get_labels asking for value not found in Amazon documentation

[godlyatheist]

Describe the bug
When calling get_labels, error message "sp_api.base.exceptions.SellingApiBadRequestException: [{'code': 'InvalidInput', 'message': "1 validation error detected: Value null at 'cartonIdList' failed to satisfy constraint: Member must not be null", 'details': ''}]". cartonIdList is not a value associated with the getLabels operation according to documentation. The code below used to work without error.

To Reproduce

`from sp_api.base import Marketplaces
from sp_api.api import FulfillmentInbound

credentials = dict(refresh_token='token', lwa_app_id='app_id', lwa_client_secret='secret')

label_blob = FulfillmentInbound(credentials=credentials, marketplace=Marketplaces.US).get_labels(
shipment_id = 'FBA0000000',
PageType = 'PackageLabel_Thermal',
LabelType = ['UNIQUE','PALLET'] )
print(label_blob['DownloadURL'])
`
Expected behavior
No error regarding cartonIdList, returns a URL

Windows 10 build 19045 VSCode 1.85.1

Additional context

I haven't worked with this endpoint for some time, but if I remember correctly, if the code was working, it must have been for a shipment created with something other than a carton feed. The value you need to pass for this kind of shipment should be this
