I have an ASP.NET website which uses Azure AD integration. When the site is deployed to test server i got an issue where Login process throws an null Reference Exception. The Login works when i login to server and do login from the same machine.
The code where Exception is thrown :
Line 80: AuthenticationContext authContext = new AuthenticationContext(Authority, new NaiveSessionCache(userObjectID));
Line 81: AuthenticationResult result = authContext.AcquireTokenByAuthorizationCode( code, new Uri(HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority)), credential, graphResourceId);
Line 82: AuthenticationHelper.token = result.AccessToken;
Line 83: return Task.FromResult(0);
The Exception is thrown on Line 81.
Exception Stack Trace:
[NullReferenceException: Object reference not set to an instance of an object.]
