Incorrect filtering

[gonewiththeway]

Hello. I am trying to use the python library in one of my apps. However, it throws an error if I provide any parameter other than departure_date, destination and origin.

In the documentation, and the example in documentation, its clearly mentioned that arrival_time and departure_time can also be param in slice.

FWIW, I commented the error, and it worked - which means backend is alright, but the python code is not working.

Official Documentation:

from duffel_api import Duffel

duffel = Duffel(access_token=YOUR_ACCESS_TOKEN)

duffel.offer_requests.create().cabin_class("economy")

.passengers([
   {
      "family_name": "Earhart",
      "given_name": "Amelia",
      "loyalty_programme_accounts": [
         {
            "account_number": "12901014",
            "airline_iata_code": "BA"
         }
      ],
      "type": "adult"
   },
   {
      "age": 14
   },
   {
      "fare_type": "student"
   },
   {
      "age": 5,
      "fare_type": "contract_bulk_child"
   }
])
.slices([
   {
      "origin": "LHR",
      "destination": "JFK",
      "departure_time": {
         "to": "17:00",
         "from": "09:45"
      },
      "departure_date": "2020-04-24",
      "arrival_time": {
         "to": "17:00",
         "from": "09:45"
      }
   }
])
.execute()
