c# - 无法从 Azure KeyVault 读取值。指定的用户没有有效的配置文件

Question

我们有多个服务器，在 IIS 上托管 ASP.NET 网站。在网站中，我们尝试从 Azure KeyVault 获取值。

在一台服务器中，由于某种原因，它无法从 Azure KeyVault 读取值，并出现错误“指定的用户没有有效的配置文件”。我们已经完成了调查、双重检查配置、文件权限 - 一切看起来都很好。还尝试调整 IIS 中的配置文件，但没有任何帮助。

这是堆栈跟踪:

有人遇到过类似的问题吗？

任何帮助将不胜感激。

我在这里回答了类似的问题:Function app in Azure could not load file or assembly 'Microsoft.Extensions.Logging.Abstractions'

一定要检查一下 - 可能是出于同样的原因。可能有一个 nuget 包需要不同版本的 Microsoft.Configuration.ConfigurationBuilders.Azure:2.0.0。但是，您安装的版本不兼容。
