t.classList is undefined (sidebar.js:335:12)

After replacing

https://unpkg.com/@coreui/coreui/dist/js/coreui.min.js (v4)
by
https://unpkg.com/@coreui/coreui@3.0.0/dist/js/coreui.min.js (v3)

since i been using version 3 and not version 4
the sidebar dropdown is broken, i get this error below

Uncaught TypeError: t.classList is undefined
sidebar.js:335:12

I think its a versioning problem, anyone knows which v3 is currently working, thank you

fixed by using v3.4.0 instead
https://unpkg.com/@coreui/coreui@3.4.0/dist/js/coreui.min.js (v3.4.0)
