We tried to add new ImageAds using by the GoogleAds API Ver 2.2.0.
We used the below code :
```
$imageAdInfo = new ImageAdInfo([
'data' => new BytesValue(['value' => file_get_contents($image)]),
]);
$ad = new Ad([
'image_ad' => $imageAdInfo,
'final_urls' => [
new StringValue(['value' => $urlFinal]),
],
]);
$adGroupAd = new AdGroupAd([
'ad_group' => $adGroupResourceName,
'status' => AdGroupAdStatus::ENABLED,
'ad' => $ad,
]);
$operationAdd = new AdGroupAdOperation();
$operationAdd->setCreate($adGroupAd);
$operations[] = $operationAdd;
…
$adGroupAdService->mutateAdGroupAds(GOOGLE_ADS_CUSTOMER_ID, $operations);
```
However, we got the following error message from API:
```
google-ads.WARNING: Request made: Host: "
googleads.googleapis.com", Method: "/google.ads.googleads.v2.services.AdGroupAdService/MutateAdGroupAds", ClientCustomerId: XXXXXXX, RequestId: "XXXXXXXX", IsFault: 1, FaultMessage: "["The required field was not present.","A required field was not specified or is an empty string."]"
```
So, we want to know the required fields to add the new ImageAd.
However, we couldn't find the information about this.
Could you please tell us the required fields in the above case?
Best Regards.
