Failed to refresh the kubeconfig token: Operation returned an invalid status code 'BadGateway'

Describe the bug Im getting the below error when trying to configure Bridge to kubernetes

Failed to refresh the kubeconfig token: Operation returned an invalid status code 'BadGateway'

To Reproduce Install bridge to kubernetes extension in vscode and try to configure it

Ours is a private kubernetes cluster that runs in our datacentres, and we manage it.

Not sure why the extension is trying to refresh the token as we have a separate login process to get a new token.Our k8s token is a long lived token,so its not required to refresh it.

Thanks @hirannair for opening this issue. When we "refresh credentials", we actually delegate that operation to kubectl:

We make a simple call through kubectl (kubectl get pods -n <YOUR_NAMESPACE>).
If we get a reply from kubectl, we know that the token is valid and we continue.
If we enter kubectl's signin flow, then we display a UI to the user to make it work.

In the case you describe, it sounds like we're having troubles with the reply we get from kubectl.

Would it be possible for you to run kubectl get pods -n <YOUR_NAMESPACE> for the same cluster you use with Bridge to Kubernetes, and let me know what response you get?

Thanks @daniv-msft for that quick response.

$ kubectl get pods

Im able to get the list of pods through kubectl command line and kubernetes extension in vscode

Thanks @hirannair for your reply. I investigated more this issue, and it's possible that it comes from the version of the C# KubernetesClient library we use. We're using a version that isn't the latest, and it's possible this version is the one returning the BadGateway error in your case.

We're working on integrating with their latest version to determine if it helps with your case. Would you be willing to try beta bits of our extension including this change? I can provide full instructions once the fix is available (we're trying to get it done by tomorrow).

@daniv-msft Thanks for the response.Sure,Happy to test the beta version of the extension if you can provide the instructions on how to get it running

(+ @amsoedal who worked on increasing our dependency's version) @hirannair Thanks! We're working to provide this to you tomorrow.

Hi @hirannair, I've posted the steps here (https://github.com/microsoft/mindaro/issues/174#issuecomment-879313528) on how to test beta bits. Please let us know how it goes for you! :)

Thanks @amsoedal .Still getting the same error

Thanks @hirannair for giving it a try! I confirm you're running the right version of our binaries, so unfortunately it looks like this issue wasn't fixed in the latest version of our dependency. I will open a Github issue on their side to report that and see how we can proceed from here. Before I do, and to make sure I have enough information to open the issue on their repository, could you please reproduce the bug and attach the logs from this folder?

For Windows: %TEMP%/Bridge to Kubernetes
For OSX/Linux: $TMPDIR/Bridge to Kubernetes

I'm interested in the latest bridge-library-*.txt and bridge-mindarocli-*.txt files, that should show the exact exception we get from the C# KubernetesClient. Thanks for your help!
