Warning: TypeError: Cannot read property 'bubblingEventTypes' of null

Describe the bug Warning: TypeError: Cannot read property 'bubblingEventTypes' of null

Dependency versions

• React Native version: 0.75.4
• React version: 18.3.1
• React Native Fast Image version: ^8.6.3

Note: if these are not the latest versions of each I recommend updating as extra effort will not be taken to be backwards compatible, and updating might resolving your issue.

I also encountered this issue, but reopening my emulators fixed it.Try closing and opening your simulator and android emulator.

I encountered same issue with same version, Solution -

1. delete node module and reinstall it
2. cd android && ./gradlew clean
3. npm run android <-- this is the main step

@mlcpro You've closed the issue. How have you solved the problem ?

[mlcpro]

@FelipeRaulino yes, i closed the emulators and reopened

This fixed the issue. But what could be the RCA ?

Rollback to old React-Native (under 0.75.4) as the new 0.76 use a new architecture which most of libraries are not yet updated and it throws this problem.

I had the same issue with the iOS simulator and pod install fixed it for me.

@1mehdifaraji Thank you for providing a solution. I have one question. When building for iOS using Expo, I get the same error: Warning: TypeError: Cannot read property 'bubblingEventTypes' of null. You mentioned that it was resolved with pod install, but did you do anything else besides that?

[1mehdifaraji]

@hayata-0 You're welcome, no I only did pod install but I'm not using expo so you may need to rollback react-native or expo or try installing and using an earlier version of the library and try clearing cache and rebuild.

[IonutDaniel99]

I figured out after several trial and error that this was also a problem from patches of different libraries. In my case i had an error on React-Charts so i did a patch. That patch created the bubblingEventTypes because the return type was incorrect .

Might be worth looking if you have applied patches over node_modules libraries.

I'm receiving the same error with Flashlist in expo 52 ,is there any fix ?

[ArjunK01]

doing a whole eas rebuild fixed this for me

[iamabdulhaseeb]

I faced this same issue with react-native-blasted-image, I deleted app from my emulator and re-build the project, its working now

I also encounter this issue using Expo 52. Doing the following steps did not work for me 🙃

• Delete node_modules and ios folders
• npx expo prebuild --platform ios
• Build project in XCode
• npm run dev

If you using Expo npx expo install expo-linear-gradient then import { LinearGradient } from 'expo-linear-gradient';

• Future reference for people that experience this error when directly using react-native-linear-gradient on expo.

I am facing the same issue while trying to use "LinearGradient" from react-native-linear-gradient and also I have tried using "expo-linear-gradient". Both are throwing the same issues. Any solve for that?

[diponkorcs]

If you using Expo npx expo install expo-linear-gradient then import { LinearGradient } from 'expo-linear-gradient';

• Future reference for people that experience this error when directly using react-native-linear-gradient on expo.

Thanks. Works for me.

If you are using LinearGradient

Make sure you are importing LinearGradient from the correct package: import LinearGradient from 'react-native-linear-gradient';

If you’re using Expo, make sure you're importing it from the correct Expo wrapper: import { LinearGradient } from 'expo-linear-gradient';
