   cursor: {
      id: Long("0"),
      ns: "test.$cmd.aggregate",
      firstBatch: [
         {
            type: "MissingRoutingTable",
            description: "There is a sharded collection without routing table",
            details: {
               namespace: "test.authors",
               collectionUUID: new UUID("1ad56770-61e2-48e9-83c6-8ecefe73cfc4")
            }
         }
      ],
   },
