Sometimes when a user sends a message or otherwise works with an act, an error 500 appears. This only happens when logged in via AAD. The parameters dictionary contains a null entry for parameter 'type' of non-nullable type 'Alvao.ServiceDesk.ServiceDeskWebApp.Models.Database.tActKind+ActKind' for method 'System.Web.Mvc.ActionResult New(System.Nullable`1[System.Int32], System.Nullable`1[System.Int32], ActKind, SendingModes, System.Nullable`1[System.Boolean], System.Nullable`1[System.Boolean], System.String, System.Nullable`1[System.Int32], System.String, Boolean)' in 'Alvao.ServiceDesk.ServiceDeskWebApp.Controllers.ActController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
