Prestashop 1.7.7.5: FrameworkBundleAdminController: $this->module->getPathUri() returns an error - prestashop

Question

In my admin module's controller's listMappingsAction action, I want to show a Vue.JS template, passing two variables that need to call $this->module->getPathUri() to be assigned a value:
<?php
namespace XYZ\Controller;
use PrestaShopBundle\Controller\Admin\FrameworkBundleAdminController;
use PrestaShopBundle\Security\Annotation\AdminSecurity;
class AutomatizedMappingController extends FrameworkBundleAdminController
{
/**
* #AdminSecurity("is_granted('read', request.get('_legacy_controller'))", message="Access denied.")
*/
function listMappingsAction() {
return $this->render('#Modules/XYZ/views/templates/admin/app.html.twig', [
'XYZ' => [
'pathApp' => $this->module->getPathUri() . 'views/js/app.js',
'chunkVendor' => $this->module->getPathUri() . 'views/js/chunk-vendors.js',
]
]);
}
}
The use of $this->module->getPathUri() results in this error being displayed:
Attempted to call an undefined method named "getPathUri" of class "XYZ\Controller\AutomatizedMappingController". [Symfony\Component\Debug\Exception\UndefinedMethodException 0]
What could I call to make it work? The docs don't mention this use case... https://devdocs.prestashop.com/1.7/modules/concepts/templating/vuejs/faq/#how-to-send-data-from-symfony-controller-to-vuejs

First of all you need to know there is a difference between a module and a admin-controller. You cannot call $this->module->getPathUri() because your not using a extends ModuleAdminController, extends ModuleFrontController, extends Module ...
So you can only call $this->module if your actually using files inside a module.
Since i don't know which path you are trying to go to ill pass you a few variables which you might be able to use.
$this->module->name = crezzurmodulename
$this->module->getLocalPath() = C:\yourstore/modules/crezzurmodulename/
$this->module->getPathUri() = /yourstore/modules/crezzurmodulename/
_MODULE_DIR_ = /yourstore/modules/
_PS_MODULE_DIR_ = C:\yourstore/modules/
__DIR__ = C:\yourstore\modules\crezzurmodulename\controllers\front
_PS_CAT_IMG_DIR_ = C:\yourstore/img/c/
_PS_PROD_IMG_DIR_ = C:\yourstore/img/p/
_PS_TMP_IMG_DIR_ = C:\yourstore/img/tmp/
_PS_ROOT_DIR_ = C:\yourstore
_PS_CACHE_DIR_ = C:\yourstore/var/cache/dev\
_PS_BASE_URL_ = http://127.0.0.1
__PS_BASE_URI__ = /yourstore/
_PS_TRANSLATIONS_DIR_ = C:\yourstore/translations/
_PS_BASE_URL_SSL_ = http://127.0.0.1 or https://127.0.0.1
_PS_DOWNLOAD_DIR_ = C:\yourstore/download/
_PS_COL_IMG_DIR_ = C:\yourstore/img/co/
_PS_SHIP_IMG_DIR_ = C:\yourstore/img/s/
_PS_UPLOAD_DIR_ = C:\yourstore/upload/
