The 'this' keyword is equivalent to 'undefined' at the top level of an ES module, and has been rewritten

[MichaelFBA]

We are using this library and noticed rollup / esbuild is throwing some warnings about the way the library has been exported.
rollup: https://rollupjs.org/troubleshooting/#error-this-is-undefined

../../node_modules/export-from-json/dist/esm/converters.js (12:22) The 'this' keyword is equivalent to 'undefined' at the top level of an ES module, and has been rewritten

Just curious of others are seeing the same warnings? I suspect I could just ignore the warnings in rollup but wanted to see if there was anything that could be done in the library?
