I have a multi-tenant application in Microsoft Entra ID, which I use for Single Sign-On in my .NET 6 (API) and Angular 7 application as shown in the attached screenshots.
There are two issues I'm facing:
- After updating from .NET 3.1 to 6, I'm not able to log in using SSO on my local machine. I suspect this may be due to a proxy server change, but I'm not sure how to debug this issue properly.
- When I click on my application in the My App section of Office apps, I am getting an exception message (this is not related to updating .NET version). The exception message is:
System.Exception: An error was encountered while handling the remote login. ---> System.Exception: OpenIdConnectAuthenticationHandler: message.State is null or empty.
Implementation:
Startup.cs
Controller:
My App from microsoft app section:
Developer technologies | ASP.NET | ASP.NET Core
Microsoft Security | Microsoft Entra | Microsoft Entra ID

2023-12-22T09:42:23.5233333+00:00 The error message "OpenIdConnectAuthenticationHandler: message.State is null or empty" typically occurs when the state parameter is not properly set during the authentication flow. This can happen if the state parameter is not included in the authentication request or if it is lost during the authentication flow.
Are you setting the state parameter correctly in your request.
In case the above does not work for you, please send us an email on azcommunity [at] microsoft [dot] com referencing this issue with a subject line "ATTN:shweta" and we will help you with alternative support options on this.
Thanks,
Shweta
