Hey,
sorry to hear you’re running into issues.
We are aware of a few minor problems with the TLS configuration of the validation hook in the operator and we’re going to fix them with an upcoming release.
In the meantime you can simply disable the hook by also specifying --set operator.admissionHookEnabled=false in your helm upgrade command.
Note that you will also have to first run a kubectl delete validatingwebhookconfigurations to delete the existing webhook configuration, so the subsequent helm upgrade command will be able to patch the cluster resource.
Best regards,
Simon
