angular - Angular 8 和 Service Worker 哈希不匹配

Question

我有一个 Angular 8 应用程序部署到启用/注册了服务工作者的服务器。我们似乎遇到的问题是站点随机加载旧版本而不是站点的最新版本。我认为这是因为服务人员，所以当我转到 /ngsw/state 时，我在调试时收到以下错误：

NGSW 调试信息：

当我检查服务器上的 index.html 文件时，我发现 ng build 之后构建的内容没有区别（部署后添加的额外行或任何其他更改）。我还从服务器检查了文件的哈希值，它显示了正确的哈希值：3103c76d8444cfb504f58967dfb578826e29a778，所以我不确定它是如何获得完全不同的哈希值的。

我能看到的唯一区别是，当我在站点上并进入开发人员工具时，所提供的 index.html 文件有几行额外的行（我认为它来自我们的监控 js 代理）然后服务器上的内容本身。不确定这是否是原因？

任何关于哪里/什么可能导致这种情况的指导将不胜感激
