Context.Items are only available when using a Map overload that takes Action<IMappingOperationOptions>! Consider using Context.TryGetItems instead

Question

I'm getting this error after upgrade from .NET 6 to .NET 8:

Context.Items are only available when using a Map overload that takes Action(IMappingOperationOptions)! Consider using Context.TryGetItems instead.

when mapping entity to model through automapper. here i have mention mapper profile from entity to model and also added entity and model for reference

Code:

_mapper.Map<List<UserRoleMapping>, List<UserRoleMappingModel>>(user.UserRoleMappings); getting error on this line

• UserRoleMapping is an entity
• UserRoleMappingModel is a model class
• user.UserRoleMappings is context result

Mapper profile

CreateMap<UserRoleMapping, UserRoleMappingModel>()
     .ForMember(m => m.UserRoleName, o => o.MapFrom(src => src.UserRole.Name))
     .ForMember(m => m.UserName, o => o.MapFrom(src => src.User.Name))
     .ForMember(m => m.Guid, o => o.MapFrom(src => src.UserRole.Guid.ToString()));

Enitity UserRoleMapping

public class UserRoleMapping : AbstractEntity
{
    public virtual int UserRoleId { get; set; }
    
    public virtual UserRole UserRole { get; set; }
    
    public virtual int UserId { get; set; }
    
    public virtual User User { get; set; }
    
    public virtual bool isReadOnly { get; set; }
    public virtual bool isReadWrite { get; set; }
    public virtual bool isAdmin { get; set; }
    public virtual bool IsEnterpriseAccess { get; set; }
}

UserRoleMappingModel

public class UserRoleMappingModel
{
  public int UserRoleId { get; set; }
    
    public string UserRoleName { get; set; }
    
    public int UserId { get; set; }
    
    public string UserName { get; set; }
    
    public string Guid { get; set; }
    
    public bool isReadOnly { get; set; }
    
    public bool isReadWrite { get; set; }
    
    public bool isAdmin { get; set; }
    
    public bool IsEnterpriseAccess { get; set; }
}

Previously it was working with .net6 i have updated all the package of automapper and efcore to latest release automapper 13.0.1 EfCore 8.0.6

Tough to say without seeing the properties in the Entity and the Model but you can try this:

var userRoleMappingsModel = _mapper.Map<List<UserRoleMappingModel>>(user.UserRoleMappings);
