OrderBy containing "null" throws error:

[tbeltram]

This code worked perfectly in Version 1.4.6

query.OrderBy("x => x.DateDelivered == null ? 1 : 2")

After updating to 1.6.3 we get this error:
'No property or field 'null' exists in type '(Type)''

The problem seems to be, the parser cannot understand, that null is not a field of the entity but a constant expression.

Is this a bug?

If DateDelivered is not a property or field, the OrderBy will fail unless the new flag RestrictOrderByToPropertyOrField in the ParsingConfig is manually set to false:

var config = new ParsingConfig()
{
    RestrictOrderByToPropertyOrField = false
};
var orderedQuery = query.OrderBy(config, "x => x.DateDelivered == null ? 1 : 2");

P.S.: If using entity framework, it seems like even having a Column attribute on an entity field will make the OrderBy fail if the config is not set:

[Column("DeliveredDate")]
public DateTime? DateDelivered { get; set; }

The answer from @bzaugt is correct.
See also https://github.com/zzzprojects/System.Linq.Dynamic.Core?tab=readme-ov-file#change-2

I did now know that this also fails for using entity framework with column-attribute.
@bzaugt Can you please create a new issue with full example?

@StefH sure, see #928
