No matching export in "node-modules-polyfills:buffer" for import "default"

[keithbro-imx]

Hello!

I'm not sure if this is an issue with node-modules-polyfills or with the way that the library that I'm trying to use is built, but when I try to use https://github.com/wanseob/soltypes, and build my app, I get the following error:

✘ [ERROR] No matching export in "node-modules-polyfills:buffer" for import "default"

    node_modules/soltypes/build/index.es.js:1:7:
      1 │ import buffer from 'buffer';
        ╵        ~~~~~~

I've created a minimal repro here: https://github.com/keithbro-imx/buffer-polyfills-repro

For context, I ran in to this issue when using this library in a Remix app.

Would be great to get your thoughts on where the problem might be and how we might fix it.

Thanks in advance for your help!

The problem is in the polyfill library, unfortunately the library won’t accept PRs and I don’t want to maintain a fork, maybe I should try again searching for an alternative polyfill
