User must be on whitelist error when using Facebook Ad Insights API

facebook-marketing-api

Solution

For testing purposes, I included every field described in the documentation, including `impressions_dummy`, which apparently causes that error.

¯\_(ツ)_/¯

Problem

Why does my query to the Ad Insights API result in the following response? ``` https://graph.facebook.com/v2.9/<ad_id>/insights?access_token=<access_token>&fields=... { "error": { "message": "(#3) User must be on whitelist", "type": "OAuthException", "code": 3, "fbtrace_id": "..........." } } ```
