Hi,
Any update on this issue?

@Gptrnt,

You can use any of the following two ways to fix this problem:

Workaround 1:

Inside your ‘getHtmlContentFromBookMark’ method, instead of getting HTML String by using Document.toString() method, please save the document to HTML stream by using Document.save method. Please check the last lines of this function:

private static String getHtmlContentFromBookMark(String field, BookmarkCollection bookmarkCollection, Document document, SaveOptions saveOptions, int slNo) {
    try {
        ...
        ...
        Document dstHTML = generateDocument(document, extractedNodes);

        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        dstHTML.save(baos, saveOptions);
        return baos.toString("UTF-8");

        //return dstHTML.toString(saveOptions);
    }catch (Exception e){
        System.out.println("error while fetching bookmark of preamble "+ field + slNo );
    }
    return "";
}

Workaround 2:

If it is required that you must use the Document.toString() method, then please only replace your ‘htmlSaveOption’ method with the following:

private static HtmlSaveOptions htmlSaveOption() throws Exception {
    HtmlSaveOptions options = new HtmlSaveOptions();
    options.setSaveFormat(SaveFormat.HTML);
    options.setExportImagesAsBase64(true);
    options.setExportListLabels(ExportListLabels.AS_INLINE_TEXT);
    return options;
}

Hope, this helps.
