Botframework-solutions: Bot.Builder.Community.Adapters.Alexa não funciona com o VA

Qual projeto é afetado?

Assistente virtual.

Em que idioma está isso?

C #

O que acontece?

BotBuilder.Community.Adapters.Alexa não parece funcionar com o VA.

Quais são as etapas para reproduzir esse problema?

Siga as instruções aqui: - https://github.com/BotBuilderCommunity/botbuilder-community-dotnet/tree/develop/libraries/Bot.Builder.Community.Adapters.Alexa

1) No Startup.cs, adicionei os seguintes pacotes NuGet:

Bot.Builder.Community.Adapters.Alexa;
Bot.Builder.Community.Adapters.Alexa.Integration.AspNet.Core;
Bot.Builder.Community.Adapters.Alexa.Middleware;

Antes deste código

            // Configure bot
            services.AddTransient<IBot, DialogBot<MainDialog>>();

Eu adicionei:

            // Registering the AlexaHttpAdapter
            services.AddSingleton<IAlexaHttpAdapter>((sp) =>
            {
                var alexaHttpAdapter = new AlexaHttpAdapter(validateRequests: true)
                {
                    OnTurnError = async (context, exception) =>
                    {
                        await context.SendActivityAsync("Sorry, something went wrong. Please try again later." + context + " Exception:" + exception);
                    },
                    ShouldEndSessionByDefault = true,
                    ConvertBotBuilderCardsToAlexaCards = false,
                };
                alexaHttpAdapter.Use(new AlexaIntentRequestToMessageActivityMiddleware());
                return alexaHttpAdapter;
            });

            services.AddSingleton<AlexaIntentRequestToMessageActivityMiddleware>();

2) Criou um controlador Alexa:

using Bot.Builder.Community.Adapters.Alexa.Integration.AspNet.Core;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Bot.Builder;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace GuideDogs_VA.Controllers
{
    [Route("api/skillrequests")]
    [ApiController]
    public class AlexaBotController : ControllerBase
    {
        private readonly IAlexaHttpAdapter _adapter;
        private readonly IBot _bot;

        public AlexaBotController(IAlexaHttpAdapter adapter, IBot bot)
        {
            _adapter = adapter;
            _bot = bot;
        }

        [HttpPost]
        public async Task PostAsync()
        {
            await _adapter.ProcessAsync(Request, Response, _bot);
        }
    }
}

3) Criou uma habilidade Alexa usando o seguinte JSON:

{
    "interactionModel": {
        "languageModel": {
            "invocationName": "guide dogs",
            "intents": [
                {
                    "name": "GetUserIntent",
                    "slots": [
                        {
                            "name": "phrase",
                            "type": "phrase"
                        }
                    ],
                    "samples": [
                        "{phrase}"
                    ]
                },
                {
                    "name": "AMAZON.FallbackIntent",
                    "samples": []
                },
                {
                    "name": "AMAZON.NavigateHomeIntent",
                    "samples": []
                },
                {
                    "name": "AMAZON.CancelIntent",
                    "samples": []
                },
                {
                    "name": "AMAZON.HelpIntent",
                    "samples": []
                },
                {
                    "name": "AMAZON.StopIntent",
                    "samples": []
                }
            ],
            "types": [
                {
                    "name": "phrase",
                    "values": [
                        {
                            "name": {
                                "value": "hi there Alexa"
                            }
                        },
                        {
                            "name": {
                                "value": "you are just going to repeat what I said aren't you"
                            }
                        },
                        {
                            "name": {
                                "value": "what colour is the sky?"
                            }
                        }
                    ]
                }
            ]
        }
    }
}

O que você esperava que acontecesse?

Ao testar a habilidade Alexa por meio do console do desenvolvedor Alexa ou por meio de um dispositivo Alexa, para que ela responda, mas infelizmente acaba chamando OnEventSync () mesmo que o tipo de atividade seja do tipo mensagem.

Você pode compartilhar algum registro, saída de erro, etc.?

System.NullReferenceException lançada do arquivo MainDialog.cs:

Alguma captura de tela ou contexto adicional?
