Error parsing version %s: %v

Error message

Error parsing version %s: %v

What it means

Panicked from Cluster.IsKubernetesGTE when the version argument passed to the GTE comparison itself fails to parse — distinct from the cluster-version panic, this fires when the caller-supplied comparison string (e.g. "1.27" style or a typo like "v1.x") is not valid semver. The helper's contract panics on invalid input so the offending version string is printed with the parse error.

Solutions

1. Pass a fully-qualified valid version (e.g. "1.27.0", not "1.27") to IsKubernetesGTE
2. Fix the hardcoded version constant at the call site reported by the panic
