WebDriverException: unknown error: Runtime.executionContextCreated has invalid ‘context’: while initializing Chrome browser

by

This error message…

org.openqa.selenium.WebDriverException: unknown error: Runtime.executionContextCreated has invalid 'context': {"auxData":{"frameId":"11895A1B77AC560388AA2919259E1422","isDefault":true},"id":1,"name":"","origin":"://"}

…implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.

Your main issue is the version compatibility between the binaries you are using as follows :

  • You are using chromedriver=2.8 which is pretty ancient.
  • You are using chrome=66.0
  • Release Notes of ChromeDriver v2.38 clearly mentions the following :

Supports Chrome v65-67

So there is a clear mismatch between ChromeDriver version (v2.8) and the Chrome Browser version (v66.0)

Solution

  • Upgrade ChromeDriver to current ChromeDriver v2.38 level.
  • Keep Chrome version at Chrome v66.x levels. (as per ChromeDriver v2.38 release notes)
  • Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
  • Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
  • If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
  • Take a System Reboot.
  • Execute your @Test.
  • Always invoke driver.quit() within tearDown(){} method to close & destroy the WebDriver and Web Client instances gracefully.
