[Python client] list_by_endpoint is buggy

After bumping svix Python client from 1.62 to 1.82 in [swh-webhooks](https://gitlab.softwareheritage.org/swh/devel/swh-webhooks), some of our unit tests are failing when calling the `list_by_endpoint` wrapper. The issue can be reproduced by applying the following diff: ```diff diff --git a/python/tests/test_client.py b/python/tests/test_client.py index 52d54681..2139a526 100644 --- a/python/tests/test_client.py +++ b/python/tests/test_client.py @@ -235,3 +235,5 @@ def test_svix_message_create( assert message_out.event_type == event_type.name if with_channel: assert message_out.channels == [channel] + + assert svix_api.message_attempt.list_by_endpoint(svix_app_uid, endpoint_uid) ``` The modfied test then outputs the following: ``` _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ self = <svix.api.message_attempt.MessageAttempt object at 0x73b6b8d416d0>, app_id = 'e8a4225b-3568-594d-823e-db4cf110484e', endpoint_id = '7b4d441d-6b11-5cfb-acef-fc1d08583635' options = MessageAttemptListByEndpointOptions(limit=None, iterator=None, status=None, status_code_class=None, channel=None, tag=None, before=None, after=None, with_content=None, with_msg=None, event_types=None) def list_by_endpoint( self, app_id: str, endpoint_id: str, options: MessageAttemptListByEndpointOptions = MessageAttemptListByEndpointOptions(), ) -> ListResponseMessageAttemptOut: """List attempts by endpoint id Note that by default this endpoint is limited to retrieving 90 days' worth of data relative to now or, if an iterator is provided, 90 days before/after the time indicated by the iterator ID.

""" response = self._request_sync( method="get", path="/api/v1/app/{app_id}/attempt/endpoint/{endpoint_id}", path_params={ "app_id": app_id, "endpoint_id": endpoint_id, }, query_params=options._query_params(), header_params=options._header_params(), ) > return ListResponseMessageAttemptOut.model_validate(response.json()) E pydantic_core._pydantic_core.ValidationError: 1 validation error for ListResponseMessageAttemptOut E data.0.statusText E Field required [type=missing, input_value={'url': 'http://172.17.0....12-08T13:09:44.875289Z'}, input_type=dict] E For further information visit https://errors.pydantic.dev/2.11/v/missing ../svix/api/message_attempt.py:341: ValidationError ``` It seems the client expects a `status_text` field to be returned by the server but this is not the case (with open source version only ?).
