Status code was: 64 Meaning

[Michael Rosenhahn]

Hello,

  I am recently hitting the following error with Selenium and I am trying to determine the cause of the error. 

selenium.common.exceptions.WebDriverException: Message: Service /usr/local/bin/geckodriver unexpectedly exited. Status code was: 64

What are the common causes for Status code 64?

Also is there a link to the definition of the status codes?

The below two links seem to suggest that it was because the binary was invoked in an incorrect way

https://github.com/mozilla/geckodriver/issues/1460

https://www.freebsd.org/cgi/man.cgi?query=sysexits&apropos=0&sektion=0&manpath=FreeBSD%204.3-RELEASE&format=html

The common reasons for that could be that you perhaps have an out of sync situation between your geckodriver and your selenium version?

It would be good if you could include the below information:

1. What version of Selenium are you using?

2. What version of geckodriver are you running?

3. What version of Firefox are you using?

Thanks & Regards

We started running into this issue when we upgraded from Python 2 to Python 3.8 and are currently working on fixing all the conversion issues.. Before the upgrade the version of Firefox was locked at 38.6.1ESR

• Python version  3.8.6
• Selenium version 4.0.0
• Geckodriver version  v0.26.0
• Firefox Version 38.6.1ESR

Hello guys,

I am also facing the same issue,

selenium.common.exceptions.WebDriverException: Message: Service /usr/bin/geckodriver unexpectedly exited. Status code was: 64

Python 3.7.12

selenium 4.1.0

Mozilla Firefox 88.0

geckodriver 0.29.1

Python firefiox and geckodriver driver versions were locked in the docker image, but selenium was not, so i am assuming selenium 4.1.0 is the issue.
Any thoughts?

Hi,

The latest GeckoDriver is 0.30.0, so you will need to update to that version.

Cheers,

Adrian.

Just to add to that, have a look at the supported platforms page here https://firefox-source-docs.mozilla.org/testing/geckodriver/Support.html

You can see for GeockoDriver 0.30 is required for FireFox 78 ESR and above.

Otherwise when you run your tests they quit on start up.

Cheers,

Adrian.
