Error "The requested URL could not be matched by routing" using ZF2

I'm using apigility (ZF2). The following error occurs when sending a request: The requested URL could not be matched by routing. The error occurs when I try to get a get request through the link: http://0.0.0.0:8888/leads using the postman (chrome plugin).

The error is supposed to refer to some route error. However, you can not see this error yet.

The directory structure follows below:

The code for my chat / module.php file is as follows:

<?php
   namespace chat;

   use chat\V1\Rest\Leads\LeadsEntity;
   use chat\V1\Rest\Leads\LeadsMapper;
   use Zend\Db\ResultSet\ResultSet;
   use Zend\Db\TableGateway\TableGateway;

   use ZF\Apigility\Provider\ApigilityProviderInterface;

 class Module implements ApigilityProviderInterface
 {
   public function getConfig()
   {



      return array(
        'factories' => array(
            'chatLeadsTableGateway' =>  function($sm) {
                $dbAdapter = $sm->get('Adaptador');
                $resultSetPrototype = new ResultSet();
                $resultSetPrototype->setArrayObjectPrototype(new LeadsEntity());
                return new TableGateway('nomedatable', $dbAdapter, null, $resultSetPrototype);
            },
            'chat\V1\Rest\Leads\LeadsMapper' => function($sm) {
                $tableGateway = $sm->get('chatLeadsTableGateway');
                return new LeadsMapper($tableGateway);
            }
        ),
     );

   }

   public function getAutoloaderConfig()
   {
    return array(

                __NAMESPACE__ => __DIR__,
            ),
        ),
    );
  }
 }

The code for the chat / module.config.php file is as follows:

                ),
            ),
