Generate pdf with pdfKit packingList

Question

I need to generate a pdf of the packing list with the data of the notes and the volume of the box, and I want it to be added to a new page when it exceeds 40 pages, I'm using pdfKit

I'm using this link https://pdfkit.org/demo/browser.html

I need to generate a pakingList several pages

I tried that way but it doesn't work.

var doc = new PDFDocument({ size: 'A4'});
var stream = doc.pipe(blobStream());
 
const layoutX = { align: 'center' }
const layoutY = 20
let tableStartPos = 20
  
function generateInnerPdf(doc) {
    const notes = [
        { vehiclePlate: 'MTG7200', logisticName: 'PAC', numNf: 01 },
        { vehiclePlate: 'MTG7200', logisticName: 'PAC', numNf: 02 },
        { vehiclePlate: 'MTG7200', logisticName: 'PAC', numNf: 03 },
        { vehiclePlate: 'MTG7200', logisticName: 'PAC', numNf: 04 },
        { vehiclePlate: 'MTG7200', logisticName: 'PAC', numNf: 05 },
        { vehiclePlate: 'MTG7200', logisticName: 'PAC', numNf: 06 },
        { vehiclePlate: 'MTG7200', logisticName: 'PAC', numNf: 07 },
        { vehiclePlate: 'MTG7200', logisticName: 'PAC', numNf: 08 },
        { vehiclePlate: 'MTG7200', logisticName: 'PAC', numNf: 09 },
        { vehiclePlate: 'MTG7200', logisticName: 'PAC', numNf: 10 },
        { vehiclePlate: 'MTG7200', logisticName: 'PAC', numNf: 11 },
