Application Insights：脚本错误未知

Application Insights: Script error at unknown

我们的一些客户端异常不包含任何详细信息：

Script error. at unknown

这些错误似乎与特定 OS 或浏览器无关：

有没有办法获取更多信息？

我想我已经有了答案。我们的脚本在 CDN 后面：

Browser exceptions Most browser exceptions are reported.

If your web page includes script files from content delivery networks or other domains, ensure your script tag has the attribute crossorigin="anonymous", and that the server sends CORS headers. This will allow you to get a stack trace and detail for unhandled JavaScript exceptions from these resources.
