Using the component in jest testsing

[sandhya-sago]

I am having trouble using Document component in a way that works in jest testing.

Setup:

import { Document, pdfjs } from 'react-pdf';
import 'react-pdf/dist/Page/AnnotationLayer.css';

pdfjs.GlobalWorkerOptions.workerSrc = new URL(
  'pdfjs-dist/legacy/build/pdf.worker.js',
  import.meta.url,
).toString();

Using this component in a jest test gives the error

    1: "Warning: Error: Setting up fake worker failed: \"Cannot find module 'file:///Users/sgovindaraju/Documents/TEL/tel-compass/tantei_client/app/components/common/PDFViewer/pdfjs-dist/build/pdf.worker.js' from '../node_modules/pdfjs-dist/build/pdf.js'\"."

Both legacy and regular versions give the same error. Things are working fine in the UI.

Versions:

pdfjs-dist 3.11.174 
react-pdf 7.7.0
jest 29.7.0
node v20.10.0
webpack 5.89.0

Is there some setting to enable to run jest tests, instead of mocking out Document? Thanks!
