az k8s-extension show/update fails with InvalidApiVersionParameter — hardcoded api-version 2023-05-01 no longer valid

[cwedgwood]

Describe the bug

az k8s-extension show and az k8s-extension update fail with InvalidApiVersionParameter because the vendored SDK uses DEFAULT_API_VERSION = '2023-05-01' which has been removed from the supported API versions on some subscriptions.

Error message

ERROR: (InvalidApiVersionParameter) The api-version '2023-05-01' is invalid. The supported versions are '2025-04-01,2025-03-01,2024-10-01-preview,2024-11-01,...'

Source

src/k8s-extension/azext_k8s_extension/vendored_sdks/_source_control_configuration_client.py:

DEFAULT_API_VERSION = '2023-05-01'

Workaround

Use az rest directly with a current API version:

az rest --method GET \
  --url "https://management.azure.com/subscriptions/<sub>/resourceGroups/<rg>/providers/Microsoft.Kubernetes/connectedClusters/<cluster>/providers/Microsoft.KubernetesConfiguration/extensions/<name>?api-version=2024-11-01"

Extension version

k8s-extension 1.7.0

Thank you for opening this issue, we will look into it.

Closing — this was caused by passing a full ARM resource ID path to -g instead of just the resource group name. The CLI misroutes the request to the ARM resource group endpoint (which doesn't know about 2023-05-01) instead of the KubernetesConfiguration endpoint. Not an API version deprecation. Apologies for the noise.
