It sounds like you are having an issue with some articles not exporting images to PDF when using the script provided. Here are a few things to check:
Verify that the images are properly embedded in the articles. Make sure that the images are not being linked to externally and that they are embedded in the articles using the proper format (e.g. <img src="image.jpg">)
Check that the images are in a format that can be exported to PDF. Some image formats, such as .gif, may not be compatible with the PDF export process.
Verify that the images are being properly referenced in the script. Make sure that the script is correctly identifying and pulling in the images from the articles.
Check if there is any restriction in the script that is preventing the images to be exported. For example, if the script only exports images of certain dimensions or file types, this may be the cause of the issue.
Check if there is any issue with the PDF generator library that you are using. Verify that the library is up to date, and that it is configured correctly to export images.
It would be helpful if you can provide more information about the format and location of the images in the articles, as well as any error messages or issues that you are encountering.
// Define kbID variable to get the sysparm_kbID value
var kbID = this.getParameter('sysparm_kbID');
// Define kbContent variable as empty string
var kbContent = '';
// Define kb variable as new GlideRecord object
var kb = new GlideRecord("kb_knowledge");
// Query the kb table with sysparm_kbID value
if (kb.get(kbID)) {
// Get the number, short_description and text from kb table
kbContent = kb.number.fontsize(5).bold() + ' : ' + kb.short_description.fontsize(5).bold();
kbContent += "\n\n" + kb.text.toString();
var fileName = kb.number + '_' + kb.getValue('short_description');
} else {
// If the kb record is not found, throw an error
throw "Error: KB article not found with the given sysparm_kbID value.";
}
// Define sysAtt variable as new GlideRecord object
var sysAtt = new GlideRecord('sys_attachment');
// Query the sys_attachment table with table_sys_id and file_name, content_type
sysAtt.addEncodedQuery("table_sys_id=" + kbID + "^file_nameSTARTSWITH" + kb.number + "_" + "^content_type=application/pdf");
if(!sysAtt.query()) {
// If the query returns no results, throw an error
throw "Error: No attachment found with the given sysparm_kbID value.";
}
while (sysAtt.next()) {
// Delete the existing attachment before exporting a new copy
sysAtt.deleteRecord();
}
// Define expt variable as new PDFGenerationAPI object
var expt = new sn_pdfgeneratorutils.PDFGenerationAPI;
// Try to convert the KB article to PDF
try {
var result = expt.convertToPDFWithHeaderFooter(kbContent, "kb_knowledge", kbID, fileName);
return '/sys_attachment.do?sys_id=' + result.attachment_id;
} catch(ex) {
// If the PDF generation fails,
throw "Error: Failed to generate PDF for the KB article. " + ex;
}
In this updated version of the script, I've added error handling to check if the kb record is found or not with the given sysparm_kbID value, and if the query returns no results for the sys_attachment table. If any of these conditions is not met, the script throws an error with a relevant message. Additionally, I've added a try-catch block to handle any errors that may occur during the PDF generation process and throw an error with a relevant message.
Keep in mind that this is just an example and you may need to adapt it to fit your specific use case.
It's also important to test your code thoroughly, to make sure that it works as expected and that it doesn't cause any unintended issues.
Please let me know if you have any question.
Mark as helpful if it solves your issue
