Why am I getting this WebDriver exception in Chrome and not in Firefox

Question

Here is the error

WebDriverException: Message: "findElement execution failed;\\n Property \'Error\' of object [object DOMWindow] is not a function"

I run:

LoginPage.authenticate(self, self.admin_user) 

This works fine, logs me in OK, but as soon as I try to find an element on the next page using the chrome driver:

self.driver.find_element_by_id('Menu_LogInOut')

I get the above error. It doesn't error out in Firefox.

Has anyone else run into this? What is going on? How do I get around it?

Answer 1

We had inadvertently overwritten window.Error in our application. Thank you webdriver for pointing this out.

The fix is to not do this, something like window.Error_These_arent_the_droids_youre_looking_for.
