Description

I had to rotate my certificates using kubectl because:

⌛  Starting certificate rotation
ℹ️  generating fresh certificates
ℹ️  Updating certifcates in your Kubernetes cluster
ℹ️  Dapr control plane version 1.13.0-mariner detected in namespace dapr-system
❌  certificate rotation failed: chart "dapr" version "1.13.0-mariner" not found in https://dapr.github.io/helm-charts repository

And I followed the documentation but missed dapr-sidecar-injector. Before I restarted my sidecar injector deployment, I restarted my application and noticed that the sidecar injector did not insert sidecars, so my application broke.

Good catch. Should also add the scheduler server to this list.
