我正在尝试使用创建包 symfony cmf。到目前为止一切正常，因为我能够编辑块但我无法保存我的内容。我收到以下错误：
Error occurred while saving

我正在使用的前端代码如下：
<div about="cms/test" typeof="schema:WebPage" xmlns:schema="http://schema.org/">
<h1 property="schema:headline">Hey bra</h1>
<div property="schema:text">
<h2>Welcome to the Symfony CMF Demo</h2>
<p>If you see this page, it means that the...</p>
</div>
<p>Brotha!</p>
<p property="schema:sdlkfj">hey</p>
</div>
我不确定的是“关于”属性的用途。“about=cms/test”只是我输入的一些任意值。我猜它代表了一些 phpcr-odm 节点，但我什至不确定在哪里设置该节点，甚至不确定这些文档是如何工作的。我已经为我的项目创建了我的 phpcr-odm 数据库并且 phpcr-odm 正在工作，但我不确定所有这些东西是如何工作的。我对 symfony cmf 真的很陌生。请让我知道如何使用 create bundle 保存内容，因为文档很烂。我还阅读了有意义的 phpcr-odm 学说文档，但我不确定如何将它与这个问题联系起来。
谢谢。
