IdentityModel.OidcClient version: 4.0.0-preview.7 and lower same problem too
WinForm .Net 5.0

In Auth0ClientBase.cs, when I call
var result = await OidcClient.LoginAsync(loginRequest, cancellationToken);
I always receive the error: “An error occurred during login: sub claim is missing from userinfo endpoint”

Hi @msavard,

I’m glad you were able to find the rule that was causing the issue!

Yes, but for find the mistake, a convert completly in .Net5

auth0-WinFormsWPF-oidc-samples-master with replace webbrowser in DLL with the real WebBrowser in System.Windows.Forms

And I find your Nuget source code in your Git repository for:
IdentityTokenValidator
OidcClient

Ok for me, but not really easy for beginner
