Почему при запуске приложения на expo выводятся ошибки?

Я делаю приложение на react-native и expo. Не могу разобраться уже 3 часа. Я пишу expo start и когда я открываю приложение на своем устройстве, и оно начинает запускаться, но выводятся эти ошибки. Код из App.js

import React from 'react';
import ApolloProvider from 'react-apollo';
import ThemeProvider from 'styled-components';
import { Platform, StatusBar }  from 'react-native';

const _makeTheme = (type = 'light') => ({
    color: Colors,
    ...theme(type)
});
const dark = _makeTheme('dark');
const light = _makeTheme('light');

export default class App extends React.PureComponent {
    apolloClient = null;
    state = {
        isLoadingComplete: false,
        hasHydrated: false,
        theme: 'light'
    };

toggleTheme = () => {
    this.setState(
        ({ theme }) => ({
            theme: theme === 'light' ? 'dark' : 'light'
        }),
        this._changeStatusBarStyle
    );
};

_changeStatusBarStyle = () => {
    StatusBar.setBarStyle(
        this.state.theme === 'light' ? 'default' : 'light-content'
    );
};

componentDidMount() {
    return Platform.OS === 'ios' && this._changeStatusBarStyle();
}

render() {
    const { isLoadingComplete, hasHydrated } = this.state;

    if (!isLoadingComplete && !hasHydrated) {
        return ( <

                  <AppNavigator />
                </Bg>
              </ThemeProvider>
            </ThemeContext.Provider>
          </ApolloProvider>
        );
    }
}

_loadResourcesAsync = async() => {
    this.apolloClient = await setupApolloClient();

    return Promise.all([

        })
    ]);

    // reporting service, for example Sentry
    console.warn(error);
};

_handleFinishLoading = () => {
    this.setState({ isLoadingComplete: true, hasHydrated: true });
};
