Problem
Description Upgrade from 0.68.1 to 0.70.0. Builds fine in Xcode. Launches Simulator. Splash screen for app appears. and then it crashes with the error: ERROR Invariant Violation: Failed to call into JavaScript module method AppRegistry.runApplication(). Module has not been registered as callable. Registered callable JavaScript modules (n = 11): Systrace, JSTimers, HeapCapture, SamplingProfiler, RCTLog, RCTDeviceEventEmitter, RCTNativeAppEventEmitter, GlobalPerformanceLogger, JSDevSupportModule, HMRClient, RCTEventEmitter. A frequent cause of the error is that the application entry file path is incorrect.

Fix Invariant Violation Error After Upgrading to React Native v0.70
The error occurs because the application entry file path may be incorrect or the JavaScript bundle is not properly loaded. This can happen due to changes in the module registration process in React Native v0.70, which may require updates to the app's entry point or configuration.
Awaiting Verification
Be the first to verify this fix
- 1
Verify Entry File Path
Ensure that the entry file (usually index.js or App.js) is correctly specified in your app's configuration. Check the AppRegistry registration to confirm it points to the correct file.
javascriptimport { AppRegistry } from 'react-native'; import App from './App'; AppRegistry.registerComponent('YourAppName', () => App); - 2
Clear Cache and Rebuild
Clear the Metro bundler cache and rebuild the project to ensure that all assets and modules are freshly compiled. This can resolve issues related to stale caches.
bashnpx react-native start --reset-cache - 3
Update Dependencies
Ensure that all dependencies are compatible with React Native v0.70. Check the package.json file and update any outdated packages that may not support the new version.
bashnpm outdated npm install <package-name>@latest - 4
Check Hermes Configuration
If using Hermes, ensure that it is correctly configured in your project. Check the android/app/build.gradle file for the Hermes settings and verify that Hermes is enabled.
groovyproject.ext.react = [ enableHermes: true, // clean and rebuild if changing ]; - 5
Run Application
After making the above changes, run the application again in the simulator to check if the issue is resolved.
bashnpx react-native run-ios
Validation
Confirm that the application launches successfully without the Invariant Violation error. Check the console logs for any remaining errors and ensure that the app's main screen is displayed correctly.
