Laravel 5, unprocessable entity 422 error - php

Question

I am trying to validate the login form and display errors on the page. But i am getting a 422 error when i click on login.
Any help would be appreciated.
This is my handleLogin function that handles the processes when login button is clicked.
public function handleLogin(Request $request){
/* validate user */
$this->validate($request, User::$login_validation_rules);
$data = $request->only('email', 'password');
if(\Auth::attempt($data)){
return redirect()->route('home');
}
return back()->withInput();
}
The following is the routes.php
Route::get('/login', ['as' => 'login', 'uses' => 'LoginController#login']);
Route::post('/handleLogin', ['as' => 'handleLogin', 'uses' => 'LoginController#handleLogin']);
Route::get('/home', ['as' => 'home', 'uses' => 'UsersController#home']);
Route::get('/logout', ['as' => 'logout', 'uses' => 'LoginController#logout']);
Route::resource('users', 'UsersController', ['only' => ['create', 'store']]);
And the following is the login form.
#extends('master')
#section('content')
<h2> Login </h2>
#if(count($errors))
<div class="alert alert-danger">
<ul>
#foreach($errors->all() as $error)
<li>{{ $error }}</li>
#endforeach
</ul>
</div>
#endif
{!! Form::open(array('route' => 'handleLogin')) !!}
<div class="form-group">
{!! Form::label('email') !!}
{!! Form::text('email', null, array('class' => 'form-control')) !!}
</div>
<div class="form-group">
{!! Form::label('password') !!}
{!! Form::password('password', array('class' => 'form-control')) !!}
</div>
{!! Form::token() !!}
{!! Form::submit('Login', array('class' => 'btn btn-default')) !!}
{!! Form::close() !!}
#stop
