Source map warnings

Using this library I’m getting warnings like these in browser console and webpack dev server output. I’m using typescript in my project. Do you know if there’s something I could do to prevent these warnings?

./node_modules/web-streams-polyfill/dist/polyfill.min.js
Module Warning (from ./node_modules/source-map-loader/dist/cjs.js):
Failed to parse source map from 'C:\Users\vinca\Documents\Code\proton-drive\node_modules\web-streams-polyfill\src\lib\abort-signal.ts' file: Error: ENOENT: no such file or directory, open 'C:\Users\vinca\Documents\Code\proton-drive\node_modules\web-streams-polyfill\src\lib\abort-signal.ts'

Hang on, something is wrong indeed with the polyfill’s source maps! Each entry in the sourcesContent array is null! 🤯 (See the file on unpkg.com)

I think I didn’t notice at first because I did git checkout v2.1.1 && npm install. However, since I already had newer versions of Rollup and its plugins installed on master, it may not have downgraded them? I just tried it again locally by running npm ci instead, and I can now reproduce the broken source maps.

I also tried building the tip of master and using that inside of the test project, and that works: the new source map has proper source contents. So you can expect the next release to fix the problem. 🙂

If it’s okay for you, I’ll wait until the 3.0.0 release to ship this fix. For the time being, you can use your exclude workaround. Sorry about the inconvenience!

Version 3.0.0 has been released, with working source maps this time. 😁
