Byte[] to image conversion returning null

Question

I am developing a mobile application that send photos of the application to the server, made in springboot. When receiving the request with the image, via json, I try to convert String to Image. However, in the conversion it returns null. For some reason the conversion is not happening and not saving the image.

@PostMapping(value = "/paciente")
public void paciente(@RequestBody String foto) throws IOException {

    try {

        byte[] encoded = Base64.encodeBase64(foto.getBytes());
        System.out.println("Encoded retorna >" + encoded)
        ByteArrayInputStream input = new ByteArrayInputStream(encoded);
        System.out.println("URL retorna >" + input);
        BufferedImage image = ImageIO.read(input);
        System.out.println("IMAGE retorna >" + image);
        ImageIO.write(image, "jpg", new File("C:/Users/carlo/Downloads/SisCAF/images/myImage1.jpg"));
        System.out.println("image created");

    } catch (Exception e) {

    }
}

The exit: Encoded returns >[B@7646546e URL returns >java.io.Bytearrayinputstream@1b7a9dc1 IMAGE returns >null
