+1 Removing helped, thanks.
I can look into fixing this if no-one else has already made a start on it?
feel free to take it, thanks!

Ok, I think I have an understanding of what is happening call to is storing credentials in a json file in a known location. a subsequent credential-requiring kubectl command, the GCP plugin is being loaded, and the application default credentials are being exchanged for a token. That token is then cached in the .kube/config file. So where do things go wrong? As far as I can tell, if I switch to a cluster-2 without refreshing the application default credentials from it's separate account, those existing credentials will still be exchanged successfully for an oauth2 token and cached against cluster-2. Those tokens will then fail against a call to cluster-2 - because they were intended for cluster-1. The only sure-fire fix I can think of would be to ensure the application default credentials client ID is stored in users[].user.authprovider. Doing this would at least enable the ability to verify that the default credentials were valid for that particular cluster, and if not, prompt the user with a message to correctly aquire the application default credentials for it. Lets call this option 1. Of course, there is a problem here with determining what the Client ID is in the first place. I think this would require that a call to would store the client ID in the generated config. This would require exposing the client id from oauth2/google. Otherwise, perhaps storing the client ID the first time around would be enough - assuming the user at least manages to authenticate successfully against the cluster in the first instance. Then only oauth2/google would require a change, and not the gcloud command. The other option (option 2) would be, upon failure, check if is true and if-so, prompt the user that their application default credentials may be invalid for the target cluster, and to either prompt or clear the currently cached credentials in .kube/config. This would probably mean extending the auth provider interface such that a function may be provided that can be called upon failure that enables the auth provider plugin to do some checking of the state and to provide a reasonable message as to what might be wrong with the credentials that have been provided. I feel like option 2 is probably the better option in the long term. Different auth plugins are likely to have different failure modes. Providing a way to communicate back to the user about possible edge cases seems a little more flexible. Any thoughts?

edit: On closer inspection this seems possible by wrapping the oauth2.Transport call in WrapTransport. I would then be able to check for an authorization failure and provide a reasonable error message based on the existing configuration.
Just come across this, its particularly strange to have to edit the config file, when there is a folder in the folder.
Is it really fixed? I still can reproduce it on k8s 1.14 with description provided in initial comment.
I also reproduced this, unfortunately. Tried to use kubectl to access a cluster from an unauthorised account. Then, switched to the authorised account but the invalid authentication was cached. To resolve it, I set the to an expired date.
Believe I'm hitting this issue as well
I just ran into this as well, gcloud 311.0.0, kubectl 1.18.6.
I've got the same issue. I need to change the expiry time to 1 year back as pointed out.
Solution that usually works for me So it will use different credentials when switching contexts
You'll need  installed ().
