My Code
static async generatePDFFromNunjucksTemplate(
template: string,
data: Record<string, unknown>,
pdfOptions?: PDFOptions,
logger?: Logger,
): Promise<string> {
const templatePath = Path.join(__dirname, '../../templates');
const engine = nunjucks.configure(templatePath);
const html = engine.render(template, data);
logger?.info('before browser launch');
const browser = await puppeteer.launch({
headless: true,
args: [
'--no-sandbox',
'--disable-setuid-sandbox',
'--disable-dev-shm-usage',
'--disable-accelerated-2d-canvas',
'--disable-gpu',
'--no-zygote',
'--single-process',
],
});
logger?.info('after browser launch');
const page = await browser.newPage();
logger?.info('after page launch');
await page.setContent(html, { waitUntil: 'networkidle0' });
logger?.info('after load content launch');
const pdfBuffer = await page.pdf(
merge(
{
format: 'A4',
printBackground: true,
},
pdfOptions,
),
);
logger?.info('after to pdf');
await browser.close();
logger?.info('after browser close');
return Buffer.from(pdfBuffer).toString('base64');
}
The log after the browser open works fine, it breaks at the newPage command.
Error
Network.enable timed out. Increase the 'protocolTimeout' setting in launch/connect calls for a higher timeout if needed.
