Custom 404 page not picked up?

When you go to /404, then 404.js page is rendered. When you go to /doesnotexist, then the standard Next.js 404 page is rendered.

I'm not sure what else I'm supposed to do. The documentation (https://nextjs.org/docs/advanced-features/custom-error-page#404-page) says to create pages/404.js which is what I did.

Works perfectly in the codesandbox example that you're giving 🤔

Weird. If you start with the next.js hello world template on CSB, add a 404 page, you can reproduce the behaviour I've observed. Perhaps it works in my example because I restarted the CSB container…
