Facebook广告API无效参数问题ADGROUP_STATUS

我正在尝试使用Facebook广告API创建广告。到目前为止，我已经创建了广告集，广告创意和活动。但是，当我使用以下代码创建广告时，我接收的是Invalid Parameter exception。如果有的话，我在下面的代码中犯了什么错误?

Fatal error: Uncaught exception 'FacebookAds'Http'Exception'AuthorizationException' with message 'Invalid parameter'
  in /..../fbsdk/vendor/facebook/php-ads-sdk/src/FacebookAds/Http/Exception/RequestException.php:137

Your ads couldn't be created for the following reason: You must include the required field "adgroup_status"

我试过添加这个:

AdFields::STATUS => Ad::STATUS_PAUSED
or this
AdFields::ADGROUP_STATUS => AdGroup::STATUS_PAUSED,

，但它没有工作。

$ad->setData(array(
  AdFields::CREATIVE =>
    array('creative_id' => $creative->id),
  //AdFields::STATUS => Ad::STATUS_PAUSED, // try this but<-- this is ainvalid FB SDK 2.5.0
  AdFields::NAME => 'My First Ad',
  AdFields::ADSET_ID => $adset->id,
));
