# `next-head-count` is missing
#### Why This Error Occurred
You have a custom `pages/_document.js` that doesn't have the components required for Next.js to render correctly.
#### Possible Ways to Fix It
Ensure that your `_document.js` is importing and rendering all of the [required components](https://nextjs.org/docs/advanced-features/custom-document).
In this case you are most likely not rendering the `<Head>` component imported from `next/document`.
