Date fields cannot be saved to DB while DateTime works

[v4ssili]

Hi there, I'm having troube when trying to save a Document with a basic date field:
last_update: datetime.date = mongoz.Date() like described https://mongoz.tarsild.io/fields/#date

error message: bson.errors.InvalidDocument: cannot encode object: datetime.date(2024, 7, 10), of type: <class 'datetime.date'>

When I change the type to last_update: datetime.datetime = mongoz.DateTime() everything works fine.
Is this an issue with mongoz or with how MongoDB/BSON handles dates, can we only use DateTime?

Thanks in advance
