Strange Exception Error DNN9 #3

Hi, I followed the instructions and have even recreated the DNN instance. Once I sucessfully authenticate with Azure, I get this error which I can access from the admin logs. Any ideas?

@jgrahamfcac I think I had a similar issue with one of our users. It boiled down to incorrect or missing (Azure) profile entry.

Id, Email, FirstName, LastName, DisplayName are the five properties the provider is trying to extract from the claim. If one of those is missing claims.FirstOrDefault(x => x.type == {type}).Value throws object reference exception which is what you're getting.

Have the user check their profile and make sure they specify First and Last names.

Hope this helps.
