We are participating in the Facebook Credits beta. After approval of our live app, we followed the steps from the API page to set up the demo application: http://developers.facebook.com/docs/creditsapi
However, whenever we submit with the "Pay with Facebook" button, we are getting back error 1383008 ("The application you are using is not responding").
We've checked the server logs and confirmed that all necessary params are passing to http://apps.facebook.com/ajax/flows/?__a=1 as expected. We've also confirmed that the callback URL (callback.php from the demo app files) is never being hit.
Just to be certain this isn't a compatibility issue with the new JavaScript SDK, we set up the demo using the old JS SDK and got the same error.
Has anyone else experienced this issue with running the demo application (using either version of the SDK)? If we can't get the demo to run, we can't implement this feature in our live app.
Here is the request sent to the server (app ID removed):
