It is ugly solution but I resolved like below.

import pdfMake from "pdfmake/build/pdfmake";
import pdfFonts from "pdfmake/build/vfs_fonts";
import { Document, Page, pdfjs } from 'react-pdf'
pdfjs.GlobalWorkerOptions.workerSrc = `//cdnjs.cloudflare.com/ajax/libs/pdf.js/${pdfjs.version}/pdf.worker.js`

[moffsugita]

npm install --save-dev pdfjs-dist

and

pdfjs.GlobalWorkerOptions.workerSrc = 'node_modules/pdfjs-dist/build/pdf.worker.js';

@jp3492, this issue was exclusive to React-PDF 3.x. Try 4.x.
