getStatus Request without date returns Bad request

I’m using the getStatus API call to get the latest date where i uploaded data to pvoutput and continue the further upload from there.
Right now however it seems this behavior has changed to require a date parameter to work.
And even a date parameter where data was submitted.
Without any date i get a 400 Bad Request result.

Is this intentionally, or a bug?

The Endpoint used: works (as i have uploaded data there) does not work, but previously returned just the latest upload date as part of the result.

Thanks for any hints.

Previously the API would keep track of last upload statuses for several months, now only the last 1-2 days is kept. A Get Status without a date parameter would only work for systems that are still alive.
