Since 2021-04-28 01:00 UTC we are experiencing Facebook ads extractor failures on error "Please reduce the amount of data you're asking for, then retry your request"
It is caused by a bug in Facebook API that have been reported and currently being investigate by a Facebook backend team.
Link to the Facebook bug ticket: https://developers.facebook.com/support/bugs/503443564145524/
We continue to watch the Facebook bug ticket and will update here once we know more.
What can be done now
If you have access to the Facebook bug report you can raise importance/severity of it by leaving a comment there.
One possible workaround that might work is to retrieve data with smallest window possible that is adding .date_preset(yesterday) parameter to the query, e.g:
insights.action_attribution_windows(28d_click).action_breakdowns(action_type).level(adset).date_preset(yesterday).time_increment(1)
