Hi @san360 thanks for reporting this. I'll certainly try to look into this, but tbh. it might take some time, I'm not familiar with WSL at all ;). Are you able to try with WSL2 - partially out of curiosity on my side, no idea if that might help, but my colleague mentioned there were many improvements/bugfixes since the WSL1.

As a workaround, I would suggest you try to use docker image. We're not publishing it anywhere yet (tbd soon), but just recently added it to the repo, so just building the image from Dockerfile in the root of this repo should work.

I have the same error, in mac osx and version 0.3.0 and I think is due to a bad kube config, so I've created a PR to avoid the panic and the error is showing up like:

@san360 this should be resolved, would you be able to test latest master on windows to confirm?

I believe this has been resolved, as per above, and covered by tests as well. Closing this issue. In case you experience the same again please comment and we can reopen.
