Valid KnowledgeBaseId and SubscriptionKey not provided

问题

I need help, after migrating to the new QNAMaker, im now getting an error: Valid KnowledgeBaseId and SubscriptionKey not provided. Use QnAMakerServiceAttribute or set fields on QnAMakerDialog. What am i missing? Subscription Key and KnowledgebaseID was already added. I simply followed the sample http request upong publishing in the qnamaker portal.

using Microsoft.Bot.Builder.Dialogs;
using QnAMakerDialog;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Threading;
using Microsoft.Bot.Connector;
using System.Threading.Tasks;
using Microsoft.Bot.Builder.CognitiveServices.QnAMaker;

namespace TEST.Dialog
{
[Serializable]

[QnAMaker(authKey:"013ffd97-XXXX-XXXX-981f-ea298085591c", knowledgebaseId:"f81ce668-XXXX-XXXX-XXXX-ad20c5f4d3fa", endpointHostName:"https://XXXX.azurewebsites.net/qnamaker")]
public class QnADialog : QnAMakerDialog<object>
{
   public async Task StartAsync(IDialogContext context)
    {
        context.PrivateConversationData.TryGetValue("Name", out name);
        await context.PostAsync($"Hello {name}. The QnA Dialog was started. Ask a question.");
        context.Wait(MessageReceivedAsync);

    }

    public async Task DefaultMatchHandler(IDialogContext context, string originalQueryText, QnAMakerResult result)
    {
        try
        {
            // ProcessResultAndCreateMessageActivity will remove any attachment markup from the results answer
            // and add any attachments to a new message activity with the message activity text set by default
            // to the answer property from the result
           // var messageActivity = ProcessResultAndCreateMessageActivity(context, ref result);
            if (result.Score > 30 && result.Answer != NOMATCH)
            {
                await context.PostAsync(result.Answer);
                context.Wait(this.MessageReceived);
                return;
            }
            else
            {
                await context.Forward(new RootLuisDialog(), DialogsCompleted, context.Activity, CancellationToken.None);
            }
        }
        catch (Exception ex)
        {
            throw;
        }

    }

    public override async Task NoMatchHandler(IDialogContext context, string originalQueryText)
    {
        try
        {
            await context.Forward(new RootLuisDialog(), DialogsCompleted, context.Activity, CancellationToken.None);
        }
        catch (Exception ex)
        {
            throw;
        }

    }

    private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)
    {
        var activity = await result as Activity;

        // calculate something for us to return
        int length = (activity.Text ?? string.Empty).Length;

        // return our reply to the user
        //await context.PostAsync($"You sent {activity.Text} which was {length} characters");

        context.Wait(this.MessageReceived);
        return;
    }

     private async Task DialogsCompleted(IDialogContext context, IAwaitable<object> result)
    {
        var success = await result;
        //if (!(bool)success)
        //    await context.PostAsync("I'm sorry. I didn't understand you.");

        //context.UserData.Clear();
        context.Wait(MessageReceived);
    }


    [QnAMakerResponseHandler(30)]
    public async Task LowScoreHandler(IDialogContext context, string originalQueryText, QnAMakerResult result)
    {
        //await context.PostAsync($"I found an answer that might help: {result.Answer}");
        await context.Forward(new RootLuisDialog(), DialogsCompleted, context.Activity, CancellationToken.None);
        //context.Wait(MessageReceived);
    }
}
}

RootDialog that calls QNAMaker:

using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Builder.FormFlow;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Threading;
using System.Threading.Tasks;
using System.Web;

namespace Test.Dialog
{
[Serializable]
public class RootDialog : IDialog<object>
{
    public string name = string.Empty;
    public Task StartAsync(IDialogContext context)
    {
        context.Wait(MessageReceivedAsync);
        return Task.CompletedTask;
    }


     private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)
    {
        try
       {
            //Some User Code that retreives user via PrivateConversationData




            //Calls QNADialog

            context.Call(new QnADialog(), MessageReceivedAsync);
       }
}

}

My Version of CognitiveServices: Microsoft.Bot.Builder.CognitiveServices.1.1.7 Bot Builder,Bot Connector :3.15.2.2 QNADialog: 1.2.0

It seems that you are using QnAMakerDialog with QnA Maker service v4.0, but in description of NuGet package QnAMakerDialog and GitHub readme of QnAMakerDialog (updated to work with QnA Maker v3 API), we can find that this QnAMakerDialog nugget package can work with v3 of the QnA Maker API, not QnA Maker service v4.0.

To work with QnA Maker service v4.0, as Nicolas R said, you can use this NuGet package: Microsoft.Bot.Builder.CognitiveServices to create your QnAMakerDialog.

[Serializable]
public class QnADialog : QnAMakerDialog
{
    public QnADialog() : base(new QnAMakerService(new QnAMakerAttribute("{qnaAuthKey_here}", " {knowledgebaseId_here}", "No good match in FAQ.", 0.5, 1, "https://xxxx.azurewebsites.net/qnamaker")))
    { }

    //other code logic
}

As explained on the Generally Available announcement, you can still use Microsoft.Bot.Builder.CognitiveServices package in your code: the code has been changed to handle bot v1 to v3 calls and new v4 (GA version).

You just have to add the necessary information, that is to say the endpoint hostname as previously it was hosted on Microsoft side.

So your dialog code will look like the following (see Github official sample here):

[Serializable]
[QnAMaker("set yout authorization key here", "set your kbid here", <score threshold>, <number of results>, "endpoint hostname")]
public class SimpleQnADialog : QnAMakerDialog
{
}
