Error while doing signup

[vasa-develop]

version

0.0.5

Expected Behaviour

I ran the below code:

var Keybase = require('node-keybase')
let keybase = new Keybase('lollerblades', 'keep it secret keep it safe')

keybase.signup({
  name: "Lol",
  username: "lollerblades",
  email: "[email protected]",
  passphrase: "keep it secret keep it safe",
  invitation_id: "342128cecb14dbe6af0fab0d"
}, function(err, result) {})

Actual Behaviour

The following error was thrown:

buffer.js:207
    throw new ERR_INVALID_ARG_TYPE(
    ^
