Sends a request for which a response entity is not expected. It returns a CompletableFuture with a Result which holds an empty String as output and a HttpResponseAttributes.

In case of failure, the future will be exceptionally completed with a RequestException, which RequestException.getErrorMessage() will have its payload made repeatable through the use of the streamingHelper

Specified by:

bodylessRequest in interface RestConnection

Parameters:

requestBuilder - the RestRequestBuilder on which the request has been configured

responseTimeoutMillis - the request timeout in milliseconds

streamingHelper - the StreamingHelper in case an error message needs to have its payload made repeatable

Returns:

a CompletableFuture
