Hey! 👋

The issue doesn't seem to contain a minimal reproduction.

Could you provide a snack or a link to a GitHub repository under your username that reproduces the problem?

Hey!

Could you pleas provide more information? Did you use the new (experimental) react native debugger, chrome debugger or some other debugging tool?

Can you provide a repro or share the repository?

i user react native debugger https://github.com/jhen0409/react-native-debugger because it support debug request network.
i use react native 0.75.1, and i need to debug my request network. so i used react native debugger with enabled network inspect. because i use @react-navigation/drawer which it use react-native-reanimated 3.15.0. an error occured: Cannot convert undefined or null to object located in /node_modules/react-native-reanimated/src/js-reanimated/index.ts --> _updatePropsJS --> component.props

Thank you for response. I can reproduce the issue while I am debugging JS remotely with react-native-debugger. I am not sure it we will able to fix that, though, as this debugger doesn't support JSI, which reanimated uses.

From the react-native-debugger README:

⚠️ This app is currently only supported old Remote Debugger, if you're looking for new debugger support (e.g. Hermes / JSI / New Architecture) of React Native Debugger, please follow jhen0409/react-native-debugger#774.

I will look into this issue and check it we can do something.

@TonyFTannous-Byd Could you check if changes I made in the #6437 PR fix your issue? You can make the same changes in node_modules/react-native-reanimated and see if you still see this error.

If you still have some problems, don't hesitate to re-open the issue and ask.

Hi @MatiPl01,
I was facing the same problem as @TonyFTannous-Byd mentioned and opened this ticket

I tried the fix that you have created and merge in this PR 6437

This issue of debuggerWorker.js:69 TypeError: Cannot convert undefined or null to object is fixed now

But now when I connected with debugger my Tab navigation is not working
whereas drawer and stack navigation is working fine.

Hey @abdulmoizshaikh!

Would you be able to share your code or a small repro showing the issue? Not everything will work while you use remote JS debugging but I will check what we can do if you share some code.

[TonyFTannous-Byd]

hey @MatiPl01
is your fixing (PR 6437) is not merged in the main branch?
because i use the last version of react-native-reanimated ^3.15.3, and the issue still exists when using @react-navigation/drawer

[MatiPl01]

Hey @TonyFTannous-Byd!

Yes, it was merged. If you still encounter this problem, can you please open a new issue and describe it more in detail (I mean, include some repro or code snippet that causes this error)?
