Ajax not getting sucess reponse from django back-end – Jquery ajax

return JsonResponse({"success": True}, data, status=200)

that line will fail with some error message, because you pass data as a second positional argument. Django documentation tells you that second positional argument is encoder. Since a list with data isn’t an encoder – you will get an error.

Your error would be catched by try/except block. So the execution flow will move to except block – where you return {"success": false} JSON response.

So your code should become like this:

def GetAnswer(request):
    if request.method=='GET' and request.is_ajax():
        question_asked=str(request.GET.get("message_now"))
        try:
            answer=QuestionAnswer.objects.filter(question=question_asked).value_list('answer', flat=True)[0]
            print(answer)
            data={"data":answer}

            return JsonResponse({"success": True, "data": data}, status=200)
        except:

            return JsonResponse({"success": False}, status=400)
    else:
        print("Not Suceess")

Please, refer to this part of documentation for more details https://docs.djangoproject.com/en/3.1/ref/request-response/#jsonresponse-objects

UPDATE (21.09.2020)

You should fix this line:

answer=QuestionAnswer.objects.filter(question=question_asked).value_list('answer', flat=True)[0]

to

answer=QuestionAnswer.objects.filter(question=question_asked).values_list('answer', flat=True)[0]

because there’s no value_list function, but there’s values_list.

UPDATE 2 (21.09.2020)

So the final code should be:

def GetAnswer(request):
    if request.method == 'GET' and request.is_ajax():
        question_asked = request.GET["message_now"]
        try:
            answer = QuestionAnswer.objects.filter(question=question_asked).values_list('answer', flat=True)[0]
            return JsonResponse({"success": True, "answer": answer}, status=200)
        except:
            return JsonResponse({"success": False}, status=400)

and JS code should be modified as well

function chatbotvoice(message) {
  const speech = new SpeechSynthesisUtterance();

  if (message !== null && message !== '') {
    $.ajax({
      url: "http://127.0.0.1:8000/getanswer",
      type: 'GET',
      data: {
        message_now: message
      },
      success: function (data) {
        if (data.success == true){
          speech.text = data.answer;
          window.speechSynthesis.speak(speech);
          chatareamain.appendChild(showchatbotmsg(speech.text));
        } else {
          speech.text = "Oh No!! I don't Know !! I am still learning!! Your question got recorded and answer for your question will be available with me in 24 hours";
          window.speechSynthesis.speak(speech);
          chatareamain.appendChild(showchatbotmsg(speech.text));
        }
      },
      error: function (error) {
        speech.text = "Oh No!! I don't Know !! I am still learning!! Your question got recorded and answer for your question will be available with me in 24 hours";
        window.speechSynthesis.speak(speech);
        chatareamain.appendChild(showchatbotmsg(speech.text));
      },
    });
  }
}
