Facebook Open Graph Beta: OAuthException

Trying to test the new Open Graph Beta to post a new action.

I'm following the official tutorial

It says to publish an action you would use this POST

    For example, sending a POST to:

https://graph.facebook.com/me/YOUR_NAMESPACE:cook
       ?recipe=OBJECT_URL&access_token=ACCESS开发者_开发百科_TOKEN

But in the JS call. There is no access token

FB.api('/me/YOUR_NAMESPACE:cook' + 
                    '?recipe=http://example.com/cookie.html','post',
                     function(response) {
                           ..........
                }

I get an error when i try to publish my own action. I have authenticated the publish_actions permission with the app

• "OAuthException" - "An unexpected error has occurred. Please retry your request later."

It might be possible you are not posting to the correct object. As in example 'cook' is action and 'recipe' is object..So the 'OBJECT_URL' must be of type 'recipe' as far as tutorial is concerned.

Since timeline is not launched therefore when you create your own object facebook provides you a sample url of that type which can be used to test the posting of your app.
