Automapper

Olá, devs, tudo bem? Eu estou com uma dificuldade estranha com o programa que esta sendo criado. De inicio, achei que o problema era algo com meu código, porém, após realizar a instalação da aula 1, continuei com o mesmo problema.

Este é o erro:

System.InvalidOperationException: Unable to resolve service for type 'AutoMapper.IMapper' while attempting to activate 'FilmesAPI.Controllers.EnderecoController'.

Este é o código:

public class EnderecoProfile : Profile
    {    
        public EnderecoProfile()
        {
            CreateMap<CreateEnderecoDto, Endereco>();
            CreateMap<Endereco, ReadEnderecoDto>();
            CreateMap<UpdateEnderecoDto, Endereco>();
        }
    }

[HttpPost]
        public IActionResult AdicionaEndereco([FromBody] CreateEnderecoDto enderecoDto)
        {
            Endereco endereco = _mapper.Map<Endereco>(enderecoDto);
            _context.Enderecos.Add(endereco);
            _context.SaveChanges();
            return CreatedAtAction(nameof(RecuperaEnderecosPorId), new { Id = endereco.Id }, endereco);
        }
