Finance Report API - no data

I'm querying the Finance Report api to get a January report for my app, yet no data is present. It's now March 3rd, and executing the following query results in a 404.

url_financial = ( "https://api.appstoreconnect.apple.com/v1/financeReports" "?filter[regionCode]=ZZ" "&filter[reportDate]=2025-05" "&filter[reportType]=FINANCE_DETAIL" "&filter[vendorNumber]=redacted" )

If I change the report date to 2024-04, I get December, yet January is still unavailable. I understand that Apple's fiscal calendar does not follow the Gregorian calendar, however I'd expect that in March I could query the next period after December.

Is this normal?

2024-05 surely?
