# `notFound()`/`redirect()` inside a component rendered under `<Suspense>`

`lint/not-found-in-suspense` · severity **warn** · category Lint · detected by `void lint` and `void audit`

## Why it matters

Once streaming starts the HTTP status is already sent. `notFound()` thrown inside a Suspense boundary returns 200 with a noindex meta (a soft 404), and `redirect()` becomes a client-side redirect crawlers may not follow.

## How to fix it

Resolve existence at the top of `page.tsx` (or in `generateMetadata`) before rendering any `<Suspense>`, then pass the data down.

## Example

```tsx
export default async function Page({ params }) {
  const post = await getPost((await params).slug)
  if (!post) notFound()          // before any Suspense
  return <Suspense fallback={<Skeleton />}><Comments id={post.id} /></Suspense>
}
```
