authentication within @kubernetes/client-node is not working as expected

i tried to us deno2 and the @kubernetes/client-node to connect to an local kubernetes but i wasnt able to authenticate. i always ended up with an anonymous user. i tried different users and configs in the .kube/config and also with the programatic way. i could not find any problems with code and kubernetes-config so i switched back to nodejs and it worked as expected.
Any ideas on that? Not sure if it is a problem with the library or deno ...
