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.

@23W
this issue is not actionable:
1) we don't know which app topology you are using.
2) we don't know if you are using B2C or not.

Please re-word your issue using the template we provide. We need to have repro steps in order to repro.

Thanks, I've updated issue.
This issue appeared on this Monday on all my app versions that uses MSAL 1.1.0-preview and MSAL 2.4.0-preview.

Thanks @23W
I'm just slightly puzzled by the constructor of PublicClientApplication with app-keys :)

[jmprieur]

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.

[jmprieur]

The fix is being rolled-out. this should be completed by tomorrow.

Thanks

Hello,

I still encounter the same issue. Does the fix need more time to be rolled-out?

Thanks

[jmprieur]

you are right. I asked the service team and it has not been fully rolled out yet.
It should be completed by end of the (Redmond) day.

[23W]

Has not fixed yet. I still see this script error :(

[23W]
