CompleteSale doesn't mark the order as shipped.

response = API.execute('CompleteSale',
                                    {
                                            'FeedbackInfo':feed_back_info,
                                            "ItemID": message['listing_id'],
                                            "OrderID": message['order_id'],
                                            "TransactionID": message['transaction_id'],
                                            "Shipped": 'true',
                                        })

response.dict()
{'Timestamp': '2023-08-11T13:48:44.489Z', 'Ack': 'Success', 'Version': '1321', 'Build': 'E1289_CORE_APIXO_19220561_R1'}
The response status code is 200 but it doesn't mark the order as shipped on ebay at all.
Note: it used to work before but it just broke today for no reason.
