Selenium::Firefox ... You need to specify a browser or driver

[davewood]

things keep changing and breaking my working setup and im trying to figure out the most recent change.

this is my selenium service, running in a container (image: selenium/standalone-firefox)

epplication-selenium | Selenium Grid Standalone configuration:
epplication-selenium | [network]
epplication-selenium | relax-checks = true
epplication-selenium |
epplication-selenium | [node]
epplication-selenium | session-timeout = "300"
epplication-selenium | override-max-sessions = false
epplication-selenium | detect-drivers = false
epplication-selenium | drain-after-session-count = 0
epplication-selenium | max-sessions = 1
epplication-selenium |
epplication-selenium | [[node.driver-configuration]]
epplication-selenium | display-name = "firefox"
epplication-selenium | stereotype = '{"browserName": "firefox", "browserVersion": "117.0", "platformName": "Linux"}'
epplication-selenium | max-sessions = 1
epplication-selenium |
epplication-selenium | Starting Selenium Grid Standalone...

...

when i try to connect

      my $driver = Selenium::Firefox->new(
          remote_server_addr => $conf{host},
          port => $conf{port},
      );

i see this error

it works with an older docker-selenium version, buit not with latest.

docker-compose.yml
image: selenium/standalone-firefox:114.0-geckodriver-0.33-grid-4.10.0-20230614

and im a bit confused because the README says (https://github.com/teodesian/Selenium-Remote-Driver/blob/master/README.md)

This module is also not ready for SeleniumHQ's 4.0 series JAR. For compatibility with that, try our next generation selenium client: Selenium::Client

Geckodriver, for a long time had not removed the code to connect via earlier selenium connection strings. That's why it still worked. If that has changed, then things would indeed break the same way they do for the selenium 4 Jar.

nevertheless this probably means there are no viable workarounds to use this module any longer. I suppose that finally moves this up to the top of my list.
