undefined is not an object

After upgrading react-navigation to his latest version (2.18.0 => 3.0.2), I get the following error when navigating back from a tab router.

Have you tried updating this package to the latest version?

Yes, i'm using 2.0.8

I'm not able to repro this running react-navigation@3.0.2 and react-navigation-redux-helpers@2.0.8. Navigating back from a TabRouter should move you to the default route.

I can investigate further if you can provide an MCVE that reproduces the issue, in the form of an Expo Snack or a react-native init'd repo hosted on GitHub.

I think I may discover the reason. When I pass screenProps with some props (i.e. intl, etc..) the error is being triggered, but if I remove screenProps from the navigator, the navigation works as expected

// not working
const App = reduxifyNavigator(RootNavigator)
const mapStateToProps = ({ nav }) => ({
  state: nav,
  screenProps: {
    intl: {
      formatMessage: () => {},
    },
  },
})

export default connect(mapStateToProps)(App)

// working
const App = reduxifyNavigator(RootNavigator)
const mapStateToProps = ({ nav }) => ({
  state: nav,
})

export default connect(mapStateToProps)(App)

Does this issue occur if you're not using react-navigation-redux-helpers and instead just using react-navigation directly?

Again - if you'd like me to investigate I'll need an MCVE.
