Repro

string AppKey = "...My App Key...";

string[] AppScopes =
{
    // Users' scopes
    "User.ReadBasic.All",
    "User.Read",

    // Files' scopes
    "Files.ReadWrite",
    "Files.ReadWrite.All",
};

byte[] tokensStream = null;

var tokenCache = new TokenCache();
tokenCache.SetAfterAccess((TokenCacheNotificationArgs args) =>
{
    if (args.TokenCache.HasStateChanged)
    {
        lock (locker)
        {
            tokensStream = args.TokenCache.Serialize();
        }
    }
});

tokenCache.SetBeforeAccess((TokenCacheNotificationArgs args) =>
{
    lock (locker)
    {
        args.TokenCache.Deserialize(tokensStream);
    }
});

const string DefaultAuthority = "https://login.microsoftonline.com/common/";
var App = new PublicClientApplication(AppKey, DefaultAuthority, tokenCache);

var authResult = await App.AcquireTokenAsync(AppScopes, string.Empty, UIBehavior.ForceLogin, string.Empty);
var accessToken = authResult.AccessToken;

Expected behavior Login Form should work without JScript error.

Actual behavior Call PublicClientApplication.AcquireTokenAsync shows login form with JScript error: “Unable to get property ‘reject’ of undefined or null reference.” Script URL: https://secure.aadcdn.microsoftonline-p.com/ests/2.1.8395.17/content/cdnbundles/oldconvergedlogin_pcore.min_z2qsp8b10e2xrib0uwoksg2.js See screenshot bellow. If user continues execution by pressing “Yes”, login finished with valid access token.

Thanks @23W there is an issue on the service side (AAD Login Page). It’s fixed, but still need to be rolled out. Leaving the issue open until it’s deployed.
