Describe the bug

How to reproduce the bug?

1. Clone repo above

2. npm i

3. npm run dev you'll see that the grapes iframe and boilerplate is rendered into the canvas.

4. Try to export and you'll see that all the grapes boilerplate is also rendering into the canvas

5. Open dev tools and you'll see the error:

Component.ts:910 Uncaught (in promise) TypeError: Cannot read properties of null (reading 'querySelector')
    at o2.getBody (Component.ts:910:16)
    at o4._upFrame (sample.js:20:20)

    at g (backbone.js:482:10)

Additional context

What is the expected behavior? The editor should render it's boilerplate properly, the same way as it

What is the current behavior? The parser doesn't seem to work. The editor renders the iframe that's meant to encapsulate the editor DOM. It also exports all the grapesJS boilerplate.
