WebDriverException: Message: Service geckodriver unexpectedly exited. Status code was: 64 error using Selenium Geckodriver Firefox in FreeBSD jail

  1. How to solve WebDriverException: Message: Service geckodriver unexpectedly exited. Status code was: 64 error using Selenium Geckodriver Firefox in FreeBSD jail

    This error message…
    selenium.common.exceptions.WebDriverException: Message: Service geckodriver unexpectedly exited. Status code was: 64
    and the GeckoDriver log…
    geckodriver: error: Found argument '--websocket-port' which wasn't expected, orisn't valid in this context
    …implies that the GeckoDriver was unable to initiate/spawn a new Browsing Context i.e. firefox session.

    Your main issue is the incompatibility between the version of the binaries you are using as follows:
    Your Selenium Client version is 4.1.0.
    But your GeckoDriver version is 0.26.0.
    As @ernstki mentions in their comment:
    You are running a geckodriver older than 0.30.0, and it is missing the --websocket-port option, which newer/new-ish versions of Selenium seem to depend on.
    To put it in simple words, till the previous GeckoDriver release of v0.29.0 the --websocket-port option wasn't in use, which is now mandatory with Selenium v4.0.1.
    Further @whimboo also confirmed in his comment:
    As it has been manifested the problem here is not geckodriver but Selenium. As such you should create an issue on the Selenium repository instead, so that an option could be added to not always pass the –websocket-port argument. If that request gets denied you will have to use older releases of Selenium if testing with older geckodriver releases is really needed.

Solution

Ensure that:

  • Selenium is upgraded to current levels Version 4.1.0.
  • GeckoDriver is upgraded to GeckoDriver v0.30.0 level.
  • Firefox is upgraded to current Firefox v96.0.2 levels.

FreeBSD versions

Incase you are using FreeBSD versions where the GeckoDriver versions are older, in those cases you have to downgrade Selenium to v3.x levels.

Commands (courtesy: Kurtibert):

  • Uninstall Selenium:

    pip3 uninstall selenium;
    
  • Install Selenium:

    pip3 install 'selenium<4.0.0'
