no previous context found
Error message
no previous context found
What it means
Guard error in swapContext: readLastContext returned an empty value, meaning the previous-context state file is missing, empty, or has never been written. `kubectx -s` (swap) can only work after at least one prior `kubectx <NAME>` switch recorded the previous context.

Solutions
- Switch to a context with `kubectx <NAME>` first; afterwards `kubectx -s` can swap back
- Check that the cache file (~/.cache/kubectx/kubectx or XDG_CACHE_HOME) was not deleted
