title: '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.
