Only thing that catches my eye is in the composer.json I don't see.

"app/models",

Witch would make sense because no matter how many times you composer dump-autoload you don't have it were composer can even see the models directory.

@dragonfire1119 thanks for your reply. I actually removed app/models directory. I put my controllers, models (which I now called entities) in apps/src/IAPON/ directory where I also namespaced them. I did put back app/models as you suggested but I'm still getting the same Exception error.

Found the solution. It has something to do with efficiently/authority package.

UsersController.php

Before:

class UsersController extends BaseController {
  public function __construct()
  {
  	$this->loadAndAuthorizeResource();
  }
// rest of the code...

Solution:

class UsersController extends BaseController {
  public function __construct()
  {
  	$this->loadAndAuthorizeResource(['class' => "IAPON\\Entities\\User"]);
  }
// rest of the code...

If the model class is namespaced differently than the controller you will need to specify the class option.

Glad that you found the problem I had a feeling that it was something with the package because I've never used it. I didn't realize that you moved the controllers ETC.. else where.
