Как подключиться по ssh к экземпляру EC2 через хост-бастион в nodejs

Question

Я пробовал код ниже и использовал node-ssh-forward Пакет NPM.

const SSHConnection = require('node-ssh-forward').SSHConnection

    var run = async () => {
        const ssh = new SSHConnection({
            username: 'Testuser', 
            endHost: 'example.com',
            bastionHost: 'bastion01.aws.cloud',
            privateKey: 'C:/Users/user/.ssh/id_rsa'
          })
         await ssh.executeCommand('uptime')
    }
    run()
