If you get this error after applying the DynaKube custom resource, your Kubernetes API server may be configured with a proxy. You need to exclude https://dynatrace-webhook.dynatrace.svc from that proxy.

Hi, everyone!
re: "undefined" error for x509 certificate check from the comment above by Ashok


The issue was the old webhook deployment that is actually deployed outside of the dynatrace namespace,

resulting in some "leftovers" from the previous Operator version installations

and this was also preventing the new Operator version (0.15.0) from being installed from the Operator Hub.


To resolve the issue, we deleted all the deployed resources using

kubectl/oc delete -f openshift.yaml

Afterwards, the installation was completed successfully.

I hope this helps anyone stumbling into similar issues with the webhook.

Sincerest, Andrew
