It sounds like your filtering logic is correctly recognized by the Meta API, but it’s not actually applying the filter to remove ads with no data. A few things you might want to check:

Verify the Filtering Logic – Make sure you're using the correct operator and value. For example, when filtering by impressions, try setting impressions > 0 to exclude ads with no data.

Check the API Response Structure – Sometimes, insights might return an empty array instead of null or 0. If that’s the case, you may need to filter the results in your code after retrieving the data.

Ensure Data Availability – If you’re requesting data for a specific timeframe, double-check that insights are actually available for that period. Some ads might not have data yet, depending on when they were run.

Use a Post-Request Filter – If the API isn’t filtering properly, consider fetching all results first and then filtering out empty or zero-value entries in your code.

If the issue persists, you might want to check the API documentation or test different filtering approaches to see if one works better. Let me know if you need more help!
