Document Templates preview and PDF generation fail on Zurich — HTML→PDF conversion returns no bytes

[Tejas9]

I’m facing an issue on a Zurich family instance with Document Templates and PDF Generation Utilities. Here’s the scenario:

• In my Yokohama PDI, clicking Preview on an HTML Document Template works fine and generates a PDF.
• On the client Zurich instance even for OOB records, clicking Preview on the same type of template fails with:
  “Unable to preview document due to an error.”

Troubleshooting Done

• Verified plugins: Document Templates and PDF Generation Utilities are active.

• Tried minimal HTML (“Hello World”) in both Document Templates and direct API calls.

• Used Document Templates API:

   new sn_doc.GenerateDocumentAPI().generateDocumentForTask('<record_sys_id>', '<template_sys_id>', 'DocTemplate_Test.pdf');

→ Fails with HTML→PDF conversion error (pdfOS is null).

Tried PDFGenerationAPI smoke test:

var html = '<h1>Hello PDF</h1><p>This is a smoke test.</p>';
new sn_pdfgeneratorutils.PDFGenerationAPI()
  .convertToPDF(html, 'sn_hr_core_case_compensation', '<record_sys_id>', 'HelloSmoke.pdf', '<font_family_sys_id>');

→ Also fails with:

Conversion failed. Cannot invoke "java.io.ByteArrayOutputStream.toByteArray()" because "pdfOS" is null

Ask

• Has anyone seen this pdfOS is null error in Zurich?
• Is there a known fix or patch for HTML→PDF conversion failures?
• Any additional configuration needed for Font Families or converter settings?

Any guidance or workaround would be greatly appreciated!
Thanks in advance.
