How can I show the custom error page with Vercel 'Serverless Function timed out' error?

[mitestainer]

Summary

I can make the custom error pages work for every server-side error except that one from Vercel when the serverless function timed out. Is there a way to make the custom Next.js error page appear when that error happens?

I've set up a simple example where the home page has a time-out inside getServerSideProps, as well as the _error.js and 500.js pages (left both of them as .js for the sake of simplicity). Obviously, I can't reproduce the error locally, but I can't also make the page appear on the deployed version. 🙁
