Can you perhaps also share the console output as well?

Hi, I have the same problem here is the console output.

I replicated your dev environment.
The issue seems to be with using Kubernetes version: v1.16.0
That's a fairly recent release, not sure if we should worry about that version as of now.
The current dashboard release v2.0.0-beta4 only claims to support till 1.15 k8s.
And this feature works fine on 1.15

Tkanks for the info.
Do we have ETA on v1.16.0 support?

[anshulahuja98]

I cannot comment on that
@maciaszczykm @floreks can perhaps give better info on this.

It all depends on client-go updating their code to support v1.16.

[zerkms]

Client go DOES support v1.16

Right, I confused it with something else, my apologies.

[floreks]

@zerkms I don't see any official release that would support v1.16 on their github page: https://github.com/kubernetes/client-go#compatibility-matrix

@anshulahuja98 here is the console output and kubernetes-dashboard pod log.

We've established already that it is related to some changes in K8S v1.16. We have to wait for the official release of client-go to support it. Right now we do not.
