GigyaAuthRequest->send() doesn't have proper exception validation

[stratulat-vladislav]

I have created a module which depends on gigya/drupal8 and I'm using the following API:

$responce = $helper->getGigyaApiHelper()->sendApiCall('accounts.unsubscribe', ['email' => '[email protected]']);
// validate $responce and do something else

This call is throwing the following error because there's no such email registered in Gigya and prevents my code to execute "validate $responce and do something else" part:

Drupal\gigya\CmsStarterKit\GSApiException: Invalid parameter value in Drupal\gigya\CmsStarterKit\GigyaAuthRequest->send() (line 49 of /Applications/MAMP/htdocs/di-tjx-ntw-d9/web/modules/contrib/gigya-drupal/gigya/src/CmsStarterKit/GigyaAuthRequest.php).

The error is the actual error response from Gigya, but it shouldn't block me from doing something else.
I believe the code of send() method should look something like this instead:

public function send($timeout = null) {
  try {
    $res = parent::send($timeout);

    if ($res->getErrorCode() == 0)
    {
      return $res;
    }
  }
  catch (Exception $e) {
    if (!empty($res->getData())) { /* Actual error response from Gigya */
      throw new GSApiException($res->getErrorMessage(), $res->getErrorCode(), $res->getResponseText(), $res->getString("callId", "N/A"));
    } else { /* Hard-coded error in PHP SDK, or another failure */
      throw new GSException($res->getErrorMessage(), $res->getErrorCode());
    }
  }
}
