failed to get kind for object

Error message

failed to get kind for object

What it means

Wraps the Kind() lookup failure while grouping manifest objects by GroupKind for pruning. Fires when an object in the addon manifest cannot yield its kind, i.e. malformed object metadata that prevents classifying it for prune scoping.

Solutions

1. Fix the kind field of the malformed object in the addon manifest
2. Validate the manifest with kubectl dry-run before applying
3. Correct or remove the offending manifest and re-run Normalize
