Как отправить сгенерированную картинку в BOTS LONG POLL API на Java

            String msg = message.getText();
            MessagesMethods method = vk.messages;
            if(msg.startsWith("/мемс ")) {
                String mem = msg.substring(5);
                method.send()
                        .setPeerId(message.getPeerId())
                        .setMessage("test")
                        .addPhoto(Util.getFile(mem))
                        .execute();
            }

код отправки выше

Util:

private static BufferedImage getImage(String msg) {
    BufferedImage bufferedImage = new BufferedImage(400, 400, BufferedImage.TYPE_INT_RGB);

    Graphics2D g = bufferedImage.createGraphics();

    Font stringFont = new Font( "SansSerif", Font.PLAIN, 50 );
    g.setFont(stringFont);
    g.drawString(msg, 0, 400);

    return bufferedImage;
}
public static File getFile(String msg) {
    File file = new File("C:\\Users\\Admin\\Desktop\\image.png");
    try {
        boolean b = ImageIO.write(getImage(msg), "png", file);
        System.out.println("Картинка создана: " + b);
    }
    catch (IOException e) {
        System.out.println("Не удалось создать изображение!");
        System.out.println(e.getMessage());
    }
    return file;
}

Вылетает ошибка при написании /мемс (любое слово)
