Having exactly the same issue along with other messages:

EDIT: I figured that in my app in PDFData.vue -> function getPages(pdf, first, last), for value of variable pdf I am getting PDFDocumentLoadingTask and in this repo it is PDFDocumentProxy

Showing them here top to bottom from console:

This one is shown 2 times, and I figured that issue is in the ScrollingDocument.vue -> updateScrollBounds method, where code
const {scrollTop, clientHeight} = this.$el; is causing it cause this.$el is undefined.

Uncaught ReferenceError: window is not defined at pdf.worker.js:1

This is really bugging me for some time now, and I only copy/pasted source files from this repo to mine, and also installed libraries that are in package.josn.
