Facebook php schedule post - error unexpected exception - php

Question

I have a script for posting to managed pages which works unless i try and schedule the post. It fails on
Array ( [error] => Array ( [message] => An unexpected error has occurred. Please retry your request later. [type] => OAuthException [code] => 2 ) )
I came across this Facebook Graph API error when posting scheduled post on Business page stating it could be a issue with the "link" but not specifying which link. But i tried all of them but still getting the same errors.
Also on a side question....do page access tokens expire? There seems to be some confusion over these.
foreach($_POST['fb'] as $key=>$code){
$facebookpage= $key;
$facebookaccesstoken= $code;
$newfacebook = new Facebook(array(
'appId' => $appId,
'secret' => $appSecret
));
$time= time();
$newtime= $time +13600;
$attachment=array(
'access_token'=> $facebookaccesstoken,
'published' => false,
'scheduled_publish_time'=> $newtime,
'message'=> "new sasa posting me!",//user message
'name'=> 'Anyone sasa interested in this? Check out my advert!',//title
'link'=> 'http://testserverdavideec.mx.nf/wp-content/uploads/2014/05/user53734efe383247.67413395boats.jpg', // link to advert
'description'=> 'myadvert asa brings the milkshakes',//inner ad
'picture'=>'http://testserverdavideec.mx.nf/wp-content/uploads/2014/05/user53734efe383247.67413395boats.jpg',//picture url if empty= site logo
'actions'=>array(array(
'name'=>'dshjs',
'link'=>'http://testserverdavideec.mx.nf/wp-content/uploads/2014/05/user53734efe383247.67413395boats.jpg'
))
);
$post_url='/'.$facebookpage.'/feed';
try{
$result=$newfacebook->api($post_url,'POST',$attachment);
echo '<h1> result=</h1>'; var_dump($result);
} catch (FacebookApiException $e) {
print_r($e);
}
}

Answer 1

According to the official documentation it's NOT SUPPORTED to use published with actions field. So you can use either scheduled_publish_time or actions but both won't go.
I hope it helps.
