error reading InstanceGroup %q: %v

Error message

error reading InstanceGroup %q: %v

What it means

RunEditInstanceGroup fetched the named instance group from the state store and the API call itself errored (not a clean not-found): store unreachable, permissions, or server error. The cluster lookup and channel load already succeeded.

Solutions

  1. Inspect the wrapped error for the state store failure reason
  2. Verify state store access and credentials
  3. Confirm the cluster's instance groups are readable (kops get ig)
Defensive patterns

Strategy: try-catch
