March 2025 ECMWF seasonal forecast invalid request

Hi,
Trying to download sea surface temperature from ECMWF system #51 for the recently released March seasonal forecast. Have attempted to use both the API and online interface and receive this error:

invalid request
Error id: ff8a95f3-962b-4efa-8cae-60fb76053423

API request as provided by the web interface:

I had similar issues for the February forecast release, but they were resolved after a few days. Do ECMWF seasonal forecasts still get released on the 6th of each month or am I doing something else wrong?

Thanks,
Tyler
