Проверьте метод рендеринга PodCastScreen React Native

Я создаю приложение для плеера в React Native, и у меня появляется эта ошибка. Я никогда не видел этой ошибки. Я пробовал очистить кеш и проверить мой импорт и экспорт.

Первый набор кода взят из компонента PodCastScreen, а второй набор кода - из компонента Player.

Вот мой код:

import React, {Component} from 'react';
import {Button, Platform, StyleSheet, Text, View} from 'react-native';
import {createStackNavigator, createDrawerNavigator} from 'react-navigation';
import { Player } from './PodcastLayers/Player';

export const TRACKS = [
{
title: 'Stressed Out',
artist: 'Twenty One Pilots',
PodcastArtUrl: "http://36.media.tumblr.com/14e9a12cd4dca7a3c3c4fe178b607d27/tumblr_nlott6SmIh1ta3rfmo1_1280.jpg",
audioUrl: "http://russprince.com/hobbies/files/13%20Beethoven%20-%20Fur%20Elise.mp3",
},
{
title: 'Love Yourself',
artist: 'Justin Bieber',
PodcastArtUrl: "http://arrestedmotion.com/wp-content/uploads/2015/10/JB_Purpose-digital-deluxe-album-cover_lr.jpg",
audioUrl: 'http://oranslectio.files.wordpress.com/2013/12/39-15-mozart_-adagio-fugue-in-c-minor-k-546.mp3',
},
{
title: 'Hotline Bling',
artist: 'Drake',
PodcastArtUrl: 'https://upload.wikimedia.org/wikipedia/commons/c/c9/Drake_-_Hotline_Bling.png',
audioUrl: 'http://russprince.com/hobbies/files/13%20Beethoven%20-%20Fur%20Elise.mp3',
},
];
