1486620 - GeckoDriver + selenium gives error org.openqa.selenium.WebDriverException: Session [null] not available and is not among the last 1000 terminated sessions

Status: RESOLVED INCOMPLETE

(Testing :: geckodriver, defect)

Description

[seleniumfirefox18]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36

Steps to reproduce:

I was trying to run selenium tests using GeckoDriver (version 21) on firefox (version 61).
AS soon as I launch the tests it errors out saying session NULL not found.
The test completes successfully on selenium version 3.4.0 but it fails on selenium versions 3.9.0 and above.


Actual results:

org.openqa.selenium.WebDriverException: Session [null] not available and is not among the last 1000 terminated sessions

Usually we use https://github.com/mozilla/geckodriver/issues as issue tracker, but while you are already here let me request two things which are missing in your report:

1) Please provide a trace level log of geckodriver. See https://firefox-source-docs.mozilla.org/testing/geckodriver/geckodriver/TraceLogs.html in how to get one, and then add it as attachment it here.

2) Provide some minimal source code to reproduce the problem.

I don't know where this tracker is, so if you have more details please add a link to the issue.

Until then this is incomplete due to missing information.
