Uncaught exception 'FacebookRestClientException .. while trying to set users staus via a facebook application

Question

Hello,

I am trying to set users status using my facebook application. However my

$uid = $facebook->require_login($required_permissions = 'email,status_update,offline_access');

gives me an infinite redirect which I am still trying to debug.

However, if I hard code the value of uid and then use

$facebook->api_client->users_setStatus("hello",$uid) 

then:

1. I am able to update the users status message for the first time.
2. However , If I repeat it again after the status is updated; I get :

Fatal error: Uncaught exception 'FacebookRestClientException' with message 'An unknown error occurred' in s/PATH/facebookapi_php5_restlib.php(1813): FacebookRestClient->call_method('facebook.users....', Array) #1 /PATH/file.php(9): FacebookRestClient->users_setStatus('hello', '1000247983459873') #2 {main} thrown in /PATH/facebookapi_php5_restlib.php on line 3065

Following are the lines corresp to line 3065:

if (is_array($result) && isset($result['error_code'])) { 3065 throw new FacebookRestClientException($result['error_msg'], 3066 $result['error_code']); 3067 } 

Can someone please help me what could be the problem here.
