I’m trying to retrieve all members in a Facebook group getting this error:
array(5) {
["message"]=>
string(66) "An unexpected error has occurred. Please retry your request later."
["type"]=>
string(14) "OAuthException"
["is_transient"]=>
bool(true)
["code"]=>
int(2)
["fbtrace_id"]=>
string(11) "AnfsXcdgM"
}
Here is my code:
$this->_facebook = new FacebookFacebook(array('app_id' => "$app_id",'app_secret' => "$secret",'default_graph_version' => 'v2.10'));
$this->_facebook->setDefaultAccessToken($_SESSION['facebook_access_token']);
$query = "/".$groupID."/members?fields=id,name,link,picture,first_name,last_name";
try{
$response = $this->_facebook->get($query);
while($pagesEdge)
{
$pageDecoded = json_decode($pagesEdge);
foreach($pageDecoded as $key => $member)
{
$id = $member->id;
}
}
}catch (FacebookExceptionsFacebookResponseException $e) { echo 'Graph returned an error: ' . $e->getMessage(); }
It works for groups with few hundreads of people (even once for a group with 10.000 members) but randomly I’m occurring to this.

I solved this by doing a cron that takes 100 data at the time and putting into a file text the value of the token for the next call.
I add this string on the query and when the fields inside $url are empty I quit my execution
This might be caused by a server side timeout. I get this error every now and then when I request a huge amount of data. Maybe you should try to limit your request by using the limit parameter (default should be 25).
