com.facebook.jni.CppException: Cannot read property '__workletHash' of undefined

[varungupta85]

This package has external dependencies of react-native-reanimated and react-native-gesture-handler which must be installed separately. Before opening an issue related to animations or gestures please verify that you have completed ALL installation steps, including the changes to MainActivity.

Describe the bug I get the following errors when I try to use this library in production app. The app works fine in debug mode.

iOS

libc++abi: terminating due to uncaught exception of type facebook::jsi::JSError: undefined is not an object (evaluating 'fun.__workletHash')

Even though the problem is rooted in the react-native-reanimated package, it only surfaces when I use this package to make a list draggable and that too only in release mode. I suspect it has something to do with some plugin configuration/setup but don't know how to find the problem.

Please help if you know what could be wrong.

To Reproduce I am unable to provide a snack for this issue.

Platform & Dependencies Please list any applicable dependencies in addition to those below (react-navigation etc).

• react-native-draggable-flatlist version: 4.0.1
• Platform: iOS and Android
• React Native or Expo version: 0.72.5
• Reanimated version: 3.6.1
• React Native Gesture Handler version: 2.14.0

Additional context I am using it in monorepo setup using Yarn Workspaces.
