Проблемы в создании рекламных объявлений в Facebook

Ниже приведен мой код для создания рекламы, и я получаю фатальную ошибку на шаге 7:

public function add_ads($account_id,$campaign_id){
/**
* Step 3 Search Targeting
*/
$results = TargetingSearch::search(
$type = TargetingSearchTypes::INTEREST,
$class = null,
$query = 'facebook');

// we'll take the top result for now
$target = (count($results)) ? $results->current() : null;

echo "Using target: ".$target->name."\n";
print_r($target);

$targeting = new TargetingSpecs();
$targeting->{TargetingSpecsFields::GEO_LOCATIONS}
= array('countries' => array('GB'));
$targeting->{TargetingSpecsFields::INTERESTS} = array(
array(
'id' => $target->id,
'name' => $target->name,
),
);
print_r($targeting->getData());
/**
* Step 4 Create the AdSet
*/
$adset = new AdSet(null, "act_".$account_id);
var_dump($account_id);
//var_dump(expression)
$adset->setData(array(
AdSetFields::ACCOUNT_ID => "act_".$account_id,
AdSetFields::NAME => 'My First AdSet',
AdFields::BID_TYPE => 'CPC',
AdSetFields::BID_INFO => array('CLICKS' => 500),
AdSetFields::CAMPAIGN_ID => $campaign_id,
AdSetFields::TARGETING => $targeting,
AdSetFields::OPTIMIZATION_GOAL => AdSetOptimizationGoalValues::REACH,
AdSetFields::BILLING_EVENT => AdSetBillingEventValues::IMPRESSIONS,
AdSetFields::BID_AMOUNT => 2,
AdSetFields::DAILY_BUDGET => 4000,
AdSetFields::START_TIME =>(new \DateTime("+1 week"))->format(\DateTime::ISO8601),
AdSetFields::END_TIME =>(new \DateTime("+2 week"))->format(\DateTime::ISO8601),
));
print_r($adset->getData());
$adset->validate()->create(array(
AdSet::STATUS_PARAM_NAME => AdSet::STATUS_PAUSED,
));

echo 'AdSet  ID: '. $adset->id . "\n";

/**
* Step 5 Create an AdImage
*/

$image = new AdImage(null, "act_".$account_id);
$image->{AdImageFields::FILENAME}
= __DIR__.'/avatar3.jpg';
print_r($image);
$image->create();
echo 'Image Hash: '.$image->hash . "\n";

/**
* Step 6 Create an AdCreative
*/$creative = new AdCreative(null, "act_".$account_id);
$creative->setData(array(
AdCreativeFields::NAME => 'Sample Creative',
AdCreativeFields::TITLE => 'Welcome to the Jungle',
AdCreativeFields::BODY => 'We\'ve got fun \'n\' games',
AdCreativeFields::IMAGE_HASH => $image->hash,
AdCreativeFields::OBJECT_URL => 'http://www.example.com/',
));

$creative->create();
echo 'Creative ID: '.$creative->id . "\n";

/**
* Step 7 Create an Ad
*/
$ad = new Ad(null, "act_".$account_id);

$ad->setData(array(
AdFields::CREATIVE =>
array('creative_id' => $creative->id),
AdFields::NAME => 'My First Ad',
AdFields::ADSET_ID => $adset->id,
));
print_r($ad);
$ad->create(array(Ad::STATUS_PARAM_NAME => Ad::STATUS_PAUSED));
echo 'Ad ID:' . $ad->id . "\n";
return $ad;
}

Вот ошибка, которую я получаю:
