C# ASP.NET核心反应模板-Can'；找不到客户端id

我使用配置了个人帐户登录的React模板创建了一个ASP.NET Core 3.0应用程序

从那以后，我把它升级到了3.1版，所有的东西都可以编译和构建

但是，在运行时，我在默认控制器中得到以下错误，即

OIDCConfiguration controller

：

System.InvalidOperationException
  HResult=0x80131509
  Message=Client 'MyApp' not found.
  Source=Microsoft.AspNetCore.ApiAuthorization.IdentityServer
  StackTrace:

   at Microsoft.AspNetCore.ApiAuthorization.IdentityServer.DefaultClientRequestParametersProvider.GetClientParameters(HttpContext context, String clientId)
   at MyApp.Web.Controllers.OidcConfigurationController.GetClientRequestParameters(String clientId) in C:\Users\Baha\source\repos\MyApp\src\Web\Controllers\OidcConfigurationController.cs:line 22

   at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.Next(State& next, Scope& scope, Object& state, Boolean& isCompleted)
   at Microsoft.AspNetCore.Mvc.Infrastructure.ControllerActionInvoker.InvokeNextActionFilterAsync()

控制器中的

clientId

参数源自React文件，具体地说是

apiaAuthorizationConstants.js

变量

ApplicationName

我对此有点迷茫，但是使用3.1版的React模板创建一个新项目运行良好

有没有人经历过这一点，或者有人给了我们一些提示，接下来该怎么办
