How to get instgram demographic insights with multiple breakdown values at a time

Hi Team,
I am getting result if i'm using only one breakdown at a time like age,city or country. {media_id}/insights?metric=follower_demographics&period=lifetime&metric_type=total_value&breakdown=age
However getting error when using more than one breakdown at a time.Please find the example below :-
For Ex:- {media_id}/insights?metric=follower_demographics&period=lifetime&metric_type=total_value&breakdown=age.city,country
o/p :- { "error": { "message": "An unknown error has occurred.", "type": "OAuthException", "code": 1, "fbtrace_id": "A_tJhk6-ZU-jxLXPRLWZ6nr" } }
How can i use more than one breakdown at a time to get data fom api.Could you please share the correct way to fetch multiple breakdowns.
