Reflection Exception

Laravel 5.2, all my modules are working, yet I am getting this trouble in one of my module. I'm using Laravel 5.2 and Pingpong modules v2.2.0

ReflectionException in Route.php line 280:
Class Modules\Records\Http\Controllers\RecordsController does not exist```

This is my routes.php of Records module..

<?php

Route::group(['middleware' => 'auth', 'prefix' => 'records', 'namespace' => 'Modules\Records\Http\Controllers'], function()
{
    Route::get('/', [
                    'as'=>'records',
                    'uses'=>'RecordsController@index']);

    Route::get('addInstitution', [
                    'as'=>'records.add_admin_institutions',
                    'uses'=>'RecordsController@addInstitution']);

    Route::get('addUniversity', [
                    'as'=>'records.add_university',
                    'uses'=>'RecordsController@addUniversity']);

    Route::post('addUniversity/submit', [
                    'as'=>'records.addUniversitySubmit',
                    'uses'=>'RecordsController@addUniversitySubmit']);

});
