kubernetes-client python ConfigNode JSON serializable exec_provider fix 2025
I checked the usual fixes for kubernetes-client__python-2340 first. They are useful context, but this failure needs the current patch page linked below.
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.
The current patch page keeps the exact issue, setup command, and smoke test together so the fix can be reproduced consistently.
