Panic

[malins]

Hello,

does this provider work with latest Kubernetes version (v1.29.2) and latest Crossplane-Version (1.15.1)?

First, the provider pod is outputting only panic messages:

Second, when creating the namespace-object, the managed resource is created, but there is no status assigned:

Any hints on how to get this provider working are welcome.

Thank you,

This would seem to indicate a problem with the content of the ProviderConfig - have you tested with a known-good ProviderConfig?

Hi, the "current-context" in the kubeconfig was wrong.
Thanks.
