AutoMapper & .NET Core: Missing type map configuration or unsupported mapping

Question

Today I have ran into an issue which I haven't been able to solve for the past hours. I have created a GitHub Gist here which shows my code. The error that AutoMapper has been returning is the following:

Missing type map configuration or unsupported mapping.
Mapping types:
Object -> Order
System.Object -> Rig.Commercial.Reservation.DataStorage.Entities.Order

Can someone help me out?

Answer 1

It looks like the way you constructed your Profile class is wrong. That is BookingsMappers class in your code.

According to the documentation here. The fix might be replacing your BookingsMappers class to like this:

public class BookingsMappers : Profile
{
    public BookingsMappers()
    {
        CreateMap<CreateBooking, Order>()
            .BeforeMap((createBooking, order) => order.Created = DateTime.Now)
            .BeforeMap((createBooking, order) => order.Modified = DateTime.Now)
            .BeforeMap((createBooking, order) => order.InternalId = Guid.NewGuid());
    }
}
