TypeError: expected string or bytes-like object error for date range in Django

Question

I am trying to filter CartItem objects based on their delivery dates. I define a startfilterdate and an endfilterdate that i format as a string in the same way my delivery_date's are formatted. Not sure what i am doing wrong.

models.py

class CartItems(models.Model):
    restaurant = models.ForeignKey(Restaurant, related_name='restaurant', on_delete=models.CASCADE)
    delivery_date = models.DateField(auto_now_add=False)

views.py

class RestaurantOrders(generics.ListAPIView):
    serializer_class = RestaurantOrderSerializer

    def get_queryset(self):
        restaurant_id = self.kwargs['pk']
        startfilterdate = date.today()
        startfilterdate = startfilterdate.strftime("%Y-%m-%d")
        endfilterdate = date.today()+timedelta(days=9)
        endfilterdate = endfilterdate.strftime("%Y-%m-%d")
        orders = CartItems.objects.filter(restaurant_id = restaurant_id, delivery_date=[startfilterdate,endfilterdate])

Error: TypeError: expected string or bytes-like object

Use range lookup as,

orders = CartItems.objects.filter(..., delivery_date__range=[startfilterdate,endfilterdate])
