SVGGraphics2D drawImage() NullPointerException

I am trying to create an SVG from a BufferedImage using the example at
https://xmlgraphics.apache.org/batik/using/svg-generator.html. The image is
a TIFF read from disk using Apache Commons Imaging. I can successfully
export this image to PNG. However cannot create an SVG. The code is

  public static void main(String[] args) {
    try {
      File inFile = new File(args[0]);
      BufferedImage sourceImage = ImageReadExample.imageReadExample(inFile);
      // Imaging.writeImage(sourceImage, new File("sourceImage.png"),
ImageFormats.PNG, null);

      // Get a DOMImplementation.
      DOMImplementation domImpl =
        GenericDOMImplementation.getDOMImplementation();

      // Create an instance of org.w3c.dom.Document.
      String svgNS = "http://www.w3.org/2000/svg";
      Document document = domImpl.createDocument(svgNS, "svg", null);

      // Create an instance of the SVG Generator.
      SVGGraphics2D svgGenerator = new SVGGraphics2D(document);

      // Ask the test to render into the SVG Graphics2D implementation.
      svgGenerator.drawImage(sourceImage, 0, 0, null);
      ...

When I end with `Imaging.writeImage(sourceImage, new
File("sourceImage.png"), ImageFormats.PNG, null);` a PNG is created.
However at `svgGenerator.drawImage(sourceImage, 0, 0, null);` I get this
stack trace:
