Steps to Reproduce

async function launchBrowser() {
    try {
        const chromium = require('chrome-aws-lambda');
        console.info('launching chrome-aws-lambda browser');
        const browser = await chromium.puppeteer.launch({
            args: chromium.args,
            defaultViewport: chromium.defaultViewport,
            executablePath: await chromium.executablePath,
            headless: chromium.headless,
            ignoreHTTPSErrors: true,
        });
        return browser;
    } catch (e) {
        console.log(e);
    }
    finally {
        console.info('launching puppeteer browser');
    }
}

async function lambdaHandler(event, context) {
    console.info(`EVENT ${JSON.stringify(event, null, 2)}`);
    const browser = await launchBrowser();
    console.info('browser launched');
    const page = await browser.newPage();
    console.info('opened new tab');
    let bodyText = '';
    try {
        await page.goto(event.url, {
            waitUntil: 'networkidle0',
            timeout: 10 * 1000,
        });
        console.info('page opened');
        const stream = await page.pdf();
        bodyText = stream.toString("base64");
        console.info('pdf created');
    } finally {
        console.info('finally');
        await page.close();
        console.info('page closed');
        await browser.close();
        console.info('browser closed');
    }

    return {
        statusCode: 200,
        isBase64Encoded: true,
        headers: { "Content-type": "application/pdf" },
        body: bodyText
    };
