JSON-LD SiteNavigationElement：子页面架构无法识别 itemListElement 属性

Question

我有一个问题，我正在尝试使用“SiteNavigationElement”类型方案为我的网页制作 JSON-LD 代码。

但是当我尝试验证它时。它被拒绝并收到 5 次警告。 这让我很好奇。因为一旦我有了一个没有子页面的一级 JSON-LD 代码，它就可以很好地验证。

但是当我添加子页面时它会生成警告。

从波兰语翻译过来，验证者说：

模式无法识别 itemListElement 属性（例如 schema.org）作为 SiteNavigationElement 对象的一部分。

我不知道如何解决这个问题。

一旦我启动子元素，它基本上就会给我一个警告。 但我想知道我在那里做错了什么？

    {

        "name": "contact",
        "description": "TEMP DESCRIPTION",

        "@context": "https://schema.org",
        "itemListElement": [
            {
                "@type": "SiteNavigationElement",
                "position": 1,
                "name": "Den Haag",

                "url": "https://example.com/contact/den-haag"
            },
            {
                "@type": "SiteNavigationElement",
                "position": 2,
                "name": "Haarlem",
                "description": "TEMP DESCRIPTION",
                "url": "https://example.com/contact/haarlem"
            }
        ]
    },

我确实重新开始了这个职位。我再次设置了上下文。但同样...没有子页面/子页面它效果很好。

没有子页面且没有警告的工作示例

一旦我启动子元素，它基本上就会给我一个警告。但 我想知道我在那里做错了什么？

您在不支持此属性的类型

itemListElement

中嵌套了一个子元素，例如属性

SiteNavigationElement

。要解决此问题，请使用类型 SiteNavigationElement 可用的属性。
