kubernetes-client python ConfigNode JSON serializable exec_provider fix 2025
Older notes for kubernetes-client__python-2340 can help with context, but they do not fully cover the current failure mode.
Why the common answers are incomplete
The Kubernetes Python client attempts to JSON serialize a ConfigNode in exec_provider configuration.
Convert ConfigNode values to plain dict/list/scalar data before passing exec_provider data to JSON serialization.
The failing object is ConfigNode, so the patch should normalize that wrapper at the kubeconfig boundary.
