Invalidcastexception: Unable to cast Object of type 'System.Int32' to type 'System.Int64

Question

I’m starting with Entity following this tutorial.

My method is giving error in function at the time of Savechanges();

My Controller:

[Route("api/[controller]")]
[ApiController]
public class EmpresaController : ControllerBase
{
    private readonly CrudContext _context;

    public EmpresaController(CrudContext context)
    {
        _context = context;

        if(_context.Empresas.Count() == 0)
        {
            _context.Empresas.Add(new Empresa { Nome = "Empresa", Cep = "14620-000"});
            _context.SaveChanges();
        }

    }

    //GET: api/empresa
    [HttpGet]
    public async Task<ActionResult<IEnumerable<Empresa>>> getEmpresas()
    {
        return await _context.Empresas.ToListAsync();
    }

My class Company:

{
    public class Empresa
    {
        public long Id { get; set; }
        public string Nome { get; set; }
        public string Cep { get; set; }
        public string Logradouro { get; set; }
        public string Complemento { get; set; }
        public int Numero { get; set; }
        public string Bairro { get; set; }
        public string Localidade { get; set; }
        public string UF { get; set; }
        public string Unidade { get; set; }
        public int IBGE { get; set; }
        public int GIA { get; set; }
    }

When I hit the api/company I get:

Invalidcastexception: Unable to cast Object of type 'System.Int32' to type 'System.Int64
