      ns: "test.$cmd.aggregate",
      firstBatch: [
         {
            type: "AuthoritativeShardCatalogCollectionsPresent",
            description: "Found authoritative shard catalog collections on a shard that is fully downgraded",
            details: {
               namespace: "config.shard.catalog.chunks",
               shard: "shard-rs0"
            }
         }
      ],
   },
