Facebook App Test Users - Doesn't work with FB.UI ()

Question

I am trying to use a simple Share dialog that is invoked through Javascript on a website page. I can download fine SDK:

         window.fbAsyncInit = function() {
       FB.init({
         appId      : '{My-App-ID}',
         xfbml      : true,
         version    : 'v2.0'
       });
     };

     (function(d, s, id){
        var js, fjs = d.getElementsByTagName(s)[0];
        if (d.getElementById(id)) {return;}
        js = d.createElement(s); js.id = id;
        js.src = "//connect.facebook.net/en_US/sdk.js";
        fjs.parentNode.insertBefore(js, fjs);
      }(document, 'script', 'facebook-jssdk'));

And my javascript function is taken directly from FB Docs:

    FB.ui(
     {
      method: 'share',
      href: 'https://developers.facebook.com/docs/'
    }, function(response){});

The problem is testing. To do this, I created a test application in my main application. My personal Facebook account is the administrator of this application. When I log in to my personal account, I can call the exchange dialog and it works fine.

However, when I create a "Test User" from the "Roles → Test Users" section of the application panel and register as him, I get the following error when trying to call the sharing dialog:
