CurrentSessionToken is null

[dn_garza]

System.NullReferenceException: 'Object reference not set to an instance of an object.'

SoftPro.Select.Service.Runtime.RuntimeContext.CurrentSessionToken.get returned null.

In previous work sessions, CurrentSessionToken was not null. I'm not sure what caused it to become null. Is there anything that I could have possibly done on my end to make this so? Is there any way to reimplement the CurrentSessionToken?

Is this code in a server package or something else? Is there a code snippet you could share?

In order to help, please provide the code for the area that is failing and the complete call stack. Thanks.

This is in a server package that I'm running in debug mode

Code: Select all

using (RuntimeContext.Impersonate(RuntimeContext.CurrentSessionToken, true))
                        {
                            // Set default profile.
                            IProfileManager pm = GetService<IProfileManager>();
                            IProfileInfo pi = pm.Profiles.Where(t => t.Name == "Default").FirstOrDefault();
                            IProfile profile = pm.GetProfile(pi);
                            pm.ActiveProfile = profile;

                            IOrderStore os = GetService<IOrderStore>();

                            System.Diagnostics.Debug.WriteLine($"order length {orders.Length}");
                            for (int i = 0; i < orders.Length; i++)
                            {
                                // Fetch a new order from the order store.
                                var spec = new OrderCreationSpec();
                                spec.SettlementType = SettlementType.CDF;
                                IOrder order = os.NewOrder(spec);

                                // Cast to dynamic to make order handling easier.
                                dynamic o = (dynamic)order;

                                // Set a property.
                                o.Project = "Bendun";
                                o.Properties.Parcels.Identification = orders[i].TaxParcel;
                                o.SettlementLocation.Place.Address.Address1 = orders[i].Address1;
                                o.SettlementLocation.Place.Address.Address2 = orders[i].Address2;
                                o.SettlementLocation.Place.Address.City = orders[i].City;
                                o.SettlementLocation.Place.Address.Zip = orders[i].Zip;
                                o.SettlementLocation.Place.Address.County = orders[i].County;

                                // Get IState object.
                                IEnumManager enumMgr = GetService<IEnumManager>();
                                IState state = enumMgr.GetEnum<IState>().Values.Where(t => t.Code == orders[i].State).First();
                                o.SettlementLocation.Place.Address.State = state;

                                // Save the order in the database.
                                os.ApplyChanges(order);

                                orderIds.Add(orders[i].idSearchOrder);
                            }
                        }

Just for clarification, line 97 is the using statement where things are breaking.

[vmrvichin]

you can try using just an empty Impersonate block

Code: Select all

using (RuntimeContext.Impersonate())

I'm not going to pretend to fully understand what all the Impersonate blocks do, but from what I've been able to gather, it has something to do with threading and if the action that triggered the block of code running originated from the UI.

Thanks, this worked perfectly!
