I am using puppeteer on Google App Engine with Node.JS
whenever I run puppeteer on app engine, I encounter an error saying
Navigation failed because browser has disconnected!
This works fine in local environment, so I am guessing it is a problem with app engine.
const browser = await puppeteer.launch({
ignoreHTTPSErrors: true,
headless: true,
args: ["--disable-setuid-sandbox", "--no-sandbox"],
});
This is my app engine's app.yaml file
runtime: nodejs12
env: standard
handlers:
- url: /.*
secure: always
script: auto
-- EDIT--
It works when I add --disable-dev-shm-usage argument, but then it always timeouts. Here are my codes.
const browser = await puppeteer.launch({
ignoreHTTPSErrors: true,
headless: true,
args: [
"--disable-gpu",
"--disable-dev-shm-usage",
"--no-sandbox",
"--disable-setuid-sandbox",
"--no-first-run",
"--no-zygote",
"--single-process",
],
});
const page = await browser.newPage();
try {
const url = "https://seekingalpha.com/market-news/1";
const pageOption = {
waitUntil: "networkidle2",
timeout: 20000,
};
await page.goto(url, pageOption);
} catch (e) {
console.log(e);
await page.close();
await browser.close();
return resolve("error at 1");
}
try {
const ulSelector = "#latest-news-list";
await page.waitForSelector(ulSelector, { timeout: 30000 });
} catch (e) {
// ALWAYS TIMEOUTS HERE!
console.log(e);
await page.close();
await browser.close();
return resolve("error at 2");
}
...
It seems the problem was app engine's memory capacity.
When memory is not enough to deal with puppeteer crawling,
It automatically generates another instance.
However, newly created instance has a different puppeteer browser.
Therefore, it results in Navigation failed because browser has disconnected.
The solution is simply upgrade the app engine instance so it can deal with the crawling job by a single instance.
default instance is F1, which has 256M of memory, so I upgraded to F4, which has 1GB of memery, then it doesn't show an error message anymore.
runtime: nodejs12
instance_class: F4
handlers:
- url: /.*
secure: always
script: auto
For me the error was solved when I stopped using the --use-gl=swiftshader arg.
It is used by default if you use args: chromium.args from chrome-aws-lambda
I was having that error in a deploy, the solution for this problem is change some parameters in waitForNavigation:
{ waitUntil: "domcontentloaded" , timeout: 60000 }

I have use puppeteer with http proxy
This is the config for puppeteer:
let config = {
userDataDir: `./puppeteer-cache/dev_chrome_profile_${hash}`,
headless: false,
args: [
`--proxy-server=${newProxyUrl}`,
'--ignore-certificate-errors',
'--disable-web-security',
'--disable-features=IsolateOrigins,site-per-process,BlockInsecurePrivateNetworkRequests',
'--disable-site-isolation-trials'
],
defaultViewport: null,
ignoreHTTPSErrors: true
}
Sometimes I have an issue:
This site can’t be reached. The webpage at https://some.site.com might be temporarily down or it may have moved permanently to a new web address.
ERR_SSL_BAD_RECORD_MAC_ALERT
when I try page.goto('https://some.site.com').
const page = await browser.newPage();
if (proxy && proxy.login && proxy.pass) {
await page.authenticate({
username: proxy.login,
password: proxy.pass,
});
}
try {
console.log('POINT 13');
await page.goto(films[i].url);
console.log('POINT 14');
return;
} catch (e) {
console.log('POINT 15');
return;
}
I see POINT 13 in my console, but neither POINT 14 nor POINT 15. The script like slept freezes between points 13 and 14, on page.goto()...
I have tried to change timeout for page.goto() function but it's not work.
so I have a puppeteer script to watch TikTok live streams and when I run it locally it works as expected, but in Ubuntu 20.04 LTS Server the page loads for the live stream, but the live stream never starts and it requires me to log in, which doesn't have locally either. Any ideas to bypass that detection?
Settings
const puppeteer = require("puppeteer-extra");
const { Cluster } = require("puppeteer-cluster");
// Use stealth plugin to bypass bot detection
const StealthPlugin = require("puppeteer-extra-plugin-stealth");
const AnonymizeUA = require("puppeteer-extra-plugin-anonymize-ua");
const AdblockerPlugin = require('puppeteer-extra-plugin-adblocker');
puppeteer.use(StealthPlugin());
puppeteer.use(AnonymizeUA());
puppeteer.use(AdblockerPlugin({ blockTrackers: true }));
(async () => {
const cluster = await Cluster.launch({
concurrency: Cluster.CONCURRENCY_CONTEXT,
maxConcurrency: 60000,
timeout: 86400000,
puppeteer: puppeteer,
retryLimit: 10,
retryDelay: 1000,
puppeteerOptions: {
headless: true,
timeout: 120000, //360000
args: [
"--start-maximized",
"--no-sandbox",
"--disable-setuid-sandbox",
"--disable-dev-shm-usage",
"--disable-accelerated-2d-canvas",
"--no-first-run",
"--no-zygote",
"--disable-gpu",
],
executablePath: "/snap/bin/chromium",
defaultViewport: null,
},
});
Even when I install GUI on the machine, and visit the live stream manually I still cant view it, so it has something to do with the server getting detected as a server maybe?
Thanks a lot!
I am using an Ubuntu server 18.04.5 LTS and Puppeteer 10.0.0. My Problem is that the browser.newPage() function never resolves. So basicly in the console it alsways loggs Start but never 1 nor 2. I have tried a different puppeteer version or puppeteer-core with my own chromium version. I even installed an VM on my Pc and it works there but not on my Server.
var puppeteer = require('puppeteer')
var adresse = "https://www.google.de/"
async function test() {
try {
const browser = await puppeteer.launch({
"headless": true,
"args": [
'--disable-setuid-sandbox',
'--no-sandbox',
'--disable-gpu',
]
})
console.log("Start")
const page = await browser.newPage()
console.log("1")
await page.goto(adresse)
console.log("2")
console.log(page)
} catch (error) {
console.log(error)
}
}
test()
I have a Firebase function to create a PDF file. Lately, it times out due to a "Chrome revision"? Neither do I understand the error message, nor do I understand what is wrong. The function works, when I deploy it locally under MacOS.
TimeoutError: Timed out after 30000 ms while trying to connect to the browser! Only Chrome at revision r818858 is guaranteed to work.
at Timeout.onTimeout (/workspace/node_modules/puppeteer/lib/cjs/puppeteer/node/BrowserRunner.js:204:20)
at listOnTimeout (internal/timers.js:549:17)
at processTimers (internal/timers.js:492:7)
The function:
const puppeteer = require('puppeteer');
const createPDF = async (html, outputPath) => {
let pdf;
try {
const browser = await puppeteer.launch({
args: ['--no-sandbox']
});
const page = await browser.newPage();
await page.emulateMediaType('screen');
await page.setContent(html, {
waitUntil: 'networkidle0'
});
pdf = await page.pdf({
// path: outputPath,
format: 'A4',
printBackground: true,
margin: {
top: "50px",
bottom: "50px"
}
});
await browser.close();
} catch (e) {
console.error(e);
}
return pdf;
};
TimeoutError: Timed out after 30000 ms while trying to connect to the browser!
The aforementioned error is coming from the fact that as mentioned in the documentation:
When you install Puppeteer, it downloads a recent version of Chromium
Everytime you're executing Puppeteer you're running a Chromium in the backend to which Puppeteer will try to connect, hence when it can't connect to the browser this errors raises.
After doing multiple test I was able to execute the Cloud Function by adding the parameter headless on the launch option, since the documentation mentions that it should be true by default I don't quite understand why setting it manually allows the Cloud Function to finish correctly.
At the beginning I was trying with the timeout set to 0 to disable the error due to timeout, however it seems that it's not required, since by only adding headless it finished correctly, but if you find the same problem with the timeouts you can add it.
At the end my code looks like this:
const createPDF = async (html, outputPath) => {
let pdf;
try {
const browser = await puppeteer.launch({
args: ['--no-sandbox'],
headless: true,
timeout: 0
});
const page = await browser.newPage();
await page.emulateMediaType('screen');
await page.setContent(html, {
waitUntil: 'networkidle0'
});
pdf = await page.pdf({
// path: outputPath,
format: 'A4',
printBackground: true,
margin: {
top: "50px",
bottom: "50px"
}
});
await browser.close();
console.log("Download finished"); //Added this to debug that it finishes correctly
} catch (e) {
console.error(e);
}
return pdf;
};
Problem: Using puppeteer to get the screengrab of a website. Works fine on dev machine but throws below exception when deployed to Azure Functions on the cloud.
Environment: on Azure(Node 12, Linux, Consumption plan), Function triggered using service bus topic.
Error:

I followed the recommendations that are on puppeteer troubleshoot document but still having the same issue.
Things I tried for lunch setting
let browser = await puppeteer.launch({ ignoreDefaultArgs: ['--disable-extensions'] });
let browser = await puppeteer.launch({ headless: true, args: ['--no-sandbox', '--disable-setuid-sandbox'] });
let browser = await puppeteer.launch({ headless: true });
let browser = await puppeteer.launch({ args: ['--no-sandbox', '--disable-setuid-sandbox'] });
None of the above worked. They all throw the same error.
I checked FTPing into the function and the chrome file puppeteer is looking for, exists.
Thanks in advance.
Azure has the necessary dependencies for running headless Chromium in the Linux Consumption plan. So we can use the package puppeteer in Azure function. But we need to deploy the app using remote build. For more details, please refer to the Azure feedback and the blog.
For example
Create Azure function app
Create Azure function project
a. Install package
npm install puppeteer
b. function.json
{
"bindings": [
{
"name": "mySbMsg",
"type": "serviceBusTrigger",
"direction": "in",
"topicName": "bowman1012",
"subscriptionName": "test",
"connection": "bowman1012_SERVICEBUS"
},
{
"type": "blob",
"direction": "out",
"name": "outputBlob",
"path": "outcontainer/{rand-guid}.png",
"connection": "AzureWebJobsStorage"
}
]
}
c. code
const puppeteer = require("puppeteer");
module.exports = async function (context, mySbMsg) {
context.log(
"JavaScript ServiceBus topic trigger function processed message",
mySbMsg
);
const browser = await puppeteer.launch({ headless: true });
const page = await browser.newPage();
await page.goto("https://google.com/");
const screenshotBuffer = await page.screenshot({ fullPage: true });
await browser.close();
context.bindings.outputBlob = screenshotBuffer;
};
Add .funcignore file in the root project folder
*.js.map
*.ts
.git*
.vscode
local.settings.json
test
tsconfig.json
node_modules
Deploy to Azure
func azure functionapp publish $appName --build remote
Test
Update
Since you use typescript to create Azure function, we need to update .funcignore as the following
*.js.map
.git*
.vscode
local.settings.json
test
node_modules
For example
My function code index.ts
import { AzureFunction, Context } from "#azure/functions";
import { ServiceBusMessage } from "#azure/service-bus";
import puppeteer from "puppeteer";
import { BlobServiceClient } from "#azure/storage-blob";
const serviceBusTopicTrigger: AzureFunction = async function (
context: Context,
mySbMsg: ServiceBusMessage
): Promise<void> {
try {
const promotionId = context.bindingData.userProperties.promotionId;
context.log(
"Player Screen Grabber ServiceBus topic trigger function processing message started",
promotionId
);
const playerURL = "https://www.google.com/";
let browser = await puppeteer.launch({ headless: true });
let page = await browser.newPage();
await page.goto(playerURL, { waitUntil: "networkidle2" });
await page.setViewport({ width: 1920, height: 1080 });
const screenshotBuffer = await page.screenshot({
encoding: "binary",
});
await page.close();
await browser.close();
// the storage account connection string
const constr = process.env["AzureWebJobsStorage"] + "";
const blobserviceClient = BlobServiceClient.fromConnectionString(constr);
const containerClient = blobserviceClient.getContainerClient(
"outcontainer"
);
const blob = containerClient.getBlockBlobClient(`${promotionId}.png`);
await blob.uploadData(screenshotBuffer);
context.log(
"Player Screen Grabber ServiceBus topic trigger function processing message ended",
promotionId
);
} catch (error) {
throw error;
}
};
export default serviceBusTopicTrigger;
Deploy to Azure
func azure functionapp publish $appName --build remote
Test
My service bus message
