Mapper fails when type contains DateOnly property

[salmanbabri]

An earlier issue mentioned that DateOnly is not natively supported in this library. So I included the following when configuring my mapper:-

.UseMapping(cfg => { cfg.Options.Primitives.Add(typeof(DateOnly)); })

Then I map dto to model using code:-

var stock = await context.MapAsync<Stock>(vm);

I still get the error:-

ArgumentException: Static property requires null instance, non-static property requires non-null instance. (Parameter 'expression') System.Linq.Expressions.Expression.Property(Expression expression, PropertyInfo property)

Does anyone have a solution to this problem?

Hi @salmanbabri, sorry for the late response, I've been busy starting a new job and dealing with personal problema!
Looking at the error you provided, it seems that there is a method call without a proper target, but I can't figure out why.
I guess it only happens with dateonly but works with other types....
Is the dateonly nullable? Would You send a copy of the entire model to take a look at it?
