A friend of mine is signing up for a COPA account. He got through the registration, but when he clicks the account verification link, he gets:
Error.
An error occurred while processing your request
System.InvalidOperationException: Nullable object must have a value. at IdHouse.Web.Areas.Identity.Pages.Account.ConfirmEmailModel.OnGetAsync(String userId, String code, string returnUrl)
// [stack trace continues, lmk if you need more…]
Hmm, my friend still is seeing this issue and has not received an email reply, other than the automated one. Is this proving to be a difficult issue to fix?
