                          I want to enable the features of my Mongodb 3.4 after upgrading. I have sharded cluster enviroment And after I ran the commands:

    use admin
    db.adminCommand ({setFeatureCompatibilityVersion: "3.4"})

In mongos instance I got the following output:

> {"ok": 1}

But when I try to check with it succeeded with command:

    db.adminCommand ({getParameter: 1, featureCompatibilityVersion: 1})

I get the following output:

> {"ok": 0, "errmsg": "no option found to get"}

And when I check in ops manager I see that the command did not work
