React Native Navigation - bottom tabs and drawer

I'm trying to add bottom tab bar in my jhipster ignite application, which uses react-native-navigation v2.

Screens are registered like:

Navigation.registerComponentWithRedux(LAUNCH_SCREEN, () => LaunchScreen, Provider, store)

Where e.g.:

export const LAUNCH_SCREEN = 'nav.LaunchScreen'

And here is the complete navigation:

export const topBar = {
  title: {
    text: 'MDNGHT',
    color: Colors.snow
  },
  leftButtons: [
    {
      id: 'menuButton',
      icon: Images.menuIcon,
      testID: 'menuButton',
      color: Colors.snow
    }
  ]
}

export const launchScreenComponent = {
  component: {
    id: 'id.launch',
    name: LAUNCH_SCREEN,
    options: {
      topBar: topBar,
      bottomTab: {
        fontSize: 12,
        text: 'HOME'
      }
    }
  }}

export const eventsScreenComponent = {
  component: {
    id: 'id.events',
    name: EVENTS_SCREEN,
    options: {
      topBar: topBar,
      bottomTab: {
        fontSize: 12,
        text: 'EVENTS'
      }
    }
  }
}

export const bottomTabs = {
  id: 'bottomTabs',
  children: [
    {
      stack: {
        children: [
          launchScreenComponent
        ]
      }
    },
    {
      stack: {
        children: [
          eventsScreenComponent
        ]
      }
    }
  ],
  options: {
    bottomTabs: {
      activeTintColor: 'red',
      inactiveTintColor: 'grey',
      backgroundColor: '#121212',
      borderTopWidth: 0,
      shadowOffset: {width: 5, height: 3},
      shadowColor: 'black',
      shadowOpacity: 0.5,
      elevation: 5
    }
  }
}

export const appStack = {
  root: {
    sideMenu: {
      left: {
        component: {
          name: DRAWER_CONTENT
        }
      },
      center: {
        bottomTabs: bottomTabs
      }
    }
  }
}

Navigation.events().registerAppLaunchedListener(() => {
    Navigation.setDefaultOptions({
      topBar: {
        topBar: {
          title: {
            color: Colors.snow
          }
        },
        backButton: {
          showTitle: false,
          testID: 'backButton',
          icon: Images.chevronLeftIcon,
          color: Colors.snow,
          iconColor: Colors.snow
        },
        background: {
          color: Colors.background
        }
      },
      sideMenu: {
        left: {
          enabled: false
        }
      }
    })

    Navigation.setRoot(appStack)

    // handle app state and deep links
    AppState.addEventListener('change', handleAppStateChange)
    Linking.addEventListener('url', handleOpenURL)
  })

I don't get any error message, my application just stops after start. When I put:

stack: {
          id: 'center',
          children: [launchScreenComponent]
        }

Instead of bottomTabs: bottomTabs in appStack, the application works (but without bottom tab bar)

It actually turns out that it is required to set an icon for each bottom tab, otherwise the app crashes:

  bottomTab: {
    fontSize: 12,
    text: 'HOME'
    icon: require('../shared/images/logo.png')
  }

This resolves the issue.
