Hello, I am new in XAMARIN, i have a simple APP in VS2022.
Here is part of the code:
public interface IRepository
   {
       [Get("/package/")]
       Task<Resultado> GetAllData();
   }


public class PaqueteServicio
   {
       public const string API_BASE_URL = "http://www.mi.traelopaq.net/listarpaqjson.php?text1=2264&text2=pOADSIQMASD.O398AJas&KEYAPI=ODUTRAS.9di23821@ldpli2skjs43&KEYPASo=OASmsjdu38IO1p29AA93JA0OD9K1221";

       private IRepository repo;
       public PaqueteServicio()
       {
           repo = RestService.For<IRepository>(API_BASE_URL);
       }
       public Task<Resultado> Get()
       {
           return repo.GetAllData();
       }
   }

Package.cs
public class Package
{
        [JsonProperty("peso")]
        public string Peso { get; set; }

        [JsonProperty("tracking_number")]
        public string TrackingNumber { get; set; }

        [JsonProperty("contenido")]
        public string Contenido { get; set; }


public class Resultado
  {
      [JsonProperty("results")]
      public Package[] Results { get; set; }
  }


Main:
class MainViewModel : BaseViewModel
   {
       private readonly PaqueteServicio paqueteServicio;
       private List<Package> paqueteList;
       public List<Package> PaqueteList
       {
           get => paqueteList;
           set
           {
               paqueteList = value;
               RaisePropertyChanged();
           }
       }
       public ICommand ClickCommand => new Command(ClickCommandExecute);

       private async void ClickCommandExecute()
       {
           var response= await paqueteServicio.Get();  //This line is the one with the Error
           PaqueteList = response.Results.ToList();
       }

       public MainViewModel()
       {
           paqueteServicio = new PaqueteServicio();
       }
   }
