# Missing webpack config
|
|
|
|
#### Why This Error Occurred
|
|
|
|
The value returned from the custom `webpack` function in your `next.config.js` was undefined. This can occur from the initial config value not being returned.
|
|
|
|
#### Possible Ways to Fix It
|
|
|
|
Make sure to return the `webpack` config from your custom `webpack` function in your `next.config.js`
|
|
|
|
```js
|
|
// next.config.js
|
|
|
|
module.exports = {
|
|
webpack: (config, { buildId, dev, isServer, defaultLoaders, webpack }) => {
|
|
// Note: we provide webpack above so you should not `require` it
|
|
// Perform customizations to webpack config
|
|
config.plugins.push(new webpack.IgnorePlugin(/\/__tests__\//))
|
|
|
|
// Important: return the modified config
|
|
return config
|
|
},
|
|
}
|
|
```
