File Upload - Invalid argument supplied for foreach()

[ssfinney]

I'm using Codeception with the Facebook WebDriver module, Selenium 2, and PhantomJS on a Jenkins server that runs builds for me. The errors only occur on the Jenkins server (an Ubuntu box), not on my local Mac OS X machine.

I'm getting Invalid argument supplied for foreach(). Here's the stack trace:

#1  /var/lib/jenkins/workspace/project-name-feature__/vendor/facebook/webdriver/lib/WebDriverKeys.php:104
#2  /var/lib/jenkins/workspace/project-name-feature__/vendor/facebook/webdriver/lib/remote/RemoteWebElement.php:266
#3  /var/lib/jenkins/workspace/project-name-feature__/app/tests/acceptance/AcceptanceTester.php:1427
#4  /var/lib/jenkins/workspace/project-name-feature__/app/tests/acceptance/FooBarCest.php:54

I'm using the attachFile method in Codeception, which simply passes a CSS selector and a file path.

I've traced this back as far as it will go. The problem originates when the WebDriver sends the "sendFile" command inside webdriver/lib/remote/HttpCommandExecutor.php , which sends a POST through curl to /session/<session_id>/file, but the response returns with a value and session_id of null.

The null value gets passed back up to the upload method in webdriver/lib/remote/RemoteWebElement.php. Those values get passed back to the sendKeys method in the same file, which calls WebDriverKeys::encode. In the encode method, the foreach fails because of null values.

I've been chasing this bug for days. Do you have any ideas?

Here's the JSON response of the curl POST.

I have the same issue, also on ubuntu. I've only tried using PhantonJS.

I am looking. It would be very helpful If there is a way for reproducing. The HTTP code is 405 Method Not Allowed.

whhone if I get spare time I will try to reproduce, I'm using Webdriver via Codeception.

phantomjs version 1.9.7 x86

Is there any update on this, or can I provide any more information for you?

[alvaxet]

I'm having the same issue. If I can help somehow to fix, please let me know

Closing this as it is over 6 months old. If it is still an issue, please create a new issue with as much current reproduction information as possible. Thanks.

With the newest versions of Selenium, PhantomJS, and the webdriver module in Codeception, this issue seems to have been fixed along the way.
