Facebook Actionscript API 'Facebook.Init()' call is suddenly returning null session object. Why?

Question

I have a game on Facebook that has been running successfully for almost a year now. It went offline this morning because my Flash Client which calls the facebook-actionscript-api:

Facebook.init(app_id, handleLogin)

...function, started getting a null response. And no error. The handleLogin() callback is called, function handleLogin(response:Object, fail:Object):void ...but both response and fail objects are null.

It started a little before 7pm, (19:00) Tuesday 8/May/2012 (PDT) - (California Time)

Anyone seen anything like this?

Answer 1

Yes we are also seeing the same issue as of midnight last night. We are still not sure the root cause of the problem. Trying to engage with facebook to find out.

Anyone else getting this?

update: Looks like a similar thing being reported in facebook bugs
