            if (! $this->defaultServiceManager->has($sm['service_manager']))

Please, provide more context on: where it happens (env) and how and to reproduce.
In general this is the application dependencies issue, not related to the app itself and can be solved by a proper installation.

[Coderyang666666]

url input localhost, error.log this fatal error appears, installFO.sh has been executed. ServiceListener.php is at
\home\yanghang\vendor\laminas\laminas-modulemanager\src\Listener\ServiceListener.php. Class ServiceListener's Constructor function is public function __construct(
/**
* Default service manager used to fulfill other SMs that need to be lazy loaded
*/
ServiceManager $defaultServiceManager,
$configuration = null
)
{
if ($configuration !== null)
{
$this->setDefaultServiceConfig($configuration);
}
}
$this->setDefaultServiceConfig($configuration);It doesn't seem to be being executed
The control flow is executed to
if (! $sm['service_manager'] instanceof ServiceManager)
{
xdebug_break();

            if (! $this->defaultServiceManager->has($sm['service_manager']))
            
            {
                // No plugin manager registered by that name; nothing to configure.
                continue;
            }

$this->defaultServiceManager- = null?
the Stack trace has ben already explicitly above.
I would have liked to debug, but I wouldn't debug with xdebug on apache2
The help is greatly appreciated

Like you said, I don't know which function calls the class ServiceListener

[Coderyang666666]

php's version is 8.1 at wsl

[ruslanbaidan]

The result php -v command shows already a lot of installation problems.
For example without pdo_msql the app can't work, but we are not advising on the system installations.
ServiceListener is the external Laminas (PHP framework used in Monarc) dependency and there is a problem of the project installation, but nothing to do the the application itself.

Thanks, I'll dig into that according this question

[Coderyang666666]

Why is it displayed like this， after http://localhost

[Coderyang666666]

Under the http://localhost page

The way of Monarc installation is to contribute to the development. Is this the purpose ?
Otherwise please use the VM https://www.monarc.lu/download/#virtual-machine
