我有一些在 MSAL 1.1.0-alpha307 上工作的代码，但在 1.1.0-preview 上它会抛出异常“客户端信息为空”，该异常会在 HTTP 响应中返回。该应用程序在 AAD V2 端点中注册并获取 MS Graph 数据。从下面的堆栈跟踪来看，它似乎能够获取 Graph 的令牌但无法缓存它。

任何人都可以建议诊断/修复/解决方法吗？

这是代码：

var bootstrapContext = ClaimsPrincipal.Current.Identities.First().BootstrapContext as BootstrapContext;
UserAssertion userAssertion = new UserAssertion(bootstrapContext.Token);
ClientCredential clientCred = new ClientCredential(ConfigurationManager.AppSettings["ida:Password"]);
ConfidentialClientApplication cca =
                    new ConfidentialClientApplication(ConfigurationManager.AppSettings["ida:ClientID"],
                                                      "https://localhost:44355", clientCred, null, null);
string[] graphScopes = { "Files.Read.All" };
AuthenticationResult result = await cca.AcquireTokenOnBehalfOfAsync(graphScopes, userAssertion, "https://login.microsoftonline.com/common/oauth2/v2.0");

这是堆栈跟踪：

这原来是 Azure Active Directory V2.0 端点中的一个错误。它是固定的。
