hi, im using nest v6 and it seems to be a bug or me doing something wrong..

when i follow this example:  
var request = new IndexExistsRequest(index);  
var result = client.IndexExists(request);  
i get this error:  
Elasticsearch.Net.UnexpectedElasticsearchClientException : Object reference not set to an instance of an object.  
---- System.NullReferenceException : Object reference not set to an instance of an object.  
at Elasticsearch.Net.Transport`1.Request[TResponse](HttpMethod method, String path, PostData data, IRequestParameters requestParameters) in c:\Projects\elastic\net-master\src\Elasticsearch.Net\Transport\Transport.cs:line 86 at Elasticsearch.Net.ElasticLowLevelClient.IndicesExists[TResponse](String index, IndexExistsRequestParameters requestParameters) in c:\Projects\elastic\net-master\src\Elasticsearch.Net\ElasticLowLevelClient.Generated.cs:line 1164 at Nest.LowLevelDispatch.IndicesExistsDispatch[TResponse](IRequest`1 p)

but if i run it async, it works:  
var request = new IndexExistsRequest(index);  
var result = client.IndexExistsAsync(request).Result;
