Hi, this issue was already reported. Fix will ship in release 6.0.3

If you want a quick workaround, you can adapt the following functions in server.js

async function processPageIntoPdfBuffer (browser, html, config)  {

    config.printBackground = true;
    config.margin = {
        top       : 0,
        bottom    : 0,
        left      : 1,
        right     : 1
    };

    return new Promise(async (resolve, reject) => {

        try {
            const page = await browser.newPage();
            //best way of loading according to https://github.com/GoogleChrome/puppeteer/issues/728
            await page.goto(`data:text/html;charset=UTF-8,${html}`, { waitUntil: 'networkidle0' });
            await page.emulateMedia('print');
            const buffer = await page.pdf(config);
            await page.close();
            resolve(buffer);
        }
        catch (ex) {
            reject(ex.message);
        }
    });
}

and

async function processPageIntoPngBuffer (browser, html, config)  {

    return new Promise(async (resolve, reject) => {

        try {

            const page = await browser.newPage();

            await page.goto(`data:text/html;charset=UTF-8,${html}`, { waitUntil: 'networkidle0' });
            await page.emulateMedia('print');
            const buffer = await page.screenshot(config);
            await page.close();
            resolve(buffer);

        } catch (ex) {
            reject(ex.message);
        }
    });
}

We recently discovered that this is a known issue with puppeteer loading the resources in the page. It needs to wait until all network activity is idle before generating the file buffer.

We are testing your version in you example of export pdf and we get a error. Could you check this problem?
