Migrate Azure App Service to use Graph API instead of AAD Graph api

Hi Team,

I'm in a process of Migrating our Azure App Service application to use graph api instead of AAD Graph api.

I followed the steps which is mentioned in the article

https://github.com/microsoftgraph/msgraph-training-aspnetmvcapp/blob/main/Demos/03-add-msgraph/graph-tutorial/Helpers/GraphHelper.cs

unfortunately its not yet successful.

Throwing an exception

"OpenIdConnectMessage.Error was not null, indicating an error. Error: 'invalid_request'. Error_Description (may be empty): 'AADSTS90014: The required field 'nonce' is missing from the credential. Ensure that you have all the necessary parameters for the login request.

can someone point where the actual issue is?
