Question

Here's my current configuration screen:

Answer 1

I'm assuming that you're referring to these docs: QnaMaker - Change Default Answer
They're a little confusing, but they key part is:
You can override this default response in the bot or application code
calling the endpoint.
Where the docs have this image:
What they actually mean is that in the QnAMaker Test Console, you can edit the default answer from your Application Settings. Be sure to Save, Train, and Publish your app or the setting may not show.
There's also kind of a way that you can use this setting for your default answer in a bot:
In Node/JS, your bot will not receive that DefaultAnswer at all. It receives nothing if there isn't a match, so you have to hard code it with something like:
const qnaResults = await this.qnaMaker.getAnswers(context);
// If an answer was received from QnA Maker, send the answer back to the user.
if (qnaResults[0]) {
await context.sendActivity(qnaResults[0].answer);
// If no answers were returned from QnA Maker, show this reply.
// Note: .getAnswers() does NOT return the default answer from the App Service's Application Settings
} else {
const defaultAnswer = 'No QnA Maker answers were found. This example uses a QnA Maker Knowledge Base that focuses on smart light bulbs. To see QnA Maker in action, ask the bot questions like "Why won\'t it turn on?" or "I need help."'
await context.sendActivity(defaultAnswer);
}

Answer 2

When creating an Azure Web Bot, one of the default Web Chat clients is a fork of microsoft's BotBuilder-Samples project, specifically 49 - QnAMaker All Features
The source code for Dialog/QnAMakerBaseDialog.cs defines the constant DefaultNoAnswer:
public const string DefaultNoAnswer = "No QnAMaker answers found.";
And then uses that value when returning a response from GetQnAResponseOptionsAsync:
protected async override Task<QnADialogResponseOptions> GetQnAResponseOptionsAsync(DialogContext dc)
{
var noAnswer = (Activity)Activity.CreateMessageActivity();
noAnswer.Text = DefaultNoAnswer; // <- used right here
var cardNoMatchResponse = (Activity)MessageFactory.Text(DefaultCardNoMatchResponse);
var responseOptions = new QnADialogResponseOptions
{
ActiveLearningCardTitle = DefaultCardTitle,
CardNoMatchText = DefaultCardNoMatchText,
NoAnswer = noAnswer,
CardNoMatchResponse = cardNoMatchResponse,
};
return responseOptions;
}
This particular sample repo doesn't appear to leverage the DefaultAnswer configuration key anywhere.
You can opt to include it when available by updating the noAnswer.Text like this:
- noAnswer.Text = DefaultNoAnswer;
+ noAnswer.Text = this._configuration["DefaultAnswer"] ?? DefaultNoAnswer;
You'll also have to pass in the configuration object through the dependency management system. See this commit for a full example.

Answer 3

Change the line in qamakerBaseDialog.js as below
var noAnswer = ActivityFactory.DefaultNoAnswer;
Remove ActivityFactory. and rebuild the code.
constructor(knowledgebaseId, authkey, host) {
//ActivityFactory.
var noAnswer = DefaultNoAnswer;
var filters = [];
super(knowledgebaseId, authkey, host, noAnswer, DefaultThreshold, DefaultCardTitle, DefaultCardNoMatchText,
DefaultTopN, ActivityFactory.cardNoMatchResponse, filters, QNAMAKER_BASE_DIALOG);
this.id = QNAMAKER_BASE_DIALOG;
}
