Global is Not Defined

[jjcfatras]

I keep running into this issue on startup. I'm using react-native-web with nextjs (page router) via the @expo/next-adapter https://www.npmjs.com/package/@expo/next-adapter. Attached is a screenshot of the error and of my next.config.js file.

Guten Tag, Hans here! 🍻

It looks like you're running into a "Global is Not Defined" issue with your setup. To help mrousavy investigate this, we really need more information. Could you please provide logs from your runtime? If you're using Xcode or Android Studio, you can find them in the logs window or use adb logcat for Android. This will help us understand what's going wrong.

And remember, if you want to support the project and get faster responses, consider sponsoring mrousavy at GitHub Sponsors. Thank you!

Note: If you think I made a mistake, please ping @mrousavy to take a look.

I am running into this as well after upgrading MMKV to 3.x from 2.x.

I'm running into this as well on Solito after upgrading to mmkv v3 and enabling new arch, the error is only on Next.js.
