## Description [Invalid Page / API Route Config](https://nextjs.org/docs/messages/invalid-page-config) shows some examples. However, runtime examples are same `nodejs` runtime. Then I add `edge` value instead of duplicate value. ### Improving Documentation - [x] Run `pnpm prettier-fix` to fix formatting issues before opening the PR. - [x] Read the Docs Contribution Guide to ensure your contribution follows the docs guidelines: https://nextjs.org/docs/community/contribution-guide Co-authored-by: Delba de Oliveira <[email protected]>

title: Invalid Page / API Route Config
|
|
---
|
|
|
|
## Why This Error Occurred
|
|
|
|
In one of your pages or API Routes, you used `export const config` with an invalid value.
|
|
|
|
## Possible Ways to Fix It
|
|
|
|
- The page's `config` must be an object initialized directly when being exported and not modified dynamically.
|
|
- The `config` object must only contain static constant literals without expressions.
