Cannot read property '_set_canSkip' of undefined

Hi there. I installed the component using the bower install -S Zecat/paper-stepper#v2.0-beta.5 command but am not able to load the component on my page. I am getting the following trace:

Uncaught TypeError: Cannot read property '_set_canSkip' of undefined
    at HTMLElement._forwardCanSkip (my-stepper.html:5)
    at Object.D [as fn] (my-app.html:1)
    at o (my-app.html:1)

    at HTMLElement.ready (my-app.html:1)
    at HTMLElement.ready (my-app.html:1)
    at HTMLElement.ready (my-app.html:1)

I also included all of the imports shown in the demo but am getting the same error above.

Any help would be appreciated.

by using the 2.0 version under development it resolves this error, but this version is not yet stable as there are many css / styling issues "paper-stepper": "Zecat/paper-stepper#hybrid-modular-prototype"
