Getting this error from a deployed pod:

Kubernetes is EKS on AWS.

I believe this is because of an incompatibility of the kubernetes client library being used. https://github.com/kubernetes-client/python#compatibility-matrix

@strongpauly Could you try changing the version of the kuberentes client in the requirements.py file so that it matches your server version. Since your server is version 1.13 I think you should be using client-python 9.0.

I've been seeing the same error sporadically after using client-python 10.0 with a 1.13 server. It seems that this error may cause the pod to restart, but at some point it stay up but reports no events to sentry. Deleting the pod and having a new one come up fixes the problem for me.

Hey, Thanks for reporting! The agent is being rewritten in Go now, so we'll just close this one.
