[Bug] ArgumentNullException when attempting to obtain a refresh token with Ping Identity.

[yowl]

Library version used

4.79.2.0

.NET version

Hi,

We are seeing an ArgumentNullException with the below stack when attempting to use a refresh token with PingIdentity. The application is created with

App.Instance.PublicClientApp = PublicClientApplicationBuilder.Create(Configuration.OpenIdClientId)
    .WithExperimentalFeatures() // Generic OIDC is experimental
    .WithOidcAuthority(Configuration.OpenIdAuthorityUri)
    .WithRedirectUri(redirect)
    .WithWindowsEmbeddedBrowserSupport()
#if DEBUG
    .WithLogging(logcallback, LogLevel.Verbose)
#endif
    .Build();

So we are using experimental features. The code to request a new token is

  var authResult = await lastClientApp.AcquireTokenSilent(scopes, loginTenantAccounts[0])
      .WithForceRefresh(true)
      .ExecuteAsync()
      .ConfigureAwait(false);

Solution 1:

Do I understand that you migrated your app from MSAL 2.x to 3.0.3-preview?

For .NET Framework and .NET desktop, if that's the case and you want to keep your token cache, you 'd want to do a one-time migration:

https://github.com/AzureAD/microsoft-authentication-library-for-dotnet/wiki/MSAL.NET-3-released#example-of-code-showing-how-to-migrate-from-msalnet-v2-to-msalnet-v3

try
 {
  args.TokenCache.DeserializeMsalV3(serializedData);
 }
 catch (MsalUnexpectedCacheFormatException)
 {
  args.TokenCache.DeserializeMsalV2(serializedData);
 }

but here this is Xamarin apparently, so the token cache serialization is not customizable.

It might make sense for us to take a look at the migration code you shared to avoid our users logging in again once we put the new MSAL v3 app to production.

However, I don't think it makes a difference for the issue posted here, as we experience this error on completely fresh installations of our app using the v3.0.3-preview.

It looks to me like there is a missing null check when getting the refresh token.

Have read the suggestions and don't think they apply. As far as I know this has never worked and is not a migration issue. The same code works for Entra, so I'm assuming this problem is due to slight differences in the way Ping Identity works.
