Error/Warning in React Native with latest Beta: Package swr has been ignored because it contains invalid configuration. Reason: Package subpath './package.json' is not defined by "exports"

Having just installed the latest version of swr "swr": "^1.0.0-beta.9" with React Native "react-native": "^0.64.2", the Metro Bundler shows the following warning:
warn Package swr has been ignored because it contains invalid configuration. Reason: Package subpath './package.json' is not defined by "exports" in /Users/.../node_modules/swr/package.json

Node version v16.5.0

I'm playing react native with expo, didn't have see any warinings for it when I installed swr 1.0.0-beta.9.

IMO a library doesn't have to define package.json in exports if it's not necessary. Found a related issue of react-native cli itself here. Looks like it has some problem with resolving package.json. The issue is more like on react native cli side.

@beetlebum package.json exports is still added in #1313 since other bundler might also have this issue when resolving <module>/package.json. Will be released into next round. Thanks for reporting! 🙏
