Analytics API aggregation by queue and media type returning empty results

Hitting /api/v2/analytics/conversations/queries with an aggregation on queue and media type, but the response is empty. Checked the date range and scopes, everything looks fine. Here’s the payload I’m sending:

{"aggregation": {"groupBys": [{"type": "queue"}, {"type": "mediaType"}]}, "dateFrom": "2023-10-01T00:00:00.000Z", "dateTo": "2023-10-02T00:00:00.000Z"}

Why isn’t it returning any data?
