The code you're running is getting the value of a null object, so that object is thrown as well. When a query provider tries to convert that query into something that the database can do, it needs to parse Model.date.Value.Date as its value so that it can use that value in the query. Since there is no value, the code breaks.

The solution is of course not to inline such checks into the query itself. Outside of the query context, determine if this check should be added, and then add it only when needed:
