Feed Client - Resource not found 404

Problem

When using the Feed Client, the client raises an exception which shows:

azure.devops.exceptions.AzureDevOpsClientRequestError: The resource cannot be found. Operation returned a 404 status code.

Minimal example:

from msrest.authentication import BasicAuthentication
import os

if __name__ == "__main__":
    org = os.environ.get('AZDO_ORG_SERVICE_URL')
    token = os.environ.get('AZDO_PERSONAL_ACCESS_TOKEN')
    credentials = BasicAuthentication('', token)

    from azure.devops.v6_0.feed.feed_client import FeedClient
    feed_client = FeedClient(base_url=org, creds=credentials)
    feed_client.get_feeds()

Other clients like Core are working without any problems.
The permissions of the token are not limited and I am the owner of my test organization.

Enabling debugging output of logging leads to:
DEBUG:azure.devops.client:API resource location c65009a7-474a-4ad1-8b42-7d852107ef8c is not registered on https://dev.azure.com/[Removed].

Commencez par l’exemple minimal de FeedClient utilisant azure.devops.v6_0.feed.feed_client et activez la journalisation de débogage de azure.devops.client pour reproduire le message indiquant que l’emplacement de ressource n’est pas enregistré. Suivez FeedClient.get_feeds et comparez-le à un client fonctionnel ; le travail est terminé lorsque get_feeds ne renvoie plus 404 pour une organisation et un token valides.
