Custom /_error without /404

Why This Error Occurred

You added a custom /_error page without adding a custom /404 page. Adding a custom /_error typically opts your application out of having the automatic static optimization applied to the 404 page.

Possible Ways to Fix It

Add a pages/404.js with the 404 page you would like to show.
