With a clean create-expo-app I added iconoir-react-native and got the following error:

While trying to resolve module `iconoir-react-native` from file `project_path/app/(tabs)/_layout.tsx`, the package `project_path/node_modules/iconoir-react-native/package.json` was successfully found. However, this package itself specifies a `main` module field that could not be resolved (`project_path/node_modules/iconoir-react-native/dist/esm/index.js`. Indeed, none of these files exist:

  * project_path/node_modules/iconoir-react-native/dist/esm/index.js(.web.ts|.ts|.web.tsx|.tsx|.web.mjs|.mjs|.web.js|.js|.web.jsx|.jsx|.web.json|.json|.web.cjs|.cjs|.web.scss|.scss|.web.sass|.sass|.web.css|.css)
  * project_path/node_modules/iconoir-react-native/dist/esm/index.js/index(.web.ts|.ts|.web.tsx|.tsx|.web.mjs|.mjs|.web.js|.js|.web.jsx|.jsx|.web.json|.json|.web.cjs|.cjs|.web.scss|.scss|.web.sass|.sass|.web.css|.css)

I've tried adding .mjs extension to metro.config, but that didn't help.

I've noticed the following line

in reality this is dist/esm/index.mjs not .js

When overwriting it to .mjs it works fine, and I no longer get the error message.

Is this a mistake or am I missing something ?
Thanks!
