react-uploader UploaderProvider breaks production Next.js apps

[travis]

If I use UploaderProvider in a Next.js application it works fine in dev mode but breaks the app in production.

A very simple demonstration of this issue can be found in https://github.com/web3-storage/w3ui-swc-minify-bug - simply clone the repo and run npm install && npm run build && npm start to see the error.

I've tracked this down to something in the SWC minifier - as demonstrated on the fixed branch of the w3ui-swc-minify-bug repo the issue goes away if you disable SWC minification:

I don't think there's anything for us to do about this - creating this issue to track the bug I'm about to file in the Next.js repository.

Filed vercel/next.js#43052 so this will hopefully get fixed upstream.

this was fixed upstream! test repo works now.
