The method returns a cursor with a batch of documents showing the inconsistencies found in the sharding metadata. The example below shows a cursor with a ShardCatalogCacheCollectionMetadataMismatch inconsistency document:

{
   cursor: {
      id: Long("0"),
      ns: "test.$cmd.aggregate",
      firstBatch: [
         {
            type: "ShardCatalogCacheCollectionMetadataMismatch",
            description: "Shard is missing metadata or routing information for the collection",
            details: {
               namespace: "testdb.testcollection",
               collectionUUID: new UUID("6dc337aa-4c0f-4f98-bc3a-bdfb516fbf51"),
               details: []
            }
         }
      ],
   },
   ok: 1
