TypeError: Cannot read property 'querySelectorAll' of undefined

[illycz]

I'm using AOS library, where in the code is: var e=document.querySelectorAll("[data-aos]");.
In HTML I have element with data-aos attribute, but in console I get: [TypeError: Cannot read property 'querySelectorAll' of undefined]

Any suggestions?

Thanks
