大家好！
我正在尝试使用ASP.NET Core实现OpenIDDict以保护我的Web API。但是，在我按照OpenIDDict github页面中的说明操作后，我在浏览器中遇到以下错误：
ArgumentException：必须提供“AuthenticationScheme”选项。 Microsoft.AspNetCore.Authentication.OAuth.OAuthMiddleware..ctor（RequestDelegate next，IDataProtectionProvider dataProtectionProvider，ILoggerFactory loggerFactory，UrlEncoder encoder，IOptions sharedOptions，IOptions options）
开发环境和软件版本：
你们对这个错误有什么看法吗？
