TYPO3 Core

Following instructions on: https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ExtensionArchitecture/HowTo/BackendModule/CreateModuleWithExtbase.html#backend-modules-template

A simple backend controller action in TYPO3 13.4.0 leads to:

Call to undefined method TYPO3\CMS\Backend\Template\ModuleTemplate::setContent()

The example controller in my case would look like:

<?php

declare(strict_types=1);
namespace In2code\Lux\Controller;
use TYPO3\CMS\Backend\Attribute\AsController;
use TYPO3\CMS\Backend\Template\ModuleTemplateFactory;
use TYPO3\CMS\Extbase\Mvc\Controller\ActionController;

#[AsController]
final class AnalysisController extends ActionController
{
    public function __construct(
        protected readonly ModuleTemplateFactory $moduleTemplateFactory,
    ) {
    }

    public function dashboardAction(): ResponseInterface
    {
        $this->view->assign('someVar', 'someContent');
        $moduleTemplate = $this->moduleTemplateFactory->create($this->request);
        // Adding title, menus, buttons, etc. using $moduleTemplate ...
        $moduleTemplate->setContent($this->view->render());
        return $this->htmlResponse($moduleTemplate->renderContent());
    }
}
