Facebook Insights API - getting error code 1 with subcode 99

Question

We are retrieving Insights data via the Facebook Marketing API. We are using the Python "facebookads" module for this. I was downloading historic data in the past for all of our accounts which was working perfectly fine. Since 2 weeks or so I am getting this error:

2018-06-01 16:01:57 - (DEBUG) - urllib3.connectionpool - https://graph.facebook.com:443 "GET /v2.11/act_nnnn/insights?access_token=&appsecret_proof=&time_range=%7B%22since%22%3A%222018-05-08%22%2C%22until%22%3A%222018-05-08%22%7D&level=ad&breakdowns=%5B%22impression_device%22%5D&filtering=%5B%7B%22field%22%3A%22spend%22%2C%22operator%22%3A%22GREATER_THAN%22%2C%22value%22%3A%220%22%7D%5D&limit=5000&fields=account_id%2Ccampaign_id%2Ccampaign_name%2Cadset_id%2Cadset_name%2Cad_id%2Cad_name%2Cimpressions%2Cclicks%2Creach%2Cspend%2Caccount_currency%2Cactions%2Caction_values%2Ctotal_actions%2Ctotal_action_value HTTP/1.1" 500 77

2018-06-01 16:01:57 - (DEBUG) - FacebookAdsDownloader - An exception occurred:

Status: 500

Response: { "error": { "code": 1, "message": "An unknown error occurred", "error_subcode": 99 } }

Anyone has an idea, why I get this error? This very same request was working already. I have retried the same request over and over.

Shireesh Asthana from Facebook Developer team mentions here that too much data is requested and asynchronous requests have to be used. Example can be found here: retrieve async ads insights results from FB ads API with pagination
