getting machine type info: %w

Error message

getting machine type info: %w

What it means

Wrapped error propagated from guessMachineTypeInfo inside InstanceTemplate.mapToGCE. The helper derives migration support from the machine-type family prefix; failure means the machine type string was malformed or could not be split into a family (e.g. empty or non-standard MachineType in the spec).

Solutions

1. Verify the machine type in the instance template spec is a valid GCE type name (e.g. n1-standard-2)
2. Check the wrapped error for the specific parse failure
3. Correct the cluster spec's machine type and re-run
