QUESTION
So i have this nodejs that was originaly used as api to crawl data using puppeteer from a website based on a schedule, now to check if there is a schedule i used a function that link to a model query and check if there are any schedule at the moment.
It seems to work and i get the data, but when i was crawling the second article and the next there is always this error UnhandledPromiseRejectionWarning: Error: Request is already handled!
and followed by UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch().
and it seems to take a lot of resource from the cpu and memory.
So my question is, is there any blocking in my code or anything that could have done better.
this is my server.js

Answered 2021-Jun-05 at 16:26I figured it out, i just used puppeteer cluster.
QUESTION
I'm using Puppeteer.js to crawl some URL. I'm using the default Chromium browser of Puppeteer.
All is working well, but the problem is, that when I run the crawling script, and doing other things in the background and the focus is no longer on the Chromium browser of Puppeteer, it's not working: waiting for elements way too long, and abort operations, or in other words: puppeteer is paused (or freeze).
P.S, I'm also using puppeteer-extra and puppeteer-extra-plugin-stealth NPM packages for advance options.
Here is how I create the browser and the page:

Answered 2021-Apr-24 at 18:46My issue was solved when I updated to the latest puppeteer version (9.0.0).

I'm trying to create this lambda function in AWS using Amplify however when I try to launch the chromium the lambda function does not return any value and the function end up timing up:

QUESTION
I'm trying to run a simple Azure Function that would enter page and generate a PDF depending on what is visible in a browser.
I created a NodeJS 12 Azure Function with Linux Consumption Plan (B1). I set PLAYWRIGHT_BROWSERS_PATH
to 0
.
Function code looks like this:
...ANSWER
Answered 2020-Sep-18 at 17:17I played with your example for a while and I got the same errors. These are the things I found that made my example work:
It must be Linux. I know that you mentioned that you picked a Linux plan. But I found that in VS Code that part is hidden, and on the Web the default is Windows. This is important because only the Linux plan runs npm install
on the server.
Make sure that you are building on the server. You can find this option in the VS Code Settings:
Make sure you set the environment variable PLAYWRIGHT_BROWSERS_PATH
, before making the publish.
QUESTION
Tell us about your environment:
Puppeteer version: 1.11.0 Platform / OS version: Windows 10 1709 URLs (if applicable): Node.js version: 10.x.x as well as 11.4.0 What steps will reproduce the problem?
const puppeteer = require("puppeteer"); puppeteer.launch(); What is the expected result? A headless browser launching in the background and no console error.
What happens instead? chrome.exe is run without any command line switch, opening a non-headless window and eventually the tab also crashes, until it is killed by Puppeteer.
...ANSWER
Answered 2020-May-12 at 16:10I found this on github issues.
--disable-extensions is forbidden in my corporate environment.
That was stupid (the extensions it mandates are not security sensitive or protective or enforcing anything).
puppeteer.launch({ignoreDefaultArgs: ['--disable-extensions']}) fixes it

Answered 2020-May-04 at 01:52Found a solution, you need to play the media and open the file correctly, for simplicity I use "libvlc_media_new_path" in this example, if you are using "libvlc_media_new_location", remember to append "file:///" before the location and change to native separator.
QUESTION
Following the VLC macOSCompile wiki page. Using the single command build instructions. I'm running 10.14.6 with Xcode 11.3.1 commandline tools, developer signed, etc.
Important note -- my MacOSX.sdk file is located here: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk
All is good through build to create makefile, completes bootstrap and runs make. Then I get the following error -- how do I point VLC to the location where my MacOSX.sdk file is located?
IOW how do I set vlc's "contrib environment"?
Please note in the code snip below, that contrib sets the MacOSX.sdk file pointer to the WRONG location - how do I fix?
Do I need to edit something in the vlc source? Thanks. errors:

I have a C++ application that is crashing on startup for some Windows 7 users. I can't reproduce the error on my own machine, but used breakpad to generate a .dmp file, which shows that the code is crashing with "Illegal instruction" initializing a static std::vector array. What could this possibly mean?

is an AVX instruction. AVX is supported starting from Sandy Bridge (Intel Core 2-nd gen., introduced around 2011).
On an older CPU the instruction will trap with an Illegal Instruction error.
You should either recompile your app without AVX support and/or use __cpuid
to check the CPU capabilities, and delegate execution to the "slow" version, if needed.
QUESTION
I am running chrome driver over selenium on a ubuntu server. Behind a residential proxy network . Yet my selenium is being detected . Is there a way to make chrome driver and selenium 100% undetectable ?
I have been trying for so long I lost track of the many things I have done including:
- Trying different versions of chrome
- Adding several flags and removing some words from the chrome driver file.
- Running it behind a proxy (residential ones also) using incognito mode.
- Loading profiles.
- Random mouse movements.
- Randomising everything.
I am looking for a true version of selenium that is 100% undetectable . if that ever existed .or another automation way that is not detectable by bot trackers .
This is part of the starting of the browser
...ANSWER
Answered 2020-Jan-28 at 08:43The fact that selenium driven WebDriver gets detected doesn't depends on any specific Selenium, Chrome or ChromeDriver version. The Websites themselves can detect the network traffic and can identify the Browser Client i.e. Web Browser as WebDriver controled.
However some generic approaches to avoid getting detected while web-scraping are as follows:
- The first and foremost attribute a website can determine your script/program is through your monitor size. So it is recommended not to use the conventional Viewport.
- If you need to send multiple requests to a website, you need to keep on changing the user-agent on each request. You can find a detailed discussion in Way to change Google Chrome user agent in Selenium?
- To simulate human like behavior you may require to slow down the script execution even beyond WebDriverWait and expected_conditions inducing
time.sleep(secs)
. Here you can find a detailed discussion on How to sleep webdriver in python for milliseconds
@Antoine Vastel in his blog site Detecting Chrome Headless mentioned several approaches, which distinguish the Chrome browser from a headless Chrome browser.
User agent: The user agent attribute is commonly used to detect the OS as well as the browser of the user. With Chrome version 59 it has the following value:
QUESTION
The following comment in breakpad suggests that resetting the signal handler forces the signal to be rethrown. However, I wasn't able to find any documentation online that describes this behaviour.
Additionally, the comment here says once the signal handler returns, the signal will be rethrown. Is this also as a result of the signal handler being restored or reset to the default?
...ANSWER
Answered 2019-Nov-14 at 13:34suggests that resetting the signal handler forces the signal to be rethrown
says once the signal handler returns, the signal will be rethrown
Neither is true. However, I don't believe that's what the comments imply. The likely case is that it leaves the signal unprocessed in some cases. So the original problem that triggered the signal triggers the same signal again. Consider this example:
