For some PDFs plainAddPlaceholder returns error, although it works for w3dummy.pdf

See original GitHub issue

function signExistingPDF(pdfFile: string) {
  let pdfBuffer = readFileSync(pdfFile);
  pdfBuffer = plainAddPlaceholder({
      pdfBuffer,
      reason: 'I have reviewed it.',
      // signatureLength: 1612,
  });

  return pdfBuffer;
}

Hi @vbuch, looks like the issue has been resolved with the latest changes. Thanks for fixing it.

I think this issue can be marked as fixed until @vologab @lucasmassi has some other points.
