Calling any endpoint for user insights metrics doesn't work anymore for us.

Request example: {instagram_business_id}/insights?metric=engaged_audience_demographics&period=lifetime&metric_type=total_value&timeframe=this_month&breakdown=age

Response example: { "error": { "message": "An unknown error has occurred.", "type": "OAuthException", "code": 1, "fbtrace_id": "AXftv7U8u2ZL7OdCEAVlYIR" } }

The same endpoints were working 2 days ago.. any suggestion? Thank you
