Facebook GraphAPI, Delete user invitation - facebook

Question

I'm using PHP and FacebookAPI, all is almost ok except for a strange error.
I tried to find solution on facebook developers site and google but with no luck.
This is the scenario:
Event 368441533230244 is created
User 100004484143351 is invited to the event 368441533230244
Now I want to remove the user from the event.
According to Facebook API docs, my APP own the permissions
rsvp_event
user_event
friend_event
And many others :)
Now calling the api:
$FB->api("368441533230244/invited/100004484143351", 'DELETE');
I obtain an Exception with the following details:
["result":protected] => array(1) {
["error"] => array(3) {
["message"] => string(8) "(#1002) "
["type"] => string(14) "OAuthException"
["code"] => int(1002)
}
I was unable to find something about Error Code 1002, and as you can see there is no error description.
Any idea? :)
Thanks in advance

Ok, this seems to be a side effect of the Events Timezone migration.
Events created using a web browser at facebook.com will behave like the migration is enabled. But your app probably has the Events Timezone migration disabled. This is causing a mismatch and the issue.
So do this: Keep the Events Timezone migration disabled in your app and create events using the Graph API instead of the web-ui/browser. This will ensure events are created and modified with the same migration setting.
You can check your app's migrations settings in the App Dashboard > Advanced > Migrations.
If you are using the Graph API Explorer to create events, make sure you select your App from the dropdown list "Application", at the top.
