How to get rid of the error "No parameterless constructor defined for this object." when using automapper?

Question

ASP.NET

I add in services in this way: I tried it this way: I get an error
services.AddAutoMapper(typeof(Startup).Assembly);
services.AddAutoMapper();

"No parameterless constructor defined for this object."

Here is the config class:

public class DomainToDto: Profile
    {
        public DomainToDto()
        {
            CreateMap<A, ADto>();
            CreateMap<List<A>, List<ADto>>();
            CreateMap<B, BDto>();
            CreateMap<List<B>, List<BDto>>();
        }
    }

Class implementation:

public class B
    {
        [Required]
        public int Id { get; set; }
        [Required]
        public string Name { get; set; }
        [Required]
        public string Description { get; set; }

        public List<С> С { get; set; }

        public  List<D> D { get; set; }
        [Required]
        public int AId { get; set; }
        
        public A A { get; set; }

        public B(): base() { }

    }

public class A
    {
        [Required]
        public int Id { get; set; }
        [Required]
        public string Name { get; set; }
        [Required]
        public string Description { get; set; }

        public List<B> B { get; set; }

        public List<E> E { get; set; }

        public A(): base() { }
    }

 public class BDto
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Description { get; set; }
        public List<string> CId { get; set; }
        public List<string> DId { get; set; }
        public int AId { get; set; }

        public BDto(): base() { }
    }

public class ADto
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Description { get; set; }

        public ADto(): base() { }
    }
