Uncaught TypeError: Cannot read property 'setAttribute' of undefined

[Alexis-Dia]

Hi! I just installed ember-scrollable using npm i [email protected] --save and included my code into:
{{#ember-scrollable onScrolledToBottom=(action 'log' 'Bottom reached!')}}
...TABLE CONTENT
{{/ember-scrollable}}

and got problem:
ember.debug.js:2532 Uncaught TypeError: Cannot read property 'setAttribute' of undefined
at DOMHelper.prototype.setAttribute (ember.debug.js:2532)

Can you please explain me, what the problem is?
