Failed to find the pages descriptor.

[Jon2G]

I have a form PDF that is been filled with pdf-lib.

When I try to sign it using this tool I got the error: "Failed to find the pages descriptor."

I get the pdf buffer with: const pdf =await this.PdfDocument.save({ useObjectStreams: false }); const bufferPdf = Buffer.from(pdf)

It seems that my pdf does not have /Type /Catalog info

Any help is appreciated, thank you so much
