unknown command now that chrome has updated when using Watir-webdriver

Last week chrome auto updated to 29.0.1547.57 and they completely messed
up all of our regression tests. So I downloaded and updated my
chromedriver to v2.2. Now the test will at least run but almost all fail
with this error.
unexpected response, code=404, content-type="text/plain"
unknown command: session/f82f867596e3c001854423097f341bfe/element/name
(Selenium::WebDriver::Error::WebDriverError)
The real confusing part is that it works on my local when I start the test
through rubymine, but when the test run on the server started by Jenkins
they all fail.
They seem to be failing on wait_until_present when we wait for our ajax
popups to load, and also on .exists?. For example:
if @browser.a(:id, 'hn_modal_close').exists?
@browser.a(:class, 'blackText noTextDecoration').click
else
@browser.link(:href, /shopping_cart.cfm/).click
end
It errors on the first line of the if statement, but this exact code works
fine if I run it with irb.
Does anybody have any ideas why this is happening?
