MSAL 1.1.0プレビューで「クライアント情報がnullです」を取得

Question

MSAL 1.1.0-alpha307で動作していたコードがいくつかありますが、1.1.0プレビューでは「クライアント情報がnullです」という例外がスローされます。 HTTP応答で返されます。アプリケーションはAAD V2エンドポイントに登録され、MS Graphデータを取得します。下のスタックトレースからは、Graphのトーク​​ンを取得できるように見えますが、キャッシュできません。

誰でも診断/修正/回避策を提案できますか？

これはコードです：

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"); 

これは、スタックトレースです：

これは、AzureのActive DirectoryのV2.0エンドポイントのバグであることが判明しました。これは修正されています。
