{
LoadAdError loadAdError = args.LoadAdError;
// Gets the domain from which the error came.
string domain = loadAdError.GetDomain();
// Gets the error code. See
// https://developers.google.com/ad-manager/mobile-ads-sdk/android/reference/com/google/android/gms/ads/AdRequest
// and https://developers.google.com/ad-manager/mobile-ads-sdk/ios/api/reference/Enums/GADErrorCode
// for a list of possible codes.
int code = loadAdError.GetCode();
// Gets an error message.
// For example "Account not approved yet". See
// https://support.google.com/admob/answer/9905175 for explanations of
// common errors.
string message = loadAdError.GetMessage();
// Gets the cause of the error, if available.
AdError underlyingError = loadAdError.GetCause();
// All of this information is available via the error's toString() method.
Debug.Log("Load error string: " + loadAdError.ToString());
// Get response information, which may include results of mediation requests.
ResponseInfo responseInfo = loadAdError.GetResponseInfo();
Debug.Log("Response info: " + responseInfo.ToString());
}
