error pruning manifest: %w

Error message

error pruning manifest: %w

What it means

In updateAddon, the pruner failed while pruning objects listed in the manifest according to the addon's prune spec. The apply step may have succeeded; this wraps the prune failure, and both errors are accumulated via multierr.

  2. Check that the prune label/field selectors and namespaces in the addon spec are valid
  3. Verify RBAC permissions allow deleting the pruned resources
