      I tried to run setIndexCommitQuorum against a mongos on a non-existent index build and the command returns successfully:

      {
       "ok" : 1,
       "$clusterTime" : {
               "clusterTime" : Timestamp(1620827363, 2),
               "signature" : {
                       "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
                       "keyId" : NumberLong(0)
               }
       },
       "operationTime" : Timestamp(1620827363, 2)
}

      Running the same command against the primary mongod returns the expected result:

      {
       "ok" : 0,
       "errmsg" : "Cannot find an index build on collection 'repro.repro' with the provided index names",
       "code" : 27,
       "codeName" : "IndexNotFound",
       "$gleStats" : {
               "lastOpTime" : {
                       "ts" : Timestamp(1620827362, 16),
                       "t" : NumberLong(1)
               },
               "electionId" : ObjectId("7fffffff0000000000000001")
       },
       "lastCommittedOpTime" : Timestamp(1620827363, 2),
       "$configServerState" : {
               "opTime" : {
                       "ts" : Timestamp(1620827362, 22),
                       "t" : NumberLong(-1)
               }
       },
       "$clusterTime" : {
               "clusterTime" : Timestamp(1620827363, 2),
               "signature" : {
                       "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
                       "keyId" : NumberLong(0)
               }
       },
       "operationTime" : Timestamp(1620827363, 2)
}
