How to obtain the Vault Server status with the response code back from Vault Server?

[rav94]

Is there a specific way to obtain the server status with the response code from Vault Server in node-vault-js? I tried [https://github.com/kr1sp1n/node-vault/blob/master/example/status.js](original example) as follows by using this library,

vault.status(function(err, result) {
    if (err) {
      throw err
    }
    console.log('Read with response: ', result)
    });

But it doesn't work, is this implemented?
