title: Laravel 7 - Why i can't using the same route in different group of routing?
body: <p>So i have this code in my route :</p>
  <pre><code>// Facilitator Priviledges
      Route::group(['roles'=&gt;'facilitator'],function(){
  
          //Material
          Route::get('/material', 'MaterialController@index');
          Route::post('/material', 'MaterialController@store');
          Route::get('/material/{course:id}/create', 'MaterialController@create');
          Route::get('/material/detail/{course:id}', 'MaterialController@show');
          Route::get('/material/{material:id}/edit', 'MaterialController@edit');
          Route::patch('/material/{material:id}', 'MaterialController@update');
          Route::delete('/material/{material:id}', 'MaterialController@destroy');
  
  
      });
  
      //Admin Priviledges
      Route::group(['roles'=&gt;'admin'],function(){
          Route::resource('/categories', 'CategoriesController');  
  
          //Material
          Route::get('/material', 'MaterialController@index');
          Route::post('/material', 'MaterialController@store');
          Route::get('/material/{course:id}/create', 'MaterialController@create');
          Route::get('/material/detail/{course:id}', 'MaterialController@show');
          Route::get('/material/{material:id}/edit', 'MaterialController@edit');
          Route::patch('/material/{material:id}', 'MaterialController@update');
          Route::delete('/material/{material:id}', 'MaterialController@destroy');
      });
  </code></pre>
  <p>It has the same route, in this case, <strong>Material</strong> Route that both admin and facilitator roles can access it, but when the code runs it can be only one role that working fine (I'm using admin) and the other giving error (503) Servive unavailable</p>
