      I attempted to execute the following against a sharded cluster:

      (byebug) client.use(:admin).command(getParameter: 1, featureCompatibilityVersion: 1)
      *** Mongo::Error::OperationFailure Exception: no option found to get ()

      Shell version:

      mongos> db.adminCommand( { getParameter: 1, featureCompatibilityVersion: 1 } )
      	"ok" : 0,
      	"errmsg" : "no option found to get",
      	"operationTime" : Timestamp(1547668183, 1),
      	"$clusterTime" : {
      		"clusterTime" : Timestamp(1547668183, 1),
      		"signature" : {
      			"hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
      			"keyId" : NumberLong(0)

      The phrase "no option found to get" is confusing for the following reasons:

      1. I requested to get a parameter, the error message talks about an option.
      2. "no option" seems to imply that I requested several, whereas I requested only one.
      3. Can I insert an option like I insert data, so that later this option would be "found"?

      A more clear message to me would be something like the following:

      • Unrecognized parameter "featureCompatibilityVersion"
      • Unknown parameter "featureCompatibilityVersion"

      A better yet message would say something like:

      • Parameter "featureCompatibilityVersion" is not supported for mongos

      Also, this error message came without a numeric code.
