[Browserless Chrome] title

[FabioEight]

Hello,

Is it possible to execute a default script in browserless chrome at the addon startup? I have a NodeRed flow using Selenium to reach and interact with several webpages. Currently the webdriver is hosted on a secondary device in my network and I would like to move all to HAOS. Basically I just need to launch the browserless-chrome webdriver at every startup of the addon.

Thank you!

Hi, the option already exists. Any scripts in /config/browserless_chrome.sh will be executed at boot (the exact path for the script is described in the log)

[alexbelgium]

In a future version of my script, all scripts will be copied to /config/addons_autoscripts to centralise them. It will be done automatically so no action required on your side

Awesome, thanks for your reply. I'm having some issues already at the testing stage, I use the following code in browserless:

const webdriver = require('selenium-webdriver');
const fs = require('fs');

const chromeCapabilities = webdriver.Capabilities.chrome();
chromeCapabilities.set(
  'chromeOptions', {
    args: [
      '--headless',
      '--no-sandbox',
      '--whitelisted-ips=""'
      '--base-url /'  #same parameters used in my ssh script
    ],
  }
);

const driver = new webdriver.Builder()
  .forBrowser('chrome')
  .withCapabilities(chromeCapabilities)
  .usingServer('http://192.168.1.X:3000/webdriver') // my HAOS local IP
  .build();

From NodeRed I have this error while trying to opening a new session:

27 Dec 17:02:29 - [info] [open browser:FLOW] http://192.168.1.X:3000/ is reacheable by Node-red

27 Dec 17:03:20 - [error] [open browser:FLOW] Error: Incorrect HTTP header 'content-type', expected 'application/json'

Instead, from the browserless chrome logs I don't have any useful information:

It is also strange that the arguments provided by the browserless webgui are not shown in the logs..

This Addon is super simple shell around the official docker image. Have you checked on their repo if there is anything that could help? Looks like the error is Incorrect HTTP header 'content-type', expected 'application/json'

[FabioEight]

Yes, I tried the quick start steps but no luck. Will investigate further. By the way, this might not be the correct way to ask, but do you think it's possible to create an addon of chromedriver or any other Selenium based webdriver for this purpose? Thanks for your effort!
