Problems with API on billboard queries

Several of the billboard queries in the API allow specifying a date (e.g. { "date": "2024-02-28", "rank": 1 } which is the example given in the documentation for the endpoint /music/get_billboard_rank_date). However, sending a query for an adjacent date, like 2024-02-27 returns empty arrays for this example. I tried a handful of dates and they all return empty lists except for the example date 2024-02-28. This affects the other billboard endpoint APIs as well.

For context, I am using the Docker container, but running from source.
