arguments callee and caller cannot be accessed in strict mode

[gkrinc]

I get this error from my route reducer which is a copy of the provided redux example:

import { ActionConst } from 'react-native-router-flux';

const initialState = {
    scene: {
        sceneKey: null
    }
};

export default function route(state = initialState, action) {
    switch (action.type) {
        // focus action is dispatched when a new screen comes into focus
        case ActionConst.FOCUS:
            return {
                ...state,
                scene: action.scene
            };

        // ...other actions

        default:
            return state;
    }
}

If I remove the case ActionConst.FOCUS the error goes away, but I lose the ability to know which scene is current.

This is my router setup:

const RouterWithRedux = connect()(Router);

class MyApp extends React.Component {
...
  render() {
    return (
      <Provider store={store}>
        <AppDrawersContainer>
          <RouterWithRedux hideNavBar={true}>
            <Scene key="root" renderTitle={() => { return <AppLogo /> }}>
              <Scene key="launch" component={LaunchPage} title="Launch" initial={true}/>
              <Scene key="venues" component={VenuePage} title="Venues"/>
              <Scene key="home" component={HomePage} title="Home" />
            </Scene>
          </RouterWithRedux>
        </AppDrawersContainer>
      </Provider>
    );
  }
}

I'm don't have the createReducer prop on my router, cause I assume that's what this is taking care of:

const RouterWithRedux = connect()(Router);

If I remove redux-freeze the problem goes away...I assume something is mutating state when it shouldn't be.

This code from Actions.js seems to be what's causing the error:

focus(props = {}) {
  return this.callback({ ...filterParam(props), type: ActionConst.FOCUS });
}

Any help would be REALLY appreciated.
