"Error forwarding the new session new session request for webdriver should contain a location header with the session" When using PhantomJS with selenium grid in RemoteWebDriver mode

[seaders]

I start a selenium grid hub with it's default startup command,

java -jar selenium-server-standalone-2.33.0.jar -role hub

And I start up PhantomJS in it's webdriver mode, on the same machine, like,

phantomjs --webdriver=8080 --webdriver-selenium-grid-hub=http://127.0.0.1:4444

When PhantomJS starts up, I get nothing but "All 'OK'" messages,

[INFO  - 2013-09-09T18:10:38.849Z] GhostDriver - Main - running on port 8080
[INFO  - 2013-09-09T18:10:38.850Z] GhostDriver - Main - registering to Selenium HUB 'http://127.0.0.1:4444' using '127.0.0.1:8080'
[INFO  - 2013-09-09T18:11:47.164Z] HUB Register - register - Registered with grid hub: http://127.0.0.1:4444/ (ok)

But if I try to use that browser, with

driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub',
                          desired_capabilities=DesiredCapabilities.PHANTOMJS)

Looking at the output from the PhantomJS executable,

[INFO  - 2013-09-09T18:17:12.531Z] Session [0c5c9500-197c-11e3-8eed-b3b7a73965aa] - _decorateNewWindow - page.settings: {"XSSAuditingEnabled":false,"javascriptCanCloseWindows":true,"javascriptCanOpenWindows":true,"javascriptEnabled":true,"loadImages":true,"localToRemoteUrlAccessEnabled":false,"userAgent":"Mozilla/5.0 (Macintosh; Intel Mac OS X) AppleWebKit/534.34 (KHTML, like Gecko) PhantomJS/1.9.2 Safari/534.34","webSecurityEnabled":true}

Everything seems to be fine, but the code crashes :/ I get a huge error stacktrace, mainly down to,

selenium.common.exceptions.WebDriverException: Message: u'Error forwarding the new session new session request for webdriver should contain a location header with the session.'

And if you check the output of the grid hub,

INFO: Trying to create a new session on test slot {seleniumProtocol=WebDriver, browserName=phantomjs, maxInstances=1}
INFO: Available nodes: [host :http://127.0.0.1:8080 time out : 300000]

There also seems to be an issue. It seems like, for whatever reason, the grid hub doesn't get any information back from the PhantomJS executable, even though it seems like it is processing things correctly.

For testing, I also have a regular selenium node running, on the same machine, with the command

java -jar selenium-server-standalone-2.33.0.jar -role node

and if I start up a Firefox RemoteWebDriver session (in Python), with

driver = webdriver.Remote(command_executor='http://127.0.0.1:4444/wd/hub',
                          desired_capabilities=DesiredCapabilities.FIREFOX)

all is fine.

It looks like everything is set up correctly, I'm keeping things as 'vanilla' and close to what the docs say as possible, but just can't get over the fence here.

The exact same error happens when trying in Java, too

WebDriver driver = new RemoteWebDriver(DesiredCapabilities.phantomjs());

And my versions are 1.9.2 for PhantomJS and obviously 2.33.0 for selenium.

I am also seeing this. It does not occur with phantomjs 1.9.1. I imagine this is something introduced in the new ghostdriver code.

There is question up on stack overflow describing this exact issue here:

[jessesanford]

This seems to be solved by updating to the 2.35.0 selenium jar. You can get it here:

seeing this problem consistently with phantom 1.9.2 with selenium 2.35.0

Maybe not phantomJs related, but I have the same problem when connecting from Behat Selenium2Driver. In my case problem was in diverged versions of Selenium Node and Selenium Grid (node had 2.37 and grid had 2.33)

After updating version on Selenium Grid server everything works fine.

Due to our very limited maintenance capacity, we need to prioritize our development focus on other tasks. Therefore, this issue will be automatically closed (see #15395 for more details). In the future, if we see the need to attend to this issue again, then it will be reopened. Thank you for your contribution!
