app crashes if debugging mode is enabled

Description

I am using react-native-reanimated as a dependency of react-native-draggable-flatlist. Since I started using reanimated, app crashes if debugging mode is enabled. Once I uninstall reanimated package then app runs in debugging mode perfectly.

Screenshots

Steps To Reproduce

1. Just install the react-native-reanimated as per docs and then enable debugging mode. You can encounter this error

Expected behavior

debugging mode should work as usual

Actual behavior

app crashes if debugging mode is enabled

Snack or minimal code example

No specific code is required. Just installing the package is sufficient.

Package versions

• React: “16.13.1”
• React Native: “0.63.2”
• React Native Reanimated:“2.0.0-rc.2”
• NodeJS: v10.16.2

This is not related just to reanimated and the debugger support is not a thing reanimated can “fix”, since it’s because of react native architecture (or better, turbo modules). While it’s annoying that the app just crashes when you enable remote debugging, it doesn’t seem that reanimated can do anything more than adding a huge warning box to the installation instructions.

• Like the box there says, you can use Flipper to debug your app.
• Some tips on how to debug were also mentioned in RN’s Turbo Modules topic. You can try using Safari to debug iOS app.
• There are also special Hermes debugging instructions.
• With expo it’s more complicated as you can find in their documentation. You can follow the feature request and try this workaround in the meanwhile.
• You can join the discussion at react native’s proposal repo and propose a solution. Or just subscribe.
