如何解决“IDX20804：无法从以下位置检索文档：'[PII隐藏]'”C＃中的错误

Question

尝试获取访问令牌以在我的WebApi中使用MS Graph。但是不断得到这个错误，

[TaskCanceledException：任务被取消。] System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess（任务任务）+167。 。

[IOException：IDX20804：无法从以下位置检索文档：'[PII is hidden]'。] Microsoft.IdentityModel.Protocols.d__8.MoveNext（）+ 662 System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess（Task task）+99。 。 [InvalidOperationException：IDX20803：无法从以下位置获取配置：'[PII is hidden]'。] Microsoft.IdentityModel.Protocols.d__24.MoveNext（）+ 1586 System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess（Task task）+99

尝试了我可以在网上找到的所有修复程序。

我使用这个repo作为auth部分的参考。

我怎样才能解决这个问题？

同样在这里，我已经阅读了下面的内容并没有成功。我的设置正在运行，但后来我试图在另一台机器上加载它并遇到这个问题。

这是堆栈跟踪，我为我运行的两个不同的应用程序获得了http状态400和404。

解决方案：原来我没有在appsettings.json中配置AzureAD。我忘了设置我的User Secrets来配置有效凭据的AzureAD。

您需要为AzureAd设置以下凭据。

{
  "AzureAd": {
    "TenantId": "SOMETHING.onmicrosoft.com",
    "ClientId": "SOMETHING",
    "ClientSecret": "SOMETHING"

  }
}
