Uniwind causes build failure on Expo 55 when enabling tree shaking

[brianangulo]

What happened?

When exporting the JS bundle Expo 55 builds fail if tree shaking is enabled, refer to: https://docs.expo.dev/guides/tree-shaking/

In other words when setting the following 2 environment variables:

EXPO_UNSTABLE_METRO_OPTIMIZE_GRAPH=1 EXPO_UNSTABLE_TREE_SHAKING=1

We get the following error:

Failed to generate Hermes bytecode for: /Users/brian/Main/Repos/min-repro-uniwind/node_modules/expo-router/entry.js

We would expect uniwind to not cause a failure in this case, when tree shaking is disabled the build succeeds.

Steps to Reproduce

1. Clone reproducible repo
2. Install packages via bun i
3. Run a JS bundle export step via with tree shaking enabled EXPO_UNSTABLE_METRO_OPTIMIZE_GRAPH=1 EXPO_UNSTABLE_TREE_SHAKING=1 npx expo export --platform android
4. See failure
