Adding

node: {
  fs: 'empty'
}

to webpack config file and the error is gone. Not sure how it works, It seems like webpack did some thing with fs module in web target.

add the following to your Webpack config:

node: {
   fs: "empty"
}

The issue has been acknowledged and we are in process of figuring out a good fix. No need for "me too"s. Please add a thumbs up on the original issue if you want to do that. 👍

Did you can to unpublish this version? It will keep calm to all of us

[joshwiens]

@PredokMiF You don't unpublish anything, ever.

The workaround is sufficient and the bug is actually in webpack, related to fs in the web target.

WORKAROUND thanks to @hdnha11 / @mehdivk

node: {
  fs: 'empty'
}

If using this workaround isn't viable, version lock to the previous minor version.

@bebraw With your fix of this issue, I have a Uncaught ReferenceError: Buffer is not defined in the lib/convert-source-map.js file, in the browser.

@fklingler I have a proposed fix for that at #453 . Still waiting for some approvals before I can push it. Feel free to give that a go and let me know how it goes.
