Acumatica Web Service Endpoints - URL filter by datetime range

I just wondering if you can assist us with following issue regarding retrieving data via Web Service endpoints filtered by date time range. I created a General Inquiry that retrieves all open orders (SO) and expose it via Web Service Endpoint(6.00.001).

The issue I am facing now is that when I try to filter by datetime field (DueDate) between a date time range it does not work. I can only make it work if I filter by DueDate greater than or DueDate lower than using datetimeoffset but not between the datetime range.

Do you have any example of URL I can use to filter a Web Service Endpoint by datetime range?.

Thanks,
