# getInitialProps was defined as an instance method
#### Why This Error Occurred
`getInitialProps` must be a static method in order to be called by next.js.
#### Possible Ways to Fix It
Use the static keyword.
```js
export default class YourEntryComponent extends React.Component {
static getInitialProps() {
return {}
}
render() {
return 'foo'
}
}
```
or
```js
const YourEntryComponent = function () {
return 'foo'
}
YourEntryComponent.getInitialProps = () => {
return {}
}
export default YourEntryComponent
```
