我正在尝试让Let的加密与Azure应用程序一起使用，但是我收到以下错误：
Microsoft.IdentityModel.Clients.ActiveDirectory.AdalServiceException: AADSTS70001:

我遵循了这个指南：https://gooroo.io/GoorooTHINK/Article/16420/Lets-Encrypt-Azure-Web-Apps-the-Free-and-Easy-Way/20073但是在第三点之前得到了错误。
我没有得到错误，因为我应该使用正确的应用程序ID：
PS C:\WINDOWS\system32> $app.ApplicationId
Guid
