Uncaught Type Error: chat.setUser is not a function

[ninjatron]

I am trying to make firechat work with React for a web app. I used NPM to install firechat and followed along the documentation, however I am stuck. This is how I am trying to make it work:

`import FirechatUI from "firechat";
import Firechat from "firechat";

class ProfilePage extends Component {
constructor() {
super();
this.state = {
signed_in: false
};
}

componentWillMount() {
var signed_in = AuthStore.getSignInState();
this.setState({signed_in: signed_in});
var user = firebase.auth().currentUser;
if (user) {
// Get a Firebase Database ref
var chatRef = firebase.database().ref();
// Create a Firechat instance
var chat = new FirechatUI(chatRef, this.refs.firechatroom);
// Set the Firechat user
chat.setUser(user.uid, user.displayName);
}
}

render() {
let content = null;
if (this.state.signed_in) {
content =

This is the ProfilePage

`

Everything firechat related is above. And this is the console error I got:

This is the warning if I try to access to Profile Page (where firechat code is), moreover, I won't be able to open this page because of the error on ReactReconciler.js error on line 63.

I don't know a ton about React or Firechat, so I'd really appreciate help. What could I be doing wrong? I don't see why it would say chat.setUser is not a function, I am pretty sure I create the FirechatUI instance correctly. Also, I tried to create the instance using Firechat only (not FirechatUI) and still had to same error.

Thanks.
