  "message": "Fail apply-object on change /meta when missing patch-set\n\nThe execution of apply-object of changes /meta ref has no\nguarantee to be executed after the successful replication of\nthe associated patch-set.\n\nUpdating the repository with the change /meta pointing to\na missing patch-set, albeit legal from a repo\u0027s perspective,\nit would cause errors in Gerrit at multiple levels:\n- the change screen would not render and produce 500s\n- the reindex may fail\n- the comments may succeed on repo but fail to be reindexed\n\nIt is way better to fail the apply-object and let the\nreplication to fallback to async fetch rather than putting\nthe change in an inconsistent state.\n\nReturn an HTTP status 412 (PRECONDITION FAILED) with the\npatch-set ref that was a precondition for the apply-object\nof the /meta ref to be executed.\n\nChange-Id: I607cc62af96dc2aae3972673ebd94f4a7fee603d\n",
