I just created a fresh new Node.js Facebook app, hosted on Heroku. When I browse to my application however, it shows me the following error:

When I clone a copy of the application to my computer and check the logs, I see the following error:
Again, I did not touch any code yet. I'm new to Node.js, does anyone have suggestions on how to fix this?
The error code:
SyntaxError: Unexpected token S
2013-04-12T08:24:48.218425+00:00 app[web.1]: at Object.parse (native)
suggest you are having a problem parsing the response from Facebook. Then heroku closes the connection to the script. Try reviewing the IncomingMessage payload for a hint.
code=H13 desc="Connection closed without response"
I'm having a similar issue. Try logging out of facebook, you'll likely see the app working fine but when you login - Application Error
Is this what's going on with you too?
