my code below results in a page not found when I browse to the path. How can I debug what is going wrong? I dont see any errors and I have cleared the cache.

  path: '/admin/viewfiles'
    _controller: '\Drupal\mymodule\Controller\FileView::content'
    _title: 'File Operations Module Description'
    _permission: 'access administration pages'
  • See Adding a basic controller. Did you create the src/Controller folders? Did you name your controller file FileView.php? Does your controller extend the ControllerBase class? Did you namespace your controller? – No Sssweat May 11 '17 at 21:51
  • Yes yes and yes . I did all that . If not I would get an error when running drush – Diana May 11 '17 at 23:29
  • So far everything looks good, @Diana can you post your controller's code? – No Sssweat May 11 '17 at 23:36

    Is the routing file named correctly? – Kevin May 11 '17 at 23:50
  • Remove the initial backslash from the controller namespace + make sure the module is neabled + make sure you have cleared cache after making changes in routing file. – user21641 May 12 '17 at 6:57
