Missing type map configuration or unsupported mapping error in Automapper

Question

I am using an Automapper to map one model to second model which has some rows with the same name as the first model. I am getting this inner exception

Missing type map configuration or unsupported mapping.
Mapping types: Bed -> Bed Model1.Bed -> Model2.Bed

This is the condensed version of the code.

Model 1

public class Model1
{
    public Guid Id { get; set; }
    public string Name { get; set; }
    public IEnumerable<Bed> Beds { get; set; }
    public IEnumerable<Bed> Beds1 { get; set; }
    public string Status {get; set;}
    public string Notes {get; set;} 
}
public class Model2
{
    public Guid Id { get; set; }
    public string Name { get; set; }
    public IEnumerable<Bed> Beds { get; set; }
    public IEnumerable<Bed> Beds1 { get; set; }
}


public class Bed
{
    public Guid Id { get; set; }
    public Guid TypeId { get; set; }
    public string Type { get; set; }        
    public string Notes { get; set; }
    public DateTime? CreatedOn { get; set; }
    public DateTime? LastUpdatedOn { get; set; }
}

Mapping :

 MapperConfiguration config = null;
 config = new MapperConfiguration(cfg => { cfg.CreateMap<Model1, Model2>(); });           
 IMapper mapper = config.CreateMapper();
 var dest = mapper.Map<Model1, Model2>(update);

update is an instance of Model1. Am I missing something? Should I do something with regards to the Bed class mapping even though both reference the same method? Also is there a way to copy data from one model to another in this scenario other than manually doing it or using Automapper?

EDIT 1: I am sure the error is from that mapping. I removed it and all the other fields were fine and there was no exception. But I am not sure how I should do the Bed -> Bed binding.

EDIT 2:This link seems to have the same issue and they say it's a possible bug and This one seems to have the answer although I am not sure how I can adapt it to my situation.

Answer 1

It seems like auto mapper is having trouble determining how to map Bed. I would try the following:

config = new MapperConfiguration(cfg => { 

     cfg.CreateMap<Model1, Model2>(); 
     cfg.CreateMap<Bed, Bed>();

});

Although it seems odd that would be necessary...
