(w http.ResponseWriter, v httpResponse)

// WriteJSONResponse writes some JSON as a HTTP response.
func writeJSONResponse(w http.ResponseWriter, v httpResponse) {
	w.Header().Set("Content-Type", "application/json")

	data, err := json.Marshal(v)
	if err != nil {
		http.Error(w, err.Error(), http.StatusInternalServerError)
		return

	// Write will trigger sending Status code, so we cannot send a different status code afterwards.
	// Also this isn't internal error, but error communicating with client.
