toolkit: Including toolkit plugin throws error

I am using the toolkit with Alpine 3.10.2 like this

import Alpine from 'alpinejs'
import Toolkit from '@alpine-collective/toolkit'
import GLightbox from 'glightbox';
import $ from 'jquery';
import 'slick-carousel';

Alpine.plugin(Toolkit)
Alpine.start()

but I am getting an error on the console saying

Uncaught TypeError: e is not a function

This happens with yarn run production.

When running yarn run dev I get this error

which leads me to this place

Any idea what is wrong there?
