I using automapper in my project as in documentation:

1. Configurated it with class:

public class AppMappingProfile : Profile
{
    public AppMappingProfile()
    {
        CreateMap<UserEntity, UserModel>().ReverseMap();
    }
}

Enity code:

public record UserEntity(
    int Id, 
    string Name, 
    string Email, 
    string PasswordHash, 
    Roles Roles) : IEntity;

Model code:

public record UserModel(
    string Name, 
    string Email, 
    string PasswordHash,
    Roles Roles = Roles.Default);

2. Added it to services:
   services.AddAutoMapper(typeof(AppMappingProfile));

3. I need to use it in method:

public async Task Add(UserModel user)
    {
        UserEntity userEntity = _mapper.Map<UserModel, UserEntity>(user);
        
        await _dbContext.Users
            .AddAsync(userEntity);
        
        await _dbContext.SaveChangesAsync();
    }

I debuged it, request data is correct but _mapper.Map() return null

It worked good before, but after some changes (I think i did not changed any logic in this blocks) it broke

I think it might be cause of:

1. I started to use records but not classes
2. UserModel does not have a property Id
