所以我有一个应用程序，它使用vaadin(14(和keycapture弹簧引导适配器(11(。我查看了名为"；app authz springboot"；此处提供：https://github.com/keycloak/keycloak-quickstarts/tree/latest/app-authz-springboot当我执行该示例时，一切都很好，但当我将我的vaadin应用程序连接到该示例中的keycloft实例，并从同一示例的spring-half复制application.properties文件时，它无法设置策略强制配置。它给了我错误信息：
Could not lazy load resource with path[/VAADIN/build/webcomponentsjs/webcomponents-loader.js] from server
带有堆叠轨道：

keycloft配置为所有路径/*提供了通配符授权，因此keycloft端应该很好。事实上，在它设法创建配置并授予访问后不久

因此，错误必须在创建策略执行器配置的某个位置。你能帮我找出错误在哪里吗？这是我的应用程序属性
server.port=${PORT:8080}
vaadin.productionMode=false

因此，我使用的是版本11中的密钥掩蔽适配器，而不是导致错误的最新版本13。
