Error while running the following code:

here is all the code that I'm using to try download an PDF file that was created previously:

import puppeteer, { PDFOptions } from 'puppeteer';

interface Request {
  pageContent: string;
  pdfOptions?: PDFOptions;
}
class GeneratePDFFileService {
  async execute({ pageContent, pdfOptions }: Request): Promise<Buffer> {
    const browser = await puppeteer.launch ({ 
      headless: true, 
      args:['--no-sandbox'] 
    });
    const page = await browser.newPage();
    await page.setContent(pageContent);
    const pdfFileOptions = pdfOptions || {
      printBackground: true,
      format: 'a4',
      margin: {
        top: '2cm',
        left: '2cm',
        bottom: '2cm',
        right: '2cm',
      },
      preferCSSPageSize: true,
    };
    const pdf = await page.pdf(pdfFileOptions);
    await browser.close();
    return pdf;
  }
}
export { GeneratePDFFileService };

Here is the error:

Puppeteer version:
"puppeteer": "^13.1.3",

I've tried some tips in troubleshooting.md, but have no idea if I'm doing it right.
