如何在使用lambda@edge frunction将网站从cloudfront服务到私有s3 bucket时显示自定义404错误页

我正在使用 standard-redirects-for-cloudfront lambda@edge函数处理

“internal”从/foo/重定向到/foo/index.html和“external” 从/foo/index.html重定向到/foo/。

我在服务自定义错误页时遇到问题。

目前我已经在我的s3桶中的对象 /404.HTML (也被配置为S3静态网站的错误页面,无论如何都不应该请求,因为它应该是CloudFront负责的)。

在CloudFront我已经建立了 /副作用 作为404状态的自定义错误页。

如何设置它以返回错误页?
