# No Script in Document

> Prevent usage of `next/script` in `pages/_document.js`.

> ⚠️ This error is not relevant in Next.js versions 12.1.6 or later. Please refer to the updated [error message](https://nextjs.org/docs/messages/no-before-interactive-script-outside-document).

#### Why This Error Occurred

You should not use the `next/script` component in `pages/_document.js` in Next.js versions prior to 12.1.6. That's because the `pages/_document.js` page only runs on the server and `next/script` has client-side functionality to ensure loading order.

#### Possible Ways to Fix It

If you want a global script, use `next/script` in `pages/_app.js` instead.

```jsx
import Script from 'next/script'

function MyApp({ Component, pageProps }) {
  return (
    <>
      <Script src="/my-script.js" />
      <Component {...pageProps} />
    </>
  )
}

export default MyApp
```
