NextJS Tips Series: Custom 500 error page

The 500 errors are handled both client-side and server-side by the Error component.

If you wish to override it, define the file pages/_error.js and add the following code.

// pages/_error.js
function Error({ statusCode }) {
return (
<p>
{statusCode
? `An error ${statusCode} occurred on server`
: 'An error occurred on client'}
</p>
)
