Error on update #2763

Hi Guys

I keep on getting this error every time I do an update. "System.InvalidOperationException: Attaching an entity of type 'Synapsis.SmartRentals.RentalContracts.RentalContract' failed because another entity of the same type already has the same primary key value. This can happen when using the 'Attach' method or setting the state of an entity to 'Unchanged' or 'Modified' if any entities in the graph have conflicting key values. This may be because some entities are new and have not yet received database-generated key values. In this case use the 'Add' method or the 'Added' entity state to track the graph and then set the state of non-new entities to 'Unchanged' or 'Modified' as appropriate." Below is my update code

var property = Mapper.Map<Property>(input);
  await _propertyRepository.UpdateAsync(property);

    Hi,

    Lastly, can you share the data you send from client to server for this field ?

    public List<ContractDto> PropertyContract { get; set; }
