Maybe than something like that?

private fun loadJson(): Promise<String> {
    return window.fetch(Request("release.json"))
        .then { response ->
            if (response.ok) {
                response.text()
            } else {
                response.text().then { text ->
                    throw IllegalArgumentException("response was not ok, ${response.status}: ${response.statusText}<br/>$text")
                }
            }
        }
        .then { text ->
            text
        }
}
