# Missing Env Value
|
||
|
|
|
||
|
|
#### Why This Error Occurred
|
||
|
|
|
||
|
|
One of your pages' config requested an env value that wasn't populated.
|
||
|
|
|
||
|
|
```js
|
||
|
|
// pages/index.js
|
||
|
|
export const config = {
|
||
|
|
// this value isn't provided in `.env`
|
||
|
|
env: ['MISSING_KEY'],
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
```
|
||
|
|
// .env (notice no `MISSING_KEY` provided here)
|
||
|
|
NOTION_KEY='...'
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Possible Ways to Fix It
|
||
|
|
|
||
|
|
Either remove the requested env value from the page's config, populate it in your `.env` file, or manually populate it in your environment before running `next dev` or `next build`.
