Question

I am using the PHP SDK to post to the logged in users timeline using the facebook::api method. I am pretty sure I had it working in the past but now it seems to fail and return the following error:

OAuthException: (#3502) Object at URL http://example.com/ has og:type
of ‘website’. The property ‘event’ requires an object of og:type
‘example:event’.

I have placed the URL into the Facebook debugger tool adn this returns fine. I have also used the Graph API explorer to test the POST request as well and this works. The only place it doesnt is from my PHP script.

I know I am not the only one who is experiencing this but it seems that everyone else is using the Javascript SDK so the solution is not relevant to me.

I have also tried setting scrape=true in my request but this makes no difference.

The code I am using is:

try{
    // Post the reply to the Facebook users wall
    $this->facebook_get_attendance['action_id'] = $this->facebook->api(
        "/me/example:reply?event=".urlencode("http://www.example.com/facebook-event/$this->area_rel/$this->facebook_event_reply_id")."&scrape=true&access_token={$this->facebook_user_details['access_token']}",
        "POST"
    );
    $this->facebook_get_attendance['action_id'] = $this->facebook_get_attendance['action_id']['id'];
}catch(FacebookApiException $e){
    error_log($e);
    $this->facebook_get_attendance['action_id'] = NULL;
}

Any ideas why this is happening?

The URL that is being passed is:

/me/example:reply?event=http%3A%2F%2Fwww.example.com%2Ffacebook-event%2Fbath%2F612&access_token=ACCESS_TOKEN

I have reported this as a bug with Facebook and it is currently in the ‘triaged’ stage. If and when I have any updates, I will post them here.
