HTTP POST to Facebook Graph API (for wall post) throwing OAuthException
I'm POSTing to a user's news feed with the following JSON:

    { message: 'This is a test.',
      access_token: 'A_VALID_TOKEN',
      application: { name: 'APP_NAME', id: 'APP_ID' },
      actions: [ { name: 'Test Link', link: 'http://google.com' } ] }

This throws an `OAuthException` like so:

    {"error":{"message":"(#200) This API call requires a valid app_id.",
    "type":"OAuthException"}}

The `app_id` is definitely valid, so I'm not sure I understand the issue here.
