Repro-ing the issue

Repro steps

1) I followed all the documentation at https://github.com/Azure-Samples/active-directory-aspnetcore-webapp-openidconnect-v2/blob/master/4-WebApp-your-API/4-1-MyOrg/README .md

2) When I run the client program, the example is loaded in the browser. 3) I authenticate to Microsoft with my organization account. 4) When I access the https://localhost:44321/TodoList resource, an internal error occurs.

Expected behavior Open resource page https://localhost:44321/TodoList displaying all to-do records.

Actual behavior An internal error occurs when accessing the resource.
