我有一些代碼正在MSAL 1.1.0-alpha307上工作，但在1.1.0-預覽中它引發異常「客戶端信息爲空」，其中在HTTP響應中返回。該應用程序在AAD V2端點註冊並獲取MS Graph數據。從下面的堆棧跟蹤中，它看起來像能夠獲得Graph的令牌但不能緩存它。獲取「客戶端信息爲空」與MSAL 1.1.0-預覽
任何人都可以提出一個診斷/修復/解決方法嗎？
這是代碼：
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");
這是堆棧跟蹤：

同樣的問題在這裏，工作在開始，但稍後刷新令牌出現此異常。當你在5月17日問這個問題時，你找到了一個解決方法。 – rfcdejong
這應該是固定的。我已經向開發者進行了調查。我會回報我發現的。 –
我們的開發人員要求您安裝http://www.telerik.com/fiddler工具。從這種情況發生時捕獲請求/響應。您無法將其添加到評論中，因此請開始一個新問題並在其中包含提琴手數據。 –
