Error while trying to add page from a copy

[SamuelLANDIS]

What were you trying to do?

I was trying to add a page in a new PDF Document from another file

How did you attempt to do it?

Below is all my code, with comments My file is "gestionPDF.mjs", ran with "nodemon" /node.js v19.3.0

/*
fichier dédié aux PDF
*/

import { degrees, PDFDocument, rgb, StandardFonts } from 'pdf-lib';
import * as fs from 'fs';


export async function fabriquePDF() {
    // lecture du template
    const template = 'PDF/TemplateBordereau.pdf';
    const contenuTemplate = fs.readFileSync(template);
    const T=await PDFDocument.load(contenuTemplate);
    const first=T.getPage(0);     // I added this to try to fix the Pb
    const { width, height } = first.getSize()       // also this

    // creation du nouveau document
    const pdfDoc = await PDFDocument.create();

    // copy du template en guise de fond
    const fond=await pdfDoc.copyPages(T,[0]);

    console.log(fond)       // OK
    console.log([width,height])     // OK : Known ([540,780])
    

    // ajout de la page
    pdfDoc.addPage(fond);           // Not Working (see just below)



    const pdfBytes = await pdfDoc.save()
    fs.writeFileSync("PDF/BIDON.PDF", pdfBytes);
}


fabriquePDF();

TemplateBordereau.pdf

In my case , I wanted to add from 1 pdf to another a page

try {
     pdfDoc.insertPage(0, existingPage);
 } catch (error) {
    console.log(error);
 }

This error occurs because you're passing something that isn't a page. In my case, it was an array of pages.
