I have a function on Firebase to create a PDF file which times out every time. To investigate the issue I added debug logs with numbers. The source code of the function that I run is:
const createPDF = async (html, outputPath) => {
console.log(1);
let pdf;
try {
console.log(2);
const browser = await puppeteer.launch();
console.log(3);
const page = await browser.newPage();
console.log(4);
await page.emulateMediaType('screen');
console.log(5);
await page.setContent(html, {
waitUntil: 'networkidle0'
});
console.log(6);
pdf = await page.pdf({
// path: outputPath,
format: 'A4',
printBackground: true,
margin: {
top: "50px",
bottom: "50px"
}
});
console.log(7);
await browser.close();
} catch (e) {
console.error(e);
}
console.log(8);
return pdf;
};
The log says:
10:58:12.490 AM 1
10:58:12.492 AM 2
10:58:16.469 AM 3
10:58:31.236 AM Function execution took 20003 ms, finished with status: 'timeout'
The script works, when I deploy it locally. What did I do wrong?
I think launch should be used with argument { args: ['--no-sandbox'] }. I have found example with this approach here.
I created test combining provided code and helloworld cloud function, and indeed in always ended with timeout after 3. However when I used above argument it started to work fine. I tested it with 256MiB and 30 sec timeout.
Working code:
const puppeteer = require('puppeteer');
exports.helloWorld = async (req, res) => {
console.log(2);
const browser = await puppeteer.launch({ args: ['--no-sandbox'] });
console.log(3);
const page = await browser.newPage();
console.log(4);
let message = req.query.message || req.body.message || 'Hello World!';
res.status(200).send(message);
};
