error: Apply failed with 1 conflict: conflict with "observability-operator": .spec.logLevel Please review the fields above--they currently have other managers. Here are the ways you can resolve this warning: * If you intend to manage all of these fields, please re-run the apply command with the `--force-conflicts` flag. * If you do not intend to manage all of the fields, please edit your manifest to remove references to the fields that should keep their current managers. * You may co-own fields by updating your manifest to match the existing value; in this case, you'll become the manager if the other manager(s) stop managing the field (remove it from their configuration).
