WCF Service update UPS. Operation is not valid due to the current state of the object.

Question

I try import custom data to custom user properties from my own wcf service (on sharepoint server machine), but i got
Message "Operation is not valid due to the current state of the object. "
on line
userProfile[PropertyConstants.Department].Value = "SDDDD";
Why i cant modify property value?
SPSecurity.RunWithElevatedPrivileges(delegate()
using (SPSite site = new SPSite("http://portal.local"))
SPServiceContext serviceContext = SPServiceContext.GetContext(site);
using (var web = site.OpenWeb())
Debug.WriteLine(web.CurrentUser); //Here AppPoolAccount user of current wcf service
Debug.WriteLine(WindowsIdentity.GetCurrent().Name); //Here too AppPoolAccount user of current wcf service
UserProfileManager userProfileMgr = new UserProfileManager(serviceContext);
ProfilePropertyManager profilePropMgr = new UserProfileConfigManager(serviceContext).ProfilePropertyManager;
ProfileSubtypePropertyManager subtypePropMgr = profilePropMgr.GetProfileSubtypeProperties("UserProfile");
UserProfile userProfile = userProfileMgr.GetUserProfile(accountName);
userProfile[PropertyConstants.Department].Value = "SDDDD";
userProfile.Commit();
My service running under domain\SPSvcAcc what have full permissions on UPS service, it's management account and UPS admin with full rights.
If i create console app with identical code and run it under SPSvcAcc account it working without problems
What i do wrong?
