title: 'Invalid `webpack` resolve alias'
|
|
---
|
|
|
|
## Why This Error Occurred
|
|
|
|
When overriding `config.resolve.alias` incorrectly in `next.config.js` webpack will throw an error because private-next-pages is not defined.
|
|
|
|
## Possible Ways to Fix It
|
|
|
|
This is not a bug in Next.js, it's related to the user adding a custom webpack(config) config to next.config.js and overriding internals by not applying Next.js' aliases. Solution would be:
|
|
|
|
```js filename="next.config.js"
|
|
webpack(config) {
|
|
config.resolve.alias = {
|
|
...config.resolve.alias,
|
|
// your aliases
|
|
}
|
|
}
|
|
```
