Node.js core modules errors on Metro bundle

[dmonserr]

Hello,

I'm working on upgrading my react native application to use React Native 0.79.3, React 19, and Expo 53.

When I upgraded to 0.79.3 and React 19, I ran into this error:

error Unable to resolve module util from /../../../../node_modules/contentful/dist/contentful.cjs: util could not be found within the project or in these directories:
  node_modules
  268 |
  269 | var Stream$2 = require$$0$1.Stream;
> 270 | var util$3 = require$$1;
      |     ^^^^^^^^^^^^^^^^^^^
  271 | var delayed_stream = DelayedStream$1;
  272 | function DelayedStream$1() {
  273 |   this.source = null;.

I'm on Contentful version ^11.7.0 and was prior to this upgrade so not sure why this is an issue now.

Update: I believe this is related to: expo/expo#36551

Since when I added unstable_enablePackageExports: false, my metro bundler began passing without the error above.

Hello @dmonserr, thanks for raising this. Based on your comment, do you believe there is still an issue in the contentful.js package? Or does the issue lay solely in expo?

[dmonserr]

No, it is an issue with contentful.js - it's not compatible with the newest versions of Metro/Expo/RN.

You guys need to add support for the newer versions.

Thank you for the report. We found issues with react-native while converting our contentful-managment.js to ESM. We are currently working on a fix there and will then backport this fix to contentful.js

So soon we will support latest expo/metro/react-native. Stay tuned!

This is great news @axe312ger ! Will this be available in v12? Or can you update this thread when it's on a stable branch?
