title: Cannot access `cookies()` or `headers()` in `"use cache"`
|
|
---
|
|
|
|
## Why This Error Occurred
|
|
|
|
A function is trying to read from the current incoming request inside the scope of a function annotated with `"use cache"`. This is not supported because it would make the cache invalidated by every request which is probably not what you intended.
|
|
|
|
## Possible Ways to Fix It
|
|
|
|
Instead of calling this inside the `"use cache"` function, move it outside the function and pass the value in as an argument. The specific value will now be part of the cache key through its arguments.
|
|
|
|
Before:
|
|
|
|
```jsx filename="app/page.js" highlight={5}
|
|
import { cookies } from 'next/headers'
|
|
|
|
async function getExampleData() {
|
|
"use cache"
|
|
const isLoggedIn = (await cookies()).has('token')
|
|
...
|
|
}
|
|
|
|
export default async function Page() {
|
|
const data = await getExampleData()
|
|
return ...
|
|
}
|
|
```
|
|
|
|
After:
|
|
|
|
```jsx filename="app/page.js" highlight={9}
|
|
import { cookies } from 'next/headers'
|
|
|
|
async function getExampleData(isLoggedIn) {
|
|
"use cache"
|
|
...
|
|
}
|
|
|
|
export default async function Page() {
|
|
const isLoggedIn = (await cookies()).has('token')
|
|
const data = await getExampleData(isLoggedIn)
|
|
return ...
|
|
}
|
|
```
