# Error pages ## Errors handling When an error occurs on a page, the error is intercepted by an error route. The page is defined by `src/app/error.tsx` and it renders the component ``

You can define specific error pages by adding an `error.tsx` file to a nested route, for instance inside the folder `src/app/dashboard/` ## Not Found

If a page route doesn't exist, the Not Found page is rendered. Customize it by editing the file `src/app/not-found.tsx` {% hint style="info" %} Learn more about [Next.js Error Handling](https://nextjs.org/docs/app/building-your-application/routing/error-handling) {% endhint %}
