Error object reference not set to an instance of an object:

var Data = result.items.Select(e => new { PartID = e.create._id, IsUpdated = e.create.error != null && e.create.error.reason !=null && !e.create.error.reason.Contains("document already exists") ? 0 : 1, ErrorStatus = e.create.error == null  | (e.create.error.reason!=null && e.create.error.reason.Contains("document already exists")) ? null : e.create.error.reason }).ToList();

ElasticPartialUpdat.Create.error.get returned null.
