I can confirm that problem exists on Android.

Hey @meftunca 👋 Could you (or someone who can reproduce this issue) prepare a showcase repo to reproduce this issue? 🙏

[piaskowyk]

At first, I recommend clearing all application cache, for example: rm -rf ./node_modules && yarn && cd ios && pod deintegrate && pod install && cd .. && yarn start --reset-cache"

[SergiOnGit]

Exactly the same here. Cache resetting doesn't help.

I already tried and got the same error

[meftunca]

I think the source of the problem is HERMES

[meftunca]

@piaskowyk Can you give an estimated date for the solution?

[samrith-s]

@piaskowyk I am getting this same issue, and unable to figure out why. I have a detail comment here. Been stuck with it for around 2 months.

[samrith-s]

Also figured by logging, global doesn't have __reanimatedModuleProxy as a property. So global.__reanimatedModuleProxy is always undefined

[samrith-s]

If you want a reproduction, you can check out the Reanimated2 Playground sandbox created by Software Mansion. It has the same error.

Why this issue is closed ? I am having same problem on android on latest version of this library.. (using hermes)

After months of trying to figure out why, on iOS, reanimated 2.0 -2.2 was subtly not working and why 2.3 was running into this issue, I think the root problem currently is this. We had a custom RCTBridgeDelegate instead of using our AppDelegate like the template/example apps use. To fix the issue if you also have a bridge delegate, you can either:

1) Implement the requisite sourceURLForBridge method on your AppDelegate class and use your app delegate as a delegate for your bridge. 2) Make your custom RCTBridgeDelegate a subclass of UIResponder.

This is what worked for us as well just yesterday!
