      1. Create a sharded cluster
      2. Create a time-series collection
      3. Connect to the mongos
      4. On the time-series collection, run the following command: db.runCommand({ collStats: "timeseries"})

      Running db.runCommand({ collStats: "timeseries"}) on a mongos for a time-series collection results in the following error: 

      {
	"ok" : 0,
	"errmsg" : "expected  to have a numeric type, but it is a missing",
	"code" : 13118,
	"codeName" : "Location13118",
	"$clusterTime" : {
		"clusterTime" : Timestamp(1621607006, 1),
		"signature" : {
			"hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
			"keyId" : NumberLong(0)
		}
	},
	"operationTime" : Timestamp(1621607002, 1)
}

      The InTel team depends on this command for Data Explorer to work properly so it is important that this behavior is uniform across deployment types.
