Cannot get page to scroll via js

Trying to simply make a page auto scroll down, just going off the standard Vue.js Simple template, just added a few

s of text to fill the page, but no matter what container i target or what method of trying to make the page scroll, nothing works. I can’t get the page to scroll via js at all.

$$(‘body’).scrollTop(10000, 400); //nothing
window.scrollBy(, 500); //nothing

$$('.page-content').scrollTop(1000, 400);
