I have kubernetes configuration file set up to access multiple clusters which looks like the following with clusters, users and contexts sections for each cluster.

myk8sconfig.yaml

apiVersion: ""
kind: ""
clusters:
    - name: mycluster
      cluster:
        server: https://<mycluster IP>:443
        certificate-authority-data: <my cluster certificate>
        
--------------------------------------</snip>------------------------------------------

users:
    - name: mycluster-user
      user:
        exec:
            apiVersion: client.authentication.k8s.io/v1beta1
            command: ./mycustom_token_generator_cmd
            args:
                - token_gen_args
            env: []
            
--------------------------------------</snip>------------------------------------------

contexts:
    - name: mycluster-context
      context:
        cluster: mycluster
        user: mycluster-user

I can use the above config to run any kubectl command as the following without any errors

kubectl get pod --all-namespaces -o json  \
    --kubeconfig ~/.kube/myk8sconfig.yaml  \
    --context mycluster-context

But the same configuration file fails to get authorization when used in python sdk like the following

from kubernetes import client, config

config.load_kube_config(
    config_file=HOME_DIR + "/.kube/myk8sconfig.yaml",
    context="mycluster-context"
)

config.debug = True

v1=client.CoreV1Api()
ret = v1.list_pod_for_all_namespaces(watch=False)

It gives me the following error

Reason: Unauthorized
HTTP response headers: HTTPHeaderDict({'Audit-Id': '172c4e92-7e7a-45a1-blah-blah', 'Cache-Control': 'no-cache, private', 'Content-Type': 'application/json', 'Date': 'Fri, 07 Feb 2025 18:19:28 GMT', 'Content-Length': '129'})
HTTP response body: {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"Unauthorized","reason":"Unauthorized","code":401}

As you can see I tried config.debug = True but that didn't yield any additional information.

I am not sure how to debug this further and need some help.

Thank you in advance for your help.
