I have a problem to map the properties using Automapper.
Mapping is for a destination type MyClass and source type IMyInterface. Here are a models.
Source type where ElectricPotential is struct of UnitsNet and concrete type on return for IProperty is Property which is internal class in another package:

public interface IMyInterface
{
 IProperty<ElectricPotential?> NominalVoltage { get; set; }
}

Destination type where Units is my class to which I want to map:

public class MyClass : IMapFrom<IMyInterface>
{
 IProperty<Units> NominalVoltage { get; set; }

 public void MapFrom(Profile profile)
{
    profile.CreateMap<IMyInterface, s>()
        .ForMember(dest => dest.NominalVoltage,
            opt => opt.MapFrom(src => src.NominalVoltage));

    profile.CreateMap<ElectricPotential, Units>()
        .ForMember(dest => dest.Unit, opt
            => opt.MapFrom(src => src.Unit.ToString()))
        .ForMember(dest => dest.Value, opt
            => opt.MapFrom(src => src.Value));
}
}

Versions:
.NET 8
AutoMapper 12.0.0
MSA.BuildingBlocks.Mapping 0.1.1

I tried to map using this code:

 public void MapFrom(Profile profile)
{
    profile.CreateMap<IMyInterface, s>()
        .ForMember(dest => dest.NominalVoltage,
            opt => opt.MapFrom(src => src.NominalVoltage));

    profile.CreateMap<ElectricPotential, Units>()
        .ForMember(dest => dest.Unit, opt
            => opt.MapFrom(src => src.Unit.ToString()))
        .ForMember(dest => dest.Value, opt
            => opt.MapFrom(src => src.Value));
}

But I receive

AutoMapper.AutoMapperMappingException: Error mapping types.

Mapping types:
IMyInterface-> MyClass 

Type Map configuration:
IMyInterface-> MyClass 


Destination Member:
NominalVoltage

 ---> AutoMapper.AutoMapperMappingException: Missing type map configuration or unsupported mapping.

Mapping types:
Property`1 -> IProperty`1
Property`1[[System.Nullable`1[[UnitsNet.ElectricPotential, UnitsNet, Version=5.0.0.0, Culture=neutral, PublicKeyToken=f8601875a1f041da]], System.Private.CoreLib, Version=8.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]] -> IProperty`1[[S.Units, SapIntegration.Api, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]]

I expect to map this struct. Because there are another type of structs from UnitsNet to map.
