Селектор Google captcha DOM не работает - document.querySelector ('# g-captcha-response'). Value

Question

При обращении к селектору для gapaptcha значение из g-captcha-response ВСЕГДА пусто.Это работало ранее, но внезапно прекратилось.В настоящее время я использую vue, а функции капчи и регистра находятся внутри компонента.Я не сделал абсолютно никаких изменений или изменений в коде, ответственном за проверку / регистрацию.Я очень потерян и очень отчаялся.

register() {
  var username = this.username;
  var password = this.password;
  var email = this.email;
  var password_again = this.password;
  var referral = this.referral;
  var captcha = document.querySelector("#g-recaptcha-response").value;


  // set loading state
  this.loading = true;

  let pattern = /^[0-9a-zA-Z]+$/;
  // check if username is not alphanumeric
  if (!this.username.match(pattern)) {
    return alert('Your username can not contain any non-alphanumeric characters');
  }

  // if passwords don't match
  if (password !== password_again) {
    return alert('Your passwords do not match');
  }

  console.log('CAPTCHA RESPONSE');
  console.log(captcha);

  return; /** End here */

  this.$http({
    method: 'POST',
    url: api.dev + 'api/v1/register',
    data: {
      username,
      email,
      password,
      password_again: this.password,
      referral,
      captcha: captcha
    }
  }).then(res => {
    console.log(res.data);
    if (res.data.success == true) {
      this.success = true;
      setTimeout(() => {
        $("#registerModal").modal('toggle');
        $('#loginModal').modal('toggle');
        this.success = false;
        this.error = "";
      }, 1200)
      return;
    } else {
      this.error = res.data.message
      this.loading = false;
    }


  })
}
