Automapper v3.3.1.0 Missing type map configuration or unsupported mapping

Question

I get the error Missing type map configuration or unsupported mapping.

Version of AutoMapper: v3.3.1.0

My code is:

Global.asax

protected void Application_Start()
{
   AutoMapperWebConfig.RegisterMappings();
   AutoMapperServiceConfig.RegisterMappings();
}

AutoMapperWebConfig:

public class AutoMapperWebConfig
{
    public static void RegisterMappings()
    {
        Mapper.Initialize(cfg =>
        {
            cfg.AddProfile<DtoToViewModelMappingProfile>();
        });
    }
}

AutoMapperServiceConfig:

public class AutoMapperServiceConfig
{
    public static void RegisterMappings()
    {
        Mapper.Initialize(cfg =>
        {
            cfg.AddProfile<DomainToDtoMappingProfile>();
        });
    }
}

DtoToViewModelMappingProfile:

public class DtoToViewModelMappingProfile : Profile
{
    public override string ProfileName
    {
        get { return "DtoToViewModelMappings"; }
    }

    protected override void Configure()
    {
        Mapper.CreateMap<PartnerSearchResultDTO, PartnerSearchResultVM>();
    }
}

DomainToDtoMappingProfile:

public class DomainToDtoMappingProfile : Profile
{
    public override string ProfileName
    {
        get { return "DomainToDtoMappings"; }
    }

    protected override void Configure()
    {
        Mapper.CreateMap<Partner, PartnerSearchResultDTO>();
    }
}

When I try to invoke the mapping:

   public virtual PartialViewResult Search(PartnerSearchVM partnerSearch)
    {
        var partnerServices = new PartnerService();

        var partnersDTO = partnerServices.Search(partnerSearch.Service_Id, partnerSearch.Brand_Id, partnerSearch.LocationLatitude, partnerSearch.LocationLongitude, 20);

        var partnersVM = Mapper.Map<IList<PartnerSearchResultDTO>, IList<PartnerSearchResultVM>>(partnersDTO);

        return PartialView(MVC.Partner.Views.List, partnersVM);
    }

I get the error:

Missing type map configuration or unsupported mapping.

Mapping types:
  PartnerSearchResultDTO -> PartnerSearchResultVM
  PRJ.Services.DtoModels.PartnerSearchResultDTO ->       PRJ.ViewModels.PartnerSearchResultVM

Destination path:
IList`1[0]

Source value:
PRJ.Services.DtoModels.PartnerSearchResultDTO

If I debug the Global.asax I get the error in the code:

cfg.AddProfile<>

You need to have one initialize method.

Mapper.Initialize(cfg =>
{
    cfg.AddProfile<DtoToViewModelMappingProfile>();
    cfg.AddProfile<DomainToDtoMappingProfile>();
});

The Initialize method clears out any previous configuration if you call it more than once.
