Cancel remote event receiver ItemAdded

Is it possible to Cancel or Delete the item added with a RER ?
I’m trying the following code

List list = clientContext.Web.Lists.GetByTitle(properties.ItemEventProperties.ListTitle);
ListItem item = list.GetItemById(properties.ItemEventProperties.ListItemId);
clientContext.Load(item);
clientContext.ExecuteQuery();
if (some condition)
{
  item.DeleteObject();
  clientContext.ExecuteQuery();
  result.Status = SPRemoteEventServiceStatus.CancelWithError;
  result.ErrorMessage = 'Error";
}

But it’s not working. I get an error with “The folder you are trying to upload to has been moved or deleted.”
I need to use ItemAdded not ItemAdding.
Any ideas ?
Thank you !
