    }
    JsonRootObject jsonObject = new JsonRootObject();

    try {
        String jsonStrValue = content != null ? new String(content) : "";
        JsonRootObject json = LwM2mJson.fromJsonLwM2m(jsonStrValue);
        List<TimestampedLwM2mNode> timestampedNodes = parseJSON(json, path, model, nodeClass);
        if (timestampedNodes.size() == 0) {
            return null;
        } else {
            // return the most recent value
            return (T) timestampedNodes.get(0).getNode();
        }
    } catch (LwM2mJsonException e) {
        throw new CodecException(e, "Unable to deserialize json [path:%s]", path);
    }
}
