FSharp.Data Http.RequestString doesn't work obtaining repositories via GitHub API

[persiyanov]

let FSHARP_REPOS_QUERY_STRING = @"https://api.github.com/search/repositories"


let reposJson = Http.RequestString(FSHARP_REPOS_QUERY_STRING,
                                        query = [("q", "language:F%23")],
                                        headers = [("Accept", "application/vnd.github.drax-preview+json")])

Выдает:

System.Net.WebException: Сервер нарушил протокол. Section=ResponseStatusLine
   в System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult)

Stopped due to error

Но, делая запрос через, скажем, hurl.it, все ок.

Добавил User-Agent и ок.

let FSHARP_REPOS_QUERY_STRING = @"https://api.github.com/search/repositories"


let reposJson = Http.Request(FSHARP_REPOS_QUERY_STRING,
                                        query = [("q", "language%3AF%23")],
                                        headers = [("Accept", "application/vnd.github.drax-preview+json"); ("User-Agent", "Foo")])
