Hi @PanithanK,

Could you confirm you have title, subject, author, description and lang in your document as demonstrated by the following sample?

<html lang="EN-US">
<head>
  <title>All-in-one PDF/UA Testcase</title>
  <meta name="subject" content="PDF/UA all-in-one"/>
  <meta name="author" content="openhtmltopdf.com team"/>
  <meta name="description" content="An example containing everything for easy testing"/>

It seems to be saying there is a problem with the XMP metadata. However, I have tested with PDFBOX preflight validator, VeraPDF validator and this online XMP validator and they all pass.

Could you perhaps try to validate with that online validator and see what is says?

P.S. I have noticed that if you have a PDF document open in Acrobat, the file will not be updated by FileOutputStream and will fail silently. Could you try closing Acrobat, regenerating the document and then opening Acrobat again to validate to make sure you are using the code you think you are? Thanks for persisting.

I'm not sure about this one. Anyone else got any ideas? Acrobat Pro is not very helpful here.
