Firebase Google Auth在ReactJS

Question

我正在尝试在React + Firebase应用中实施Google登录。当我使用signInWithPopup()方法时，一切都很顺利。但是，当我使用signInWithRedirect() - 我的首选方法 - 身份验证仍然有效，但我在控制台中遇到了这些恼人的错误：

Uncaught TypeError: Cannot read property 'appendChild' of null
    at foundation-chrome-content.js:3

Error in event handler for extension.onRequest: TypeError: Cannot read property 'removeEventListener' of null
    at bindShortcuts (chrome-extension://nlipoenfbbikpbjkfpfillcgkoblgpmj/javascripts/content_script.js:1:9424)
    at chrome-extension://nlipoenfbbikpbjkfpfillcgkoblgpmj/javascripts/content_script.js:1:13864

这是我处理App.js身份验证的代码：

componentDidMount() {
  firebase.auth().onAuthStateChanged(user => this.setState({ user }));
  firebase.auth().getRedirectResult().then(result => {
    var user = result.user;
    this.setState({ user });
  }).catch(error => {
    if (error.code === 'auth/account-exists-with-different-credential') {
      alert('You have already signed up with a different auth provider for that email.');
    } else {
      console.error(error);
    }
  });
}

toggleSignIn = () => {
  if (this.state.user) {
    firebase.auth().signOut();
  } else {
    var provider = new firebase.auth.GoogleAuthProvider();
    firebase.auth().signInWithRedirect(provider);
  }
}

我很感激任何见解和帮助。
