Microsoft Graph Subscription ExtensionError - Dele

问题:

Issue

• I currently have an Azure Active Directory Application that has a Microsoft Graph Webhook Subscription listening for new emails (messages) in a specified mailbox.
• The subscription has a scheduled task that renews the subscription's expiration date via an Update request. The subscription is targeted using its MS Graph Provided ID.
• Any DELETE or UPDATE request against this specific subscription fails. (See 'Error Response' below.)

Question

• I realize that this may be the same issue / bug as the question presented here: https://stackoverflow.com/a/53111286/7902641
• Has there been any fix / resolution / or workaround for this?
• If there has been a fix or this is a different problem altogether, what can I do to resolve this specific issue?
• Thanks!

Extra Info

• Somehow the Microsoft Graph ID for the subscription is...transformed? The original subscription ID is ( 528b79f1-....-....-....-360c0e1149e9 ) and the returned target ID is: ( Q0IzOUZ ... NEQ0Qg== ) .
• The executing UPDATE request originates from an ASP.NET CORE application, using the Microsoft Graph SDK (C#).
  • https://github.com/microsoftgraph/msgraph-sdk-dotnet
• However I have eliminated the SDK as the origination of the problem -- using a REST API tester (Insomnia), I achieve the same error result. The request URL looks like:
  • https://graph.microsoft.com/v1.0/subscriptions/528b79f1-....-....-....-360c0e1149e9
• I have also attempted to use the BETA version instead of v1.0. Unfortunately I get the same error result.

Configuration

• Application:
  • Registered Azure Active Directory Daemon Application
• Authentication Library:
  • MSAL
  • https://github.com/AzureAD/microsoft-authentication-library-for-dotnet
• Calling Application (generating the update / delete request):
  • ASP.NET CORE (2.1) - Web Api
  • Using MS Graph SDK (Github link posted above)

== Update ==

• The subscription in question has now expired and disappeared from my application's subscriptions list (timestamp, PST: 3/22/2019 8:45:22 AM).
• I will no longer be able to test against it (sorry S.O. posterity!).
• However, good news: now that the problem child (subscription) in question is gone, I was able to create a new subscription and restart my affected service. I am able to successfully submit get / update / delete requests against any newly created subscriptions.
