Failed to format date. Not given in any of the valid formats.

The FromDate and ToDate parameter options don't work and returns an Api Exception.

await orderConnector.FindAsync(new  OrderSearch()
{
FromDate = DateTime.Now,
ToDate = DateTime.Now
});

Reply from Fortnox Support:
Currently used url and parameters: 3/orders?fromdate=2024-01-01%2011%3A23%3A38&todate=2024-03-01%2011%3A23%3A38&page=1

Using 3/orders/?fromdate=2024-01-01&todate=2024-03-01&page=1 the error message will disappear.

If you use dates without a timestamp (as shown in the second url) there should be no errors.

So, the following example should be working.
FromDate = new DateTime(2024, 1, 1)

Do you need to use timestamps in the search?
