {
  e.preventDefault();

  // gather the data in the form
  const form = document.querySelector("#register-form");
  const formData = new FormData(form);

  // post the data to the server to generate the PublicKeyCredentialCreateOptions
  let credentialCreateOptionsFromServer;
  try {
    credentialCreateOptionsFromServer = await getCredentialCreateOptionsFromServer(
      formData
    );
  } catch (err) {
    showErrorAlert(`Failed to generate credential request options: ${err}`);
    return console.error("Failed to generate credential request options:", err);
  }

  // convert certain members of the PublicKeyCredentialCreateOptions into
  // byte arrays as expected by the spec.
  const publicKeyCredentialCreateOptions = transformCredentialCreateOptions(
    credentialCreateOptionsFromServer
  );

  // request the authenticator(s) to create a new credential keypair.
  let credential;
  *try {
    credential = await navigator.credentials.create({
      publicKey: publicKeyCredentialCreateOptions,
    });*
  } catch (err) {
    showErrorAlert(`Error creating credential: ${err}`);
    return console.error("Error creating credential:", err);
  }

  // we now have a new credential! We now need to encode the byte arrays
  // in the credential into strings, for posting to our server.
  const newAssertionForServer = transformNewAssertionForServer(credential);

  // post the transformed credential data to the server for validation
  // and storing the public key
  let assertionValidationResponse;
  try {
    assertionValidationResponse = await postNewAssertionToServer(
      newAssertionForServer
    );
  } catch (err) {
    showErrorAlert(`Server validation of credential failed: ${err}`);
    return console.error("Server validation of credential failed:", err);
  }

  // reload the page after a successful result
  setTimeout(function () {
    window.location.href = Flask.url_for("accounts.login");
  }, 1000);
  //   window.location.reload();
};

На стороне сервера у нас есть:

def webauthn_begin_activate():
    # MakeCredentialOptions
    username = request.form.get('register_username')
    display_name = request.form.get('register_display_name')

    if not util.validate_username(username):
        return make_response(jsonify({'fail': 'Invalid username.'}), 401)
    if not util.validate_display_name(display_name):
        return make_response(jsonify({'fail': 'Invalid display name.'}), 401)

    if User.query.filter_by(username=username).first():
        return make_response(jsonify({'fail': 'User already exists.'}), 401)

    #clear session variables prior to starting a new registration
    session.pop('register_ukey', None)
    session.pop('register_username', None)
    session.pop('register_display_name', None)
    session.pop('challenge', None)

    session['register_username'] = username
    session['register_display_name'] = display_name

    challenge = util.generate_challenge(32)
    ukey = util.generate_ukey()

    # We strip the saved challenge of padding, so that we can do a byte
    # comparison on the URL-safe-without-padding challenge we get back
    # from the browser.
    # We will still pass the padded version down to the browser so that the JS
    # can decode the challenge into binary without too much trouble.
    session['challenge'] = challenge.rstrip('=')
    session['register_ukey'] = ukey

    *make_credential_options = webauthn.WebAuthnMakeCredentialOptions(
        challenge, RP_NAME, RP_ID, ukey, username, display_name,
        'https://example.com')*

    return jsonify(make_credential_options.registration_dict)

    credential_id_exists = User.query.filter_by(
