No ResponseBodyInBytes or StatusCode when 401

[TioLuiso]

We have a Nginx that we use for authentication purposes. When it returns a 401, ElasticClient returns us a response with no status code and no ResponseBodyInBytes.

DebugInformation has the following

After a while, found out that the response that was returned by the connection (and that has the ResponseBodyInBytes and the 401 HttpStatusCode) is kept inside the OriginalException.

[Mpdreamz]

Which version of NEST is this?

[TioLuiso]

2.0.5

[Mpdreamz]

This is closely related to: #1901

and we have several tests that validate ResponseInBytes get set, but you still need to enable DirectStreaming. The statuscode should always be set though.

What are your connection settings and how do you instantiate the client?

When you do

var response = client.Call();

Does client.Call() return or do you get an ElasticsearchClientException being raised?

[Mpdreamz]

Ahh these tests only tests the ElasticsearchClientExeption (whether thrown or set on the response depending on throwing behaviour set on ConnectionSettings)

Caught the behaviour in a test will send a PR shortly, thanks for reporting @TioLuiso 👍
