title: Cannot GET /implicit/callback
body: <p>I am integrating okta in my react application for SSO, I followed steps mentioned in okta developer's guide</p>
  
  <p>Here is my index.js</p>
  
  <pre><code>import React, { Component } from 'react';
  import { BrowserRouter as Router, Route } from 'react-router-dom';
  import { Security, ImplicitCallback } from '@okta/okta-react';
  import HomePage from './components/home/HomePage';
  import ReactDOM from 'react-dom';
  
  const config = {
    issuer: 'https://XXX.oktapreview.com',
    redirect_uri: window.location.origin + '/implicit/callback',
    client_id: '0oxxxxxxxxxxxxx7'
  }
  
  class App extends Component {
    render() {
      return (
        &lt;Router&gt;
          &lt;Security issuer={config.issuer}
                    client_id={config.client_id}
                    redirect_uri={config.redirect_uri}
          &gt;
            &lt;Route path='/' exact={true} component={HomePage}/&gt;
            &lt;Route path='/implicit/callback' component={ImplicitCallback}/&gt;
          &lt;/Security&gt;
        &lt;/Router&gt;
      );
    }
  }
  
  ReactDOM.render(&lt;App/&gt;, document.getElementById('app'));
  </code></pre>
  
  <p>constantly getting Cannot GET /implicit/callback.
  My app configuration in okta is like below:

  <p>I am guessing something wrong with webpack config.</p>
