TypeError: TypeError: undefined не является объектом (оценка 'this.props.lang.takeawayScreen.title')

Question

Я создаю приложение, используя реактивный и избыточный. я создал редуктор с именем LanguageReducer. js для смены языков в моем приложении. ниже его LanguageReducer. js:

import { english } from '../../assets/jsons/english';
import { romanian } from '../../assets/jsons/romanian';


const INITIAL_STATE = romanian;

export default (state = INITIAL_STATE, action) => {
 switch(action.type) {
  case 'language_data':
   return action.payload;
  default: 
   return state;
 }
}

их я создал languageaction. js вот так:

export const selectLanguage = (val) => {
    return{
        type: 'language_data',
        payload: val
    };
};

в моем реагирующем нативном компоненте я злюсь:

import React, { Component } from "react";
import { Text, View } from "react-native"; 
import { connect } from "react-redux";
const mapStateToProps = (state, ownProps) => ({
  lang: state.lang
});
const mapDispatchToProps = {
  // ... normally is an object full of action creators
};

class MyComponent extends Component {
  constructor(props){super(props)}
  render() {
    console.log(this.props.lang)
    return ( <Text>{this.props.lang.takeawayScreen.title}</Text>);
  }
}
export default connect(mapStateToProps, mapDispatchToProps)(MyComponent);

мой engli sh. js это так:

export const english = {
  welcomeScreen: {
    loginButton: "Login with email",
    loginFacebook: "Login with Facebook",
    welcomeText:"Get in love with your favorite food right now with our application!",
    continueBy: "Continue with ..."
  },
  homeScreen: {
    diningText: "View Restaurants",
    recomandedTitle: "Recommended Restaurants",
    recomandedDescription: " Recommended restaurants based on your searches"
  },
  takeawayScreen: {
    title: "Search for Takeaways",
    subtitle:" Fill all the required inputs and find restaurants in your location to get your loved food",
    destinationPlaceholder: "Search or get your current location",
    bookingDatePlaceholder: "Select date",
    timePlaceholder: "select hour",
    partySizePlaceholder: "number of guests",
    guestsword: "guests",
    dialogTitle: "Enter number of guests",
    dialogInputPlaceholder: "Number of guests",
    rangeWord: "Range",
    findButton: "FIND RESTAURANTS",
    pickerText: "Select the number of guests",
    guestsLabel1: "One Guest",
    guestsLabel2: "Two Guests",
    guestsLabel3: "Three Guests",
    guestsLabel4: "Four Guests",
    guestsLabel5: "Five Guests"
  },
  dineinScreen: {
    title: "Search for Dine In",
    subtitle:" Fill all the required inputs and find restaurants in your location to get your loved food",
    destinationPlaceholder: "Search or get your current location",
    bookingDatePlaceholder: "Select date",
    timePlaceholder: "select hour",
    partySizePlaceholder: "number of guests",
    guestsword: "guests",
    dialogTitle: "Enter number of guests",
    dialogInputPlaceholder: "Number of guests",
    rangeWord: "Range",
    findButton: "FIND RESTAURANTS",
    pickerText: "Select the number of guests",
    guestsLabel1: "One Guest",
    guestsLabel2: "Two Guests",
    guestsLabel3: "Three Guests",
    guestsLabel4: "Four Guests",
    guestsLabel5: "Five Guests"
  }
};

в моей консоли это показывает мне это объект, когда я вызываю console.log(this.props.lang):

"lang": Object {
    "homeScreen": Object {
      "diningText": "Vezi restaurante",
      "recomandedDescription": "Restaurante recomandate in functie de cautarile tale",
      "recomandedTitle": "Restaurante recomandate",
    },
    "welcomeScreen": Object {
      "continueBy": "Continuați prin ...",
      "loginButton": "Login cu email",
      "loginFacebook": "Login cu Facebook",
      "welcomeText": "Indragostiți-vă de mâncarea preferată chiar acum cu aplicația noastră!",
    },
  },

, когда я запускаю приложение, оно показывает мне эту ошибку: TypeError: TypeError: undefined не является объектом (оценка 'this.props.lang.takeawayScreen.title' ). Я не знаю, почему в консоли он не показывает полный объект языка, что я пропустил?
