facebook apprequests dialog error “An error occurred. Please try again later.”
===

I was searching all possible topics but now solution works for me.

There is my code, which works in all browsers except Chrome. There is just window with  “An error occurred. Please try again later.”.

It is identical code from FB documentation...

<div id="fb-root"></div>
    <script src="http://connect.facebook.net/en_US/all.js"></script>
   
    <script>
      FB.init({
        appId  : {$appId},
        frictionlessRequests: true
      });

      function sendRequestViaMultiFriendSelector() {
        FB.ui({ method: 'apprequests',
          message: '{_"FACEBOOK_INVITE_WINDOW_MESSAGE"}'
        }, requestCallback);
      }
      
      function requestCallback(response) {
        //callback code
      }
    </script>

<a onclick="sendRequestViaMultiFriendSelector(); return false;">

Thx for any help. Im out of any ideas.
