Steps to Reproduce

const chromium = require('chrome-aws-lambda');
const puppeteer = require('puppeteer-core');

  async convertToPdf(request) {
    try {
      console.log('Starting puppeteer browser.');

      const browser = await chromium.puppeteer.launch({
        args: chromium.args,
        defaultViewport: chromium.defaultViewport,
        executablePath: await chromium.executablePath,
        headless: true,
        ignoreHTTPSErrors: true
      });

      console.log('Puppeteer launched: ' + !!browser);


      if (request.sections.length > 75) {
        throw new Error('Only 75 report sections are allowed');
      }

      let pdfs = await Promise.all(_.map(request.sections, async (section, $index) => {
        if (section.s3Pdf) {
          let s3Response = await s3.getObject({
            Bucket: section.s3Pdf.bucket,
            Key: section.s3Pdf.key
          }).promise();

          console.log(`PDF ${$index} retrieved successfully`);
          return s3Response.Body;
        }
        const page = await browser.newPage();

        page.setViewport(request.viewPort || {
          width: 1024,
          height: 600
        });

        section.options = section.options || {};

        console.log(`Loading section ${$index}...`);
        await page.setContent(this.fromBase64(section.html), {waitUntil: ['networkidle0']});
        console.log(`Section ${$index} Load complete. Converting html to pdf using puppeteer. Options: ${JSON.stringify(section.options)}`);

        let body = await page.pdf(_.assign({format: 'letter'}, section.options));

        console.log(`PDF ${$index} created successfully`);
        page.close();
        return body;
      }));

Previously my code was running properly on nodejs8.10 supported AWS Lambda function but after forcefully upgrade to nodejs12.x, my code starts to throw this error. I tried upgrading chrome-aws-lambda and puppeteer-core version to 2.1.1 and even the latest 5.3.1 but no luck on resolving the issue.
