Bug: Following getting-started instructions results in 11ty error

[Michael Potter]

Details

I followed the instructions found on the getting-started page found here https://wip-rocket.netlify.app/guides/first-pages/getting-started/

When I run npm start I receive the following error:

   npm run start

> rocket-test@1.0.0 start /Users/michael/Projects/rocket-test
> node --trace-warnings ./node_modules/.bin/rocket start

(node:69410) UnhandledPromiseRejectionWarning: TypeError [ERR_INVALID_ARG_TYPE]: The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received an instance of Object

Troubleshooting

It looks like 11ty is expecting a string by the time it gets to this function:

node_modules/@11ty/eleventy/node_modules/fs-extra/lib/output/index.js:18:27

However, it is getting an object. Here is an example of the data object going into fs.write() function:

err {
  file: '_site-dev/index.html',
  data: {
    stories: [],
    jsCode: '',
    html: '<h1 id="welcome-to-your-rocket-site"><a aria-hidden="true" href="#welcome-to-your-rocket-site"><span class="icon icon-link"></span></a>Welcome to your Rocket site</h1>\n' +
      '<p>Text here, like any markdown file.</p>'
  },
  encoding: 'utf8',
  callback: [Function (anonymous)]
}

hey,
thank you for trying an alpha package 🤗

yeah the docs site got a little ahead of what was published 🙈

it should work fine now 👍

PS: if you still find it not working please reopen or create a new issue 🤗
PPS: fair warning we will move this repo and publish via the official @rocket namespace soonish
