Invalid parameter while creating adset - php

Question

While creating an Adset in facebook-ads-sdk i get invalid parameter. I tried my best to track and resolve the problem but couldn't succeed. Please help. Following is the code snippet:
function adddSet($audienceid,$parentId,$accountId2,$campaignid,$productSetId){
try {
$adset = new AdSet(null, $accountId2);
$adset->setData(array(
AdSetFields::NAME => 'test',
AdSetFields::DAILY_BUDGET =>40000,
AdSetFields::BID_AMOUNT =>4000,
AdSetFields::BILLING_EVENT => BillingEvents::IMPRESSIONS,
AdSetFields::OPTIMIZATION_GOAL => OptimizationGoals::APP_INSTALLS,
AdSetFields::CAMPAIGN_ID => $campaignid,
AdSetFields::START_TIME => '2016-04-11T09:22:03+00:00',
AdSetFields::END_TIME =>'2016-04-20T09:22:03+00:00',
AdSetFields::TARGETING => (new TargetingSpecs())->setData(array(
TargetingSpecsFields::GEO_LOCATIONS => array(
'countries' => array('JP'),
'regions' => array(array('key' => '3886')),
'cities' => array(
array(
'key' => '2420605',
'radius' => 10,
'distance_unit' => 'mile',
),
),
),
TargetingSpecsFields::GENDERS => array(1),
TargetingSpecsFields::AGE_MIN => 20,
TargetingSpecsFields::AGE_MAX => 24,
TargetingSpecsFields::PAGE_TYPES => array(
PageTypes::MOBILE_FEED,
PageTypes::MOBILE_EXTERNAL,
),
)),
));
$adset->create(array(AdSet::STATUS_PARAM_NAME=>AdSet::STATUS_PAUSED));
}
catch(\FacebookAds\Http\Exception\RequestException $e){
echo $e->getMessage();
}
}
and get the following response:
Invalid parameter
