TypeError: 'undefined' is not an object (evaluating 'rect.top')

[bettysteger]

i am getting the following error

  Failure/Error: click_button "Sign up"
    Capybara::Poltergeist::JavascriptError:
      One or more errors were raised in the Javascript code on the page:

      TypeError: 'undefined' is not an object (evaluating 'rect.top')

the problem was that i have required something in a css file that didn't exist: *= require_tree ./landing i got an error when going to localhost:3000: require_tree argument must be a directory (Sprockets::ArgumentError)

so i have solved this problem by added the right directory... but i got in the wrong direction with that error message!

I have the same issue, but only on Travis CI with Ruby Enterprise Edition:

http://travis-ci.org/#!/magiclabs/alchemy_cms/jobs/2123243/L1069

The method that causes this error is always the same:

def login_into_alchemy
  visit '/alchemy/admin/login'
  fill_in('alchemy_user_session_login', :with => 'jdoe')
  fill_in('alchemy_user_session_password', :with => 's3cr3t')
  click_on('Login')
end

So nothing fancy in here. You can visit the page yourself: http://demo.alchemy-cms.com/admin/login

The strange thing about it is, that on my local machine all tests pass, even with REE.

Just put a sleep 1 between visit and fill_in:

http://travis-ci.org/#!/magiclabs/alchemy_cms/jobs/2123618

As you can see this does not help. So no timing issue. What else?

And this build contains a debug log:

I have the same issue. On Mac it's all good. Just not on a ubuntu box. :(

I have this issue on my mac.

$ phantomjs -v   
1.6.1
$ which phantomjs
/usr/local/bin/phantomjs

In my features/support/env.rb

require 'capybara/poltergeist'
Capybara.register_driver :poltergeist do |app|
  Capybara::Poltergeist::Driver.new(app, 
    timeout: 5, debug: true, phantomjs: "/usr/local/bin/phantomjs")
end
Capybara.javascript_driver = :poltergeist

@tvdeyen @ywen @drnic hi guys, please see the above commit I just added. I'm not sure if this will actually solve your problems, but it will at least prevent the JS throwing a TypeError. It also means that the Capybara retry mechanism will work properly. Please give it a try and let me know how it goes?

[ywen]

Just make sure this is in the master branch correct? I will give it a try maybe tomorrow. Thanks!

[jonleighton]

Yes, master branch.

[ywen]

Yay, the error is gone! Thanks

I'm having this problem on master. The test passes when using the Chrome driver, but with Poltergeist it fails with:

One or more errors were raised in the Javascript code on the page:

@andyw8 from that stack trace, it doesn't look like you're using master.

[andyw8]

Ah, my mistake. I'd specified the ref in the Gemfile but not the git repo so the ref was being ignored. All passing now.

[nchandratre]

@andyw8 I am facing same problem. Test fails with Poltergeist. How to resolve?

[jonleighton]

@nchandratre please post a new issue with details about your problem
