CraftCMS 无法加载模板

Question

在业务逻辑模块中加载模板时出现问题。 CraftCMS 版本 3.7.51 我的 app.php

'business-logic-module' => [
                    'class' => \modules\businesslogicmodule\BusinessLogicModule::class,
                    'components' => [
                            'businessLogicModuleService' => [
                                    'class' => 'modules\businesslogicmodule\services\BusinessLogicModuleService',
                            ]
                    ]
            ],

  'bootstrap' => ['business-logic-module']

在 /modules/businesslogicmodule/src/BusinessLogicModule.php

我定义了模板根：

   Event::on(View::class, View::EVENT_REGISTER_CP_TEMPLATE_ROOTS, function (RegisterTemplateRootsEvent $e) {
   if (is_dir($baseDir = $this->getBasePath().DIRECTORY_SEPARATOR.'templates')) {
       $e->roots[$this->id] = $baseDir;
   }
 });
    // Set this as the global instance of this module class
    static::setInstance($this);

    parent::__construct($id, $parent, $config);
}

我尝试将我的模板添加到

/modules/businesslogicmodule/src/templates/email/emailtemplate.twig

/templates/email/emailtemplate.twig

/modules/businesslogicmodule/src/services/templates/email/emailtemplate.twig

当我尝试发送 email

(new \modules\businesslogicmodule\services\BusinessLogicService())->SendEmail('test');

我收到错误错误：找不到模板

/modules/businesslogicmodule/src/services/BusinessLogicService.php

$html = Craft::$app->getView()->renderTemplate('email/emailtemplate')

知道这里可能有什么问题吗？
