Hi I'm working with pulumi python, after using

k8s.yaml.ConfigFile

and

k8s.yaml.ConfigGroup

for a few months with no issues, I'm currently seeing an issue when previewing a new stack with these elements. this is a stuck trace.

error: Traceback (most recent call last):

    TypeError: 'NoneType' object is not subscriptable
    error: an unhandled error occurred: Program exited with non-zero exit code: 1

removing these elements removes the issue.I'm using pulumi 3.32.1 with this is the k8s pluging when running

pulumi plugin ls

kubernetes                resource  3.20.3   78 MB   2 hours ago  2 hours ago
kubernetes                resource  3.20.2   78 MB   2 hours ago  2 hours ago
kubernetes                resource  3.19.0   79 MB   2 hours ago  2 hours ago

What can I do to fix this?

please file an issue

workaround

self.k8s_provider = k8s.Provider(
            f"{self.resource_name}-kubeconf-provider",
            kubeconfig=None if pulumi.runtime.is_dry_run() else args.kubeconfig,
            opts=self.default_ops,
        )
