Hi there!

I use `webdriver` package for test automation with PhantomJS. And I need to click some button, but not with a `click` function, but with a native JS. I see a special function for such a task, `executeJS`, in the module `Test.WebDriver.Commands`. So this is my code:

    ...
    button <- findElement . ById $ "clearCart"
    info <- elemInfo button
    executeJS [JSArg info] "arguments[0].click();"
    ...

But I got a runtime error:

BadJSON "when expecting a (), encountered Null instead"

How can I fix it?
