title: 'next-head-count is missing'
Why This Error Occurred

Possible Ways to Fix It
Ensure that your _document.js is importing and rendering all of the required components.
In this case you are most likely not rendering the <Head> component imported from next/document.
Rendered from the public repository vercel/next.js on GitHub; content belongs to its authors. Cached for up to an hour.
