Error in App.js file. As 'login' and 'actions' are imported & It has not used.

I am using React-Redux starter kit & trying to implement only Login Authentication.
In the App page: I am getting error. 'login' defined but never used & same error for 'loginUser' action.

Even I am getting error:
Uncaught TypeError: Cannot read property 'isAuthenticated' of undefined

This is my code:

import React, { Component, PropTypes } from 'react'
import { connect } from 'react-redux'
import Navbar from './Navbar'
import Login from './Login'
import { loginUser } from './redux/module/action'

class App extends Component {
render () {
const { dispatch, isAuthenticated, errorMessage } = this.props
return (

)
}
}

App.propTypes = {
dispatch: PropTypes.func.isRequired,
isAuthenticated: PropTypes.bool.isRequired,
errorMessage: PropTypes.string
}

function mapStateToProps (state) {
const{ auth } = state
const { isAuthenticated, errorMessage } = auth

return {
isAuthenticated,
errorMessage
}
}

export default connect(mapStateToProps)(App)
