# Custom Routes must return an array
#### Why This Error Occurred
When defining custom routes an array wasn't returned from either `headers`, `rewrites`, or `redirects`.
#### Possible Ways to Fix It
Make sure to return an array that contains the routes.
**Before**
```js
// next.config.js
module.exports = {
async rewrites() {
return {
source: '/feedback',
destination: '/feedback/general',
}
},
}
```
**After**
```js
module.exports = {
async rewrites() {
return [
{
source: '/feedback',
destination: '/feedback/general',
},
]
},
}
```
