Convert PDF to TIFF doesn't work

I use the latest PDF 4.6.0 for java


I load a simple PDF File and try to convert it as TIFF, I tried differnet ways also with TIFFDevice, but still the same error!

I do this with the attached pdf file

        Resolution resolution = new Resolution(300);
       
        TiffSettings tiffSettings = new TiffSettings();
        tiffSettings.setCompression(CompressionType.LZW);
        tiffSettings.setDepth(ColorDepth.Format8bpp);
        tiffSettings.setSkipBlankPages(false);
       
        PdfConverter pdfConverter = new PdfConverter();
        pdfConverter.bindPdf("/app/images/tmp/1.pdf");           
        pdfConverter.setResolution(resolution);
           
        pdfConverter.saveAsTIFF("/app/images/tmp/1.tif", tiffSettings);

and get this error
