问题
I use protractor to test Angular2 app. It was working fine and I think I didn't change nothing in conf but now it ends up with this:
...
super(opt_error);
^
SessionNotCreatedError: session not created exception
from unknown error: Runtime.executionContextCreated has invalid 'context': {"auxData":{"frameId":"4012.1","isDefault":true},"id":1,"name":"","origin":"://"}
(Session info: chrome=54.0.2840.71)
(Driver info: chromedriver=2.21.371459
...
I work on a Mac OSX 10.11.4, Chrome 54.0.2840.71.
Any suggestion? Thanks
--- EDIT 26/10
Since it depends on each one settings it looks like theres no absolute answer to this. The main idea is to update protractor/ chromedriver / webdriver-manager accordingly.
Saying that i now face another problem : every basic test i do, including ( for instance ) a browser.get() is failing with :
Error: Timeout - Async callback was not invoked within timeout specified by jasmine.DEFAULT_TIMEOUT_INTERVAL
I don't know if it's an isolated case and if it fits here (I use jasmine2 as framework) so I start another question here
回答1:
I installed ChromeDriver v2.24 and stored it in: /usr/local/Cellar/chromedriver/2.24/bin and it fixed the error for me.
回答2:
As mentioned by others, looks like it is a problem with the chromedriver installed in the system with the new version of chrome. For mac, I updated the chromedriver using 'chromedriver-update' and this fixed it.
回答3:
I had a similar problem and solver it by forcing chromedriver 2.24 to install by manually removing webdriver-manager
delete the folder rm -rf /usr/local/lib/node_modules/webdriver-manager/
reinstall webdriver
npm install -g webdriver-manager

I updated the selenium-standalone to the latest version 5.8.0 (from 5.1.0). It will install the newer version of chrome webdriver(2.25), instead of install chrome driver2.21. This solved the issue on my end.(no connection, session exception)
回答5:
If even after updating the webdriver to 2.25, the error is still occurring and if you are using the terminal app this should help :
I managed to fix the issue by unchecking “Set locale environment variables on startup” checkbox in advanced terminal app settings. Or try to launch your test with this prefix :
LC_NUMERIC=”en_US.UTF-8″ npm test
