From user:

im kinda confused by this issue when sky jobs launch
File "/Users/xxx/workspace/skypilot/sky/clouds/kubernetes.py", line 577, in validate_region_zone
raise ValueError(
ValueError: Context xyz not found in kubeconfig. Kubernetes only supports context names as regions. Available contexts: ['abc', 'def']
i don't even have xyz in my ~/.kube/config anymore. where is sky pulling this info from?

If the jobs controller was launched on a context that got removed later, users will run into this error. The error message needs to be more helpful.
