[🐛 Bug]: Session unable to start for Selenium 4.11.0 due to permission error

[jamesmortensen]

What happened?

In the logs, we can see tests failing when attempting to test Seleniarm images using Selenium 4.11.0. The full logs can be found here:

https://app.circleci.com/pipelines/github/seleniumhq-community/docker-seleniarm/368/workflows/bcace299-db41-4695-8f7c-cfc374605b2a/jobs/1398

The part that sticks out to me is the complaints about permission issues and unexpected word:

selenium.common.exceptions.SessionNotCreatedException: Message: Could not start a new session. Could not start a new session. Unable to obtain: Capabilities {browserName: chrome, browserVersion: 116.0, goog:chromeOptions: {args: [], extensions: []}, pageLoadStrategy: normal, se:noVncPort: 7900, se:vncEnabled: true}, error Command failed with code: 2, executed: [/tmp/selenium-manager67305284127211587224812580076201/selenium-manager, --browser, chrome, --output, json, --browser-version, 116.0]

Command used to start Selenium Grid with Docker

I took a moment to document the issue preventing moving forward to Selenium 4.11.0. I am in the process of moving back to the USA, so if there's anyone who would like to help with this issue, that would be awesome!

There is a permissions issue in 4.11.0 when using Selenium Manager in Linux. This is solved for 4.12.0.

However, I disabled Selenium Manager for Docker Selenium: https://github.com/SeleniumHQ/docker-selenium/commit/b5cec1c8de56823a8fbb227cfc048882bc12238e. Maybe you can do the same?

I'm not sure if this is related, but wanted to let you know I had problems using the latest seleniarm-chromium image since the update a couple days ago. Specifically, when I ran a driver.get('https://google.com'), I would get the error message: selenium.common.exceptions.NoSuchWindowException: Message: no such window: target window already closed from unknown error: web view not found Once I reverted to a previous version (standalone-chromium:4.10.0-20230615), things worked again. Running on Linux too.

Hi @diemol I brought in your commit that puts SM into offline mode https://github.com/seleniumhq-community/docker-seleniarm/commit/b5cec1c8de56823a8fbb227cfc048882bc12238e and I've updated to Selenium 4.12.1. The tests are still failing https://app.circleci.com/pipelines/github/seleniumhq-community/docker-seleniarm/373/workflows/4b1a759e-7831-4858-9d3c-765a5e8dc723/jobs/1438

Did the names of the browsers change from chrome to google-chrome? I also still see this in the stack trace:

/tmp/selenium-manager1020021369244423436900371086586/selenium-manager: 1: Syntax error: "(" unexpected

Please let me know if you might know what this is about. Thank you!

Just made an attempt to run a quick test using Selenium 4.12.1 and Chromium. Here's what I get:

SessionNotCreatedError: Could not start a new session. Error while creating session with the driver service. Stopping driver service: Could not start a new session. Response code 500. Message: session not created: Chrome failed to start: exited normally.
  (session not created: DevToolsActivePort file doesn't exist)
  (The process started from chrome location /home/seluser/.cache/selenium/chrome/linux64/117.0.5938.92/chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

}

It looks like the system is trying to use Chrome for Testing, as it's looking for the Chrome binary inside the /home/seluser folder. Instead, it should be looking for Chromium at /usr/bin/chromium. If I can fix this, or if someone knows what might be happening here, we can perhaps get docker-seleniarm up and running fully again on the latest Selenium version.

I'm in the middle of a major life change and am the only maintainer, so I appreciate everyone's patience and appreciate any help others can bring to the table.

Fixed by #55 Thanks for the assist @fhoeben and @diemol
