[Question] API filter start_at and end_at did not work?

Welcome!

• I have searched open and closed issues and my problem was not mentioned before.
• I have verified I am using the latest version available. You can check the latest release here.

What did you do?

if i use api/v1/results i get all results. If I try api/v1/results?filter[start_at]>=2026-01-01 the data has no items. I try every variation like filter[start_at]>="2026-01-01" and filter[start_at]>="2026-01-01T00:00:00.000Z" and filter[start_at]="2026-01-01" - but nothing works. Only filter[start_at]<>"2026-01-01" gets again ALL results.
Is this my fault or a bug?
Thanks, Alex

The filtering in the API need some polishing. It does work when using for example filter[start_at]=>=2026-01-01 same for the end date with filter[end_at]=<=2025-01-05
