verifyPinCodeView

yourclass VerifyResetCodeView(APIView):
    permission_classes = [permissions.AllowAny]

    def post(self, request):
        serializer = VerifyResetCodeSerializer(data=request.data)
        if serializer.is_valid():
            reset_code = serializer.validated_data.get('reset_code')

            try:
                pin_reset = PinResetCode.objects.get(reset_code=reset_code)
            except PinResetCode.DoesNotExist:
                return Response({'error': 'Invalid reset code.'}, status=status.HTTP_400_BAD_REQUEST)
            
            if pin_reset.is_expired():
                return Response({'error': 'Reset code expired.'}, status=status.HTTP_400_BAD_REQUEST)

            # Store reset code and email in the session
            request.session['reset_code'] = reset_code
            request.session['email'] = pin_reset.email
            request.session.save()  # Explicitly save the session

            # Debugging statements
            print(f"Storing - Reset Code: {reset_code}, Email: {pin_reset.email}")
            print(f"Stored Session Data - Reset Code: {request.session.get('reset_code')}, Email: {request.session.get('email')}")

            return Response({'message': 'Reset code is Verified. You can now set your new PIN.'}, status=status.HTTP_200_OK)

        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

SetNewPin code view

class SetNewPinView(APIView):
    permission_classes = [permissions.AllowAny]

    def post(self, request):
        serializer = SetNewPinSerializer(data=request.data)
        if serializer.is_valid():
            new_pin = serializer.validated_data.get('new_pin')
            confirm_new_pin = serializer.validated_data.get('confirm_new_pin')

            # Retrieve reset code and email from session
            reset_code = request.session.get('reset_code')
            email = request.session.get('email')

            # Debugging information
            print(f"Session data - Reset Code: {reset_code}, Email: {email}")

            # Ensure reset code and email are present
            if not reset_code or not email:
                return Response({'error': 'Reset code and email not found in session.'}, status=status.HTTP_400_BAD_REQUEST)
            
            # Check if new PINs match
            if new_pin != confirm_new_pin:
                return Response({'error': 'New PIN and confirm new PIN do not match.'}, status=status.HTTP_400_BAD_REQUEST)
            
            try:
                pin_reset = PinResetCode.objects.get(email=email, reset_code=reset_code)
            except PinResetCode.DoesNotExist:
                return Response({'error': 'Invalid reset code.'}, status=status.HTTP_400_BAD_REQUEST)
            
            if pin_reset.is_expired():
                return Response({'error': 'Reset code expired.'}, status=status.HTTP_400_BAD_REQUEST)
            
            user = get_object_or_404(Employee, email=email)
            user.set_password(new_pin)
            user.save()

            pin_reset.delete()

            # Clear session data
            request.session.pop('reset_code', None)
            request.session.pop('email', None)

            return Response({'message': 'PIN reset successful.'}, status=status.HTTP_200_OK)

        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

Response that I'm getting from postman while testing is this:

{
    "error": "Reset code and email not found in session."
}

I tried everything like added debugging steps everything. How to fix this?
