This message occurs when an Istio or Kubernetes resource has an Istio annotation that has been deprecated by the Istio team.
How to resolve
It is likely the annotation will stop taking affect when the Istio control plane is upgraded. Before upgrading, remove or replace this annotation with a supported replacement.
Consult the Istio annotation documentation for a list of Istio annotations.
The Istio release announcements may include advice or suggested replacements for deprecated Istio annotations.
