undefined is not an object (evaluating '_toConsumableArray(Array(length)).map')

See original GitHub issue

Description

I’ve been receiving the error undefined is not an object (evaluating '_toConsumableArray(Array(length)).map') and I have no idea where it comes from. I’ve tried to not render anything but the error still persists. It must be one of the worklets (useDerivedValue, useAnimatedStyle) because it’s being thrown async (after the render func returns)

For some reason spread and rest operators works for me with latest releases of both Reanimated and React Native. I’ll double check

I’ll finish my implementation, then I’ll help debug this. Would be good to support this on hermes since RN 0.64 will ship with hermes opt-in on iOS.
