Hello @Expo team

I am integrating firebase to my react-native project but while integrating it shows the following error

Here is the App.js code

import React, { Component } from 'react';
import { StyleSheet, Text, View } from 'react-native';
import {createStackNavigator, createSwitchNavigator } from 'react-navigation';
import Home from './components/Home';
import Login from './components/Login';

import AuthLoading from './components/AuthLoading';
import PedometerSensor from './components/PedometerSensor';
import ViewStepCount from './components/ViewStepCount';
import Splash from './components/Splash';

const firebase = require("firebase");
// Required for side-effects
require("firebase/firestore");

const AppStack = createStackNavigator({ Home: Home, PedometerSensor: PedometerSensor, ViewStepCount: ViewStepCount });
const AuthStack = createStackNavigator({ Login: Login });

class App extends Component{
 componentWillMount() {
    const config = {
      apiKey: "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
      authDomain: "firestorecrud-b08be.firebaseapp.com",
      databaseURL: "https://firestorecrud-b08be.firebaseio.com",
      projectId: "firestorecrud-b08be",
      storageBucket: "firestorecrud-b08be.appspot.com",
      messagingSenderId: "742054197796"
 };
 firebase.initializeApp(firebaseconfig);
  }
}

export default createSwitchNavigator(
  {
    AuthLoading: AuthLoading,
    App: AppStack,
    Auth: AuthStack,
  },
  {
    initialRouteName: 'AuthLoading',
  }
);

Can anyone please help me out what is the issue while configuring firebase?

Thank you in advance

Hi! This seems like it’s probably an issue with your firebase configuration either in your code or on the server.
