[Sabareesh-CKT]

Hi Team
I am running the minikube started with kvm2 enabled
ran the v0.0.16 retina version using helm with all the http capture enabled. I see both the retina-agent and retina up in kubernetes

but seeing couple of errors

how to resolve the above issue I am running this in GCP VM Debian linux instance. any configurations need to be done to fix this ?

Iam running my application in default namespace and hitting the API's.
I am checking the retina agent logs to see whether the HTTP request and response is getting captured or not but don't any see data around that.
