[Binu Mathew]

Hi All

Here is the code i use get languages set to an individual campaign 

$language_query='SELECT language_constant.id FROM campaign_criterion';

         if ($id !== null) {

            $language_query .= " WHERE campaign.id= $id ";

        }

        $response =$googleAdsServiceClient->searchStream('<account_id> ',$language_query);

      

        foreach ($response->iterateAllElements() as $googleAdsRow) {

            $campaignCriterion = $googleAdsRow->getCampaignCriterion();

            $newCompete = new \StdClass();          

            $newCompete->langauge_code = $campaignCriterion->getLanguage()->getCode();

             array_push($googleAdsRow, $newCompete);

Hi Binu,

Thank you for posting your concern.

It appears that the code could not properly get the methods under the CampaignCriterionService and this is the possible reason why the error occurred. With this, I would suggest reaching out to the author of the client library via this link to get assistance to this concern and to address the issue. The author of the client library is more equipped to provide support to code related issues / concerns.

Regards,
