I am using Elasticsearch5.4 and Nest5.4 for creating Index. Its showing an error while executing IndexData

```
 public bool IndexData<T>(T data, string indexName = null, string mappingType = null)
     where T : class, new()
    {
        if (client == null)
        {
            throw new ArgumentNullException("data");
        }
        var result = this.client.Index<T>(data,
          c => c.Index(indexName).Type(mappingType));           
        return result.IsValid;
    }

```

Error showing
