Bad Request Error in VendorOrders().submit_acknowledgement()

Describe the bug When I call submit_acknowledgement, I get an error message saying that invalid content was found in the body of request. Even though I do not add marketplaceIds, it seems like self._request() adds it to the body before sending a request to API.

Error Message

sp_api.base.exceptions.SellingApiBadRequestException: [{'code': 'InvalidInput', 'message': "Invalid content was found starting with element 'marketplaceIds'. One of '{acknowledgements}' is expected.", 'details': ''}, {'code': 'InvalidInput', 'message': 'MarketplaceIds', 'details': ''}]

To Reproduce

Here is the code used to call Amazon Vendor SP-API:

with open("ack_body.json", ) as file:
      obj = json.load(file)
 
res = VendorOrders(account="VC").submit_acknowledgement(body=obj)

This is the acknowledgement object that was created according to Amazon Vendor SP-API guidelines:

                    ]
                }
            ]
        }
    ]
}

Expected behavior

I expect this API call to return an ApiResponse with res.payload that includes transactionId. I can then use transactionId to check the request status later.
