Microsoft bot V4 Skill Bot 在 SendActivityAsync function 回复 Root bot 时响应 500（内部错误）

Question

I'm trying Master and Skill bot functionality by calling Microsoft Sample EchoSkillBot from Master Bot developed by me. Call reached Skill bot from Master but while Skill bot replying to Master getting the exception "InternalServerError". Additional note I'm using LUIS to route the conversations to respective Skill and QnA.

Code: (Exception thrown at this code)

await turnContext.SendActivityAsync(
           MessageFactory.Text(messageText, 
                               messageText, 
                               InputHints.IgnoringInput), 
           cancellationToken);

Error:

"{"type":"https://tools.ietf.org/html/rfc7231#section-6.6.1","title":"An error occured while processing your request.","status":500,"traceId":"XXXXX"}"

"Operation returned an invalid status code 'InternalServerError'"

Answer 1

I found the root cause for the exception. In startup.cs I had used Bot framework adapter as IBotFrameworkHttpAdapter in one place and other place BotFrameworkHttpAdapter. After fixing this Skill reply worked fine.

   // Create the Bot Framework Adapter with error handling enabled.
   //services.AddSingleton<IBotFrameworkHttpAdapter, AdapterWithErrorHandler>();
     services.AddSingleton<BotFrameworkHttpAdapter, AdapterWithErrorHandler>();
     services.AddSingleton<BotAdapter>(sp => sp.GetService<BotFrameworkHttpAdapter>());  //Added for Skill bot
