Error: Cannot find native module 'ExpoAsset', js engine: v8
Hello,
Currently using v8 our expo app. When upgrading from sdk 50 to sdk 51, this issue arise at startup for real devices with Android <= 11 (works fine on IOS / Android > 11, and simulators) :
To reproduce, you can download minimum sample here : https://github.com/Baart/expo51-v8-android11/tree/main
Here are the logs :
Android Bundled 252ms index.js (572 modules) WARN No native ExponentConstants module found, are you sure the expo-constants's module is linked properly? ERROR Error: Cannot find native module 'ExpoAsset', js engine: v8 ERROR Invariant Violation: "main" has not been registered. This can happen if:
- Metro (the local dev server) is run from the wrong folder. Check if Metro is running, stop it and restart it in the current project.
- A module failed to load due to an error and
AppRegistry.registerComponentwasn't called., js engine: v8`
Sample app was created like this : npx create-expo-app -t bare-minimum@51 Follow v8 install https://github.com/Kudo/react-native-v8 npm run android
