Facebook Graph API Insights returns empty array

Question

I cannot figure out how to get particular Facebook Insight metrics, and don't know if I am missing something, or doing something wrong, or there is a bug ... ?

I'm using JS SDK v2.0. After logging in, I have 4 granted permissions (FB.api("/me/permissions" ...): public_profile, email, read_insights, manage_pages. Then, for the sake of an example, let's say I want to get page impressions of Lufthansa page. I tried:

FB.api("/lufthansa/insights/page_impressions",...)

FB.api("/{lufthansa-page-id}/insights/page_impressions",...)

FB.api("/lufthansa/insights/page_impressions?period=day",...)

FB.api("/lufthansa/insights/page_impressions?period=day&since=1396310400&until=1399075200",...)

None of these work. Or to be precise, all of those return empty array ({data:Array[0],paging:Object}). Can anybody help me out with tip what am I doing wrong? I also couldn't find any example online; there are many simple FB API examples, but none with working FB Insights API ...

Thank you, Ales

So I found that the problem is actually a documented bug. https://developers.facebook.com/bugs/665575443480429/
