Dynamic requires are not currently supported by rollup-plugin-commonjs

When I use Rollup (https://rollupjs.org/) to bundle Winston, the following error is thrown when running the app:

node example/index.js        
/Users/mike/logging/lib/bundle.js:21
        throw new Error('Dynamic requires are not currently supported by rollup-plugin-commonjs');
        ^

The issue is caused by https://github.com/winstonjs/logform/blob/master/index.js#L27. Ideally, it’d be great to revert back to https://github.com/winstonjs/logform/commit/972dbece432dbda7a0aeae4c4a7ac8d549821a78#diff-168726dbe96b3ce427e7fedce31bb0bcL21. Although more verbose, it would open up Winston to being bundled by Rollup once https://github.com/winstonjs/winston/pull/1100 is merged.

This is also a major issue when trying to integrate with https://github.com/zeit/pkg.

This issue also causes a slew of warnings (that then become runtime issues I have to assume, looking at the output files) with evanw/esbuild. It looks like my best workaround for the time being is to fork this repo and use https://classic.yarnpkg.com/en/docs/selective-version-resolutions/ to point at that fork?
