@nyel-dev Apologies for the delay in the reply. I changed your code slightly:

const chromium = require("chrome-aws-lambda");

exports.handler = async (event, context) => {
  let result = null;
  let browser = null;

  try {
    browser = await chromium.puppeteer.launch({
      args: chromium.args,
      defaultViewport: chromium.defaultViewport,
      executablePath: await chromium.executablePath,
      headless: chromium.headless,
      dumpio: false
    });

    let page = await browser.newPage();

    await page.setContent(`
      <html>
        <head>
          <title>Test</title>
        </head>
        <body>
          <h1>Testing.</h1>
        </body>
      </html>
    `);

    result = await page.pdf({
      format: "A4",
      printBackground: true,
      margin: {
        top: "1cm",
        right: "1cm",
        bottom: "1cm",
        left: "1cm"
      }
    });

    result = result.toString("base64");
  } catch (error) {
    return context.fail(error);
  } finally {
    if (browser !== null) {
      await browser.close();
    }
  }

  return context.succeed(result);
};

Which returns the expected base64-encoded PDF:
