Association one to one not working anymore when updating from 3.3 to 3.4.x

Hello ! I’m using HanaProvider and since i updated to 3.4.* associations like

        [Association(ThisKey = "CustomerId, Mandt", OtherKey = "Id, Mandt")]
        public Customer Customer { get; set; }

are not working anymore,

Error: Unhandled expression type: Default

i dont know if this is helping but that s what i get :

{value(HanaDataConnection).GetTable()
.Where(p => (p.Mandt == "100")).OrderBy(x => x.Name)
.Select(_s1 => new Agency() {Id = _s1.Id, Name = _s1.Name, Company = IIF((_s1.Company != null), new Company() {Id = _s1.Company.Id, Name = _s1.Company.Name}, default(Company))}).Take(201)}
