AbpBoilerPlate EF Core 3.0 StackOverflowException during UpdateAsync - aspnetboilerplate

Question

Recently I've experienced this error while trying to update entities in MS SQL Database.
I have two models:
[AutoMap(typeof(Employees))]
[Table("Employees")]
public class Employees : FullAuditedEntity
{
public Employees()
{
EmployeesAdresses = new HashSet<EmployeesAdresses>();
WorkTimeEntries = new HashSet<WorkTimeEntries>();
ContractEntries = new HashSet<ContractEntries>();
}
public string Name { get; set; }
public string Surname { get; set; }
public string Description { get; set; }
public bool IsActive { get; set; }
public ICollection<EmployeesAdresses> EmployeesAdresses { get; set; }
public ICollection<WorkTimeEntries> WorkTimeEntries { get; set; }
public ICollection<ContractEntries> ContractEntries { get; set; }
[NotMapped]
public List<GroupRelations> GroupRelations { get; set; }
}
[AutoMap(typeof(EmployeesAdresses))]
[Table("EmployeesAdresses")]
public class EmployeesAdresses : FullAuditedEntity
{
public string Street { get; set; }
public string HouseNumber { get; set; }
public string ApartmentNumber { get; set; }
public string PostalCode { get; set; }
public string City { get; set; }
public string Phone { get; set; }
public string Email { get; set; }
public bool IsDefault { get; set; }
public bool IsActive { get; set; }
[ForeignKey("Employees")]
public int EmployeeId { get; set; }
public virtual Employees Employee { get; set; }
}
I am trying to update Employee Adress using simple appservice:
public async Task UpdateEmployee (Employees employeeInput)
{
try
{
var _employee = await _employeesRepository.GetAllIncluding(x => x.EmployeesAdresses).Where(x => x.Id == employeeInput.Id).SingleOrDefaultAsync();
if (_employee == null)
throw new Exception($"Brak pracownika o ID: {employeeInput.Id}");
_employee.EmployeesAdresses.Clear();
_employee.WorkTimeEntries.Clear();
ObjectMapper.Map(employeeInput, _employee);
await _employeesRepository.UpdateAsync(_employee);
}
catch (Exception ex)
{
throw new UserFriendlyException(#"Wystąpił błąd podczas aktualizacji pracownika.", ex.Message, ex.InnerException);
}
}
I am getting StackOverFlowException and I really don't know whats the issue. Last error on stacktrace in diagnostic tool event tab is StringCompare error.
Did you experience such a behaviour? Any ideas what might be a problem?
