UnhandledPromiseRejectionWarning: Error: invalid command ping www.google.com

[asdutoit]

I am attempting to connect to one of my network switches via ssh and just run the command ping www.google.com but get the following error:

node index.js
Ping Completed
(node:56662) UnhandledPromiseRejectionWarning: Error: invalid command www.google.com.
...

My config:

ssh
  .connect({
    host: "172.35.0.2",
    username: "admin",
    port: 22,
    password,
    // debug: console.log,
    algorithms: {
      kex: [

        "diffie-hellman-group-exchange-sha256",

      serverHostKey: [

        "ecdsa-sha2-nistp521",
      ],
      hmac: ["hmac-sha2-256", "hmac-sha2-512", "hmac-sha1"],
    },
  })
  .then(() => {
    ssh
      .execCommand("ping www.google.com", { options: { pty: true } })
      .then((result) => {
        console.log("STDOUT: " + result.stdout);
        console.log("STDERR: " + result.stderr);
      });
  })
  .then(
    function () {
      console.log("Ping Completed");
    },
    function (error) {
      console.log("Something's wrong");
      console.log(error);
    }
  );

What am I doing wrong?

I am able to manually connect to the switch and run ping successfully:
