BotAuth与Azure表存储错误

Question

我正在使用BotAuth nuget包登录我的机器人用户。最近，我按照https://docs.microsoft.com/en-us/bot-framework/dotnet/bot-builder-dotnet-state-azure-table-storage中提到的步骤执行Azure Table存储以存储和管理机器人状态数据。

我的Global.asax.cs文件看起来像这样：

public class WebApiApplication : System.Web.HttpApplication 
{ 
    protected void Application_Start() 
    { 

     var store = new TableBotDataStore(CloudStorageAccount.DevelopmentStorageAccount); 
     Conversation.UpdateContainer(builder => 
     { 

      builder.Register(c => store) 
       .Keyed<IBotDataStore<BotData>>(AzureModule.Key_DataStore) 
       .AsSelf() 
       .SingleInstance(); 

      builder.Register(c => new CachingBotDataStore(store, 
         CachingBotDataStoreConsistencyPolicy 
         .ETagBasedConsistency)) 
         .As<IBotDataStore<BotData>>() 
         .AsSelf() 
         .InstancePerLifetimeScope(); 
     }); 
     GlobalConfiguration.Configure(WebApiConfig.Register); 
    } 
} 

而且MessagesController是一样的人在BOT模板：现在

[BotAuthentication] 
public class MessagesController : ApiController 
{ 
    /// <summary> 
    /// POST: api/Messages 
    /// Receive a message from a user and reply to it 
    /// </summary> 
    public async Task<HttpResponseMessage> Post([FromBody]Activity activity) 
    { 
     if (activity.Type == ActivityTypes.Message) 
     { 
      await Conversation.SendAsync(activity,() => new Dialogs.RootDialog()); 
     } 
     else 
     { 
      HandleSystemMessage(activity); 
     } 
     var response = Request.CreateResponse(HttpStatusCode.OK); 
     return response; 
    } 

    private Activity HandleSystemMessage(Activity message) 
    { ...... } 
} 

，在测试它，我得到如预期的登录卡和点击并完成授权过程后，我在浏览器中出现以下错误：

{ 
"message": "An error has occurred.", 
"exceptionMessage": "Object reference not set to an instance of an object.", 
"exceptionType": "System.NullReferenceException", 
"stackTrace": " at BotAuth.AADv1.ADALAuthProvider.<GetTokenByAuthCodeAsync>d__4.MoveNext()\r\n--- End of stack trace from previous location where exception was thrown ---\r\n at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\r\n at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\r\n at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult()\r\n at BotAuth.Controllers.CallbackController.<Callback>d__3.MoveNext()" 
} 

我错过了什么？它是一些autofac模块注册。有没有人有任何工作示例。

正如@FeiHan在评论中指出的那样，这是richdizz/BotAuth中的一个公开问题。 - "Enabling custom state service causes authentication failure"。

此问题已得到修复MicrosoftDX/botauth，因此最好使用这一个，而不是
