Cannot update AdGroupAd using GoogleAds API

[integrations bidalgo]

Hi,

I’m trying to update texts for an AdgroupAd using the following code (using GoogleAds API):

{
    $appAdInfo = new AppAdInfo();
    $headlinesAssets = $this->stringArrayToAdAssetTextArray(['Head', 'Head2']);
    $appAdInfo->setHeadlines($headlinesAssets);
    $descriptionsAssets = $this->stringArrayToAdAssetTextArray(['Decs1']);
    $appAdInfo->setDescriptions($descriptionsAssets);

    $appAd = new Ad(['app_ad' => $appAdInfo]);
    // Creates an ad group ad to hold the above ad.
    $adGroupResourceName = new StringValue(['value' => ResourceNames::forAdGroup($this->account_google_id,XXXXXXX)]);
    $adGroupAd = new AdGroupAd([
        'ad_group' => $adGroupResourceName,
        'ad' => $appAd
    ]);

    $adGroupAdOperation = new AdGroupAdOperation();
    $adGroupAdOperation->setUpdate($adGroupAd);
    $adGroupAdOperation->setUpdateMask(FieldMasks::allSetFieldsOf($adGroupAd));
    $operations[] = $adGroupAdOperation;

    return $this->adGroupAdServiceClient->mutateAdGroupAds($this->account_google_id, $operations);
}

Getting error: "Request contains an invalid argument.”

Hi, 

It is not possible to mutate Ad Group Ads using AdGroupAdService. You will need to use AdService for updating existing ads that were created using AdGroupAdService. Could you please give this a try with AdService and let me know if you encounter any issues?
