Your Response object should have a body() method that lets you retrieve what has been responded to your call.

Your code should look like this:

try (Response response = client.newCall(res).execute();
     ResponseBody body = response.body()) {
    Data data = gson.fromJson(body.string(), Data.class);
} catch (IOException e) {
    e.printStackTrace();
}
