Apigility Error after installation and creation of first service of demo - zend-framework2

Question

i have just installed Apigility and following the tutorials i have an error. When i try with Postman to call my service i get an error like this
Zend\View\Renderer\PhpRenderer::render: Unable to render template "status/v1/rpc/ping/ping/ping"; resolver could not resolve to a file
My call on postman is like this.
http://localhost/demo/api/public/ping
How to solve this problem?

Answer 1

Apigility as part of Zend Framework is now part of the open source Laminas project and is called Laminas API Tools.
Make sure that Zend OPcache is disabled in your PHP configuration before trying to create your API service.
Quick steps to verify:
create a phpconfig.php file that displays php configuration for your development server. Do not put this in production. See for details https://www.php.net/manual/en/function.phpinfo.php
open this file on your server http://localhost:8080/phpconfig.php and look for two things a) ZendOPcache - if it is enabled, then look at b) loaded php.ini something like /etc/php7/cli/php.ini
add opcache.enable=0 to the [opcache] section. Even if it is commented out, it is still loaded, you saw it above right?
restart your PHP server / application to verify that Zend OPcache is off and that's it.

For anyone have this problem, in the example of Apigility change the example code from this:
namespace Status\V1\Rpc\Ping;
use Zend\Mvc\Controller\AbstractActionController;
use ZF\ContentNegotiation\ViewModel;
class PingController extends AbstractActionController
{
public function pingAction()
{
return new ViewModel([
'ack' => time()
]);
}
}
to this
namespace Status\V1\Rpc\Ping;
use Zend\Mvc\Controller\AbstractActionController;
class PingController extends AbstractActionController
{
public function pingAction()
{
return ['ack' => time()];
}
}
Doing this the example is fine.
