TypeError: Cannot read property 'namespacesRequired' of undefined

I got this error after update the package to version 0.20.0

TypeError: Cannot read property 'namespacesRequired' of undefined
    at Function._callee$ (xxx\node_modules\next-i18next\dist\hocs\app-with-translation.js:169:69)

After investigated. I found that the error occur when I add getInitialProps in _app.jsx like below.

class MyApp extends App {
  static async getInitialProps({ ctx }) {
    return {}
  }

  render () {
    const { Component, pageProps } = this.props
    return (
      <Container>
        <Component {...pageProps} />
      </Container>
    )
  }
}

export default appWithTranslation(MyApp)

Got a similar issue, I’m using other HOC like “withRedux” and “withRedux” saga, My problem was fixed by moving “appWithTranslation” to the first level :

export default withRedux(makeStore)(withReduxSaga(appWithTranslation(MyApp)))

I don’t know if my problem is same at this. But I faced the same error in server side when production build though it don’t reproduce in development server. My version of this library is 0.31.0
