How to ssh to amazon centos via ssh-node

Stupid question, trying to connect to my amazon centos instance using node-ssh

at terminal connecting: ssh -i myCert.pem centos@10.10.10.10

let fs = require('fs')
let path = require('path');
const node_ssh = require('node-ssh');
const ssh = new node_ssh();

ssh.connect({
  host: 'http://10.10.10.10',
  username: 'centos',
  privateKey: myCert.pem
}).then(resp => {
  console.log(resp);
  ssh.dispose();
});

Here getting an error:
