How can I access the read permissions for built in verticals?

According to http://developers.facebook.com/docs/beta/authentication/read/, I can prompt a user for the permission "user_actions.music" and have access to their actions on the open graph. I've enabled the Enhanced Auth Dialog setting on my test app but am receiving an invalid parameter error when I try to prompt a user for that permission. I've also tried prompting the user for "user_actions" and experience the same error. Is this permission not active yet, even though I'm a develope开发者_StackOverflow社区r or am I asking for this permission incorrectly?

The Open Graph isn't live to users yet. Only developers of your app should be able to grant these permissions.
