“ReferenceError: setTimeout” while merging two tabs into one pdf using Google Apps Script

Continuing my previous question, I want to merge two tabs of Google Sheets into one pdf. @Tanaike proposed a solution that worked on this sheet as required. Here is the proposed code with javascript library:

function myFunction(e) {

   var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Form responses 1");
   SpreadsheetApp.flush();

   const output = [
    {sheetName: "Quan", range: "A2:Q28"},
    {sheetName: "Qual", range: "A1:I27"},
    ];

    var ss = SpreadsheetApp.getActiveSpreadsheet();
    const url_base = ss.getUrl().replace(/edit$/,'');
    const headers = {authorization: "Bearer " + ScriptApp.getOAuthToken()};
    const data = output.map(({sheetName, range}) => {
    const s = ss.getSheetByName(sheetName);
    const gid = s.getSheetId();
    const r = s.getRange(range);
    const r1 = r.getRow() - 1;
    const c1 = r.getColumn() - 1;
    const r2 = r1 + r.getNumRows();
    const c2 = c1 + r.getNumColumns();
    const url = `${url_base}export?exportFormat=pdf&format=pdf`
      + '&size=letter'
      + '&portrait=true'
      + '&fitw=true'
      + '&sheetnames=false&printtitle=false&pagenumbers=false'
      + '&gridlines=false'
      + '&fzr=false'
      + `&gid=${gid}&r1=${r1}&c1=${c1}&r2=${r2}&c2=${c2}`;
    const res = UrlFetchApp.fetch(url, {headers, muteHttpExceptions: true});
   
    if (res.getResponseCode() != 200) {
      console.log(res.getContentText())
      }
    return new Uint8Array(res.getContent());
     });
 
     const setTimeout = function(f, t) {
     Utilities.sleep(t);
     return f(); }
     const pdfDoc = await PDFLib.PDFDocument.create();
 
    for (let i = 0; i < data.length; i++) {
    const pdfData = await PDFLib.PDFDocument.load(data[i]);
    const pages = await pdfDoc.copyPages(pdfData, [...Array(pdfData.getPageCount())].map((_, i) => i));
    pages.forEach(page => pdfDoc.addPage(page));
    }
    const bytes = await pdfDoc.save();
    var folder = DriveApp.getFolderById('1t6ns346GNX_gP-uGkwE43egGhTCaWgKO');
    var pdf = folder.createFile(Utilities.newBlob([...new Int8Array(bytes)], MimeType.PDF, "sample1.pdf"));

    console.log(pdf.getUrl())
    sheet.getRange("AW7").setValue(pdf.getUrl());

}

The issue is this script works only for this Spreadsheet. If I copy it or access the other Spreadsheet with url then it shows the following error message:

ReferenceError: setTimeout is not defined (anonymous) @ JS
Library.gs:15 X @ JS Library.gs:15 (anonymous) @ JS Library.gs:15
(anonymous) @ JS Library.gs:15 (anonymous) @ JS Library.gs:15 a @ JS
Library.gs:15

In line 6 of the code, the statement is SpreadsheetApp.getActiveSpreadsheet(), I want to use SpreadsheetApp.openByUrl(). Any guidance would be much appreciated.
