EAS build seems to fail when hermes is enabled on a monorepo project.
- Managed workflow
eas-cli/0.34.1 darwin-x64 node-v15.14.0expo --version // => 4.12.11- Expo SDK43
I’m trying to set up a monorepo with Expo and NextJS. I used this repo as a starter GitHub - axeldelafosse/expo-next-monorepo-example: Create a universal React app using Expo and Next.js in a monorepo and so far it seems to be working really well in a dev environment. But when I tried to make a preview Android build, it failed with the following message:
> Task :app:bundleReleaseJsAndAssets FAILED
> Task :expo-modules-core:compileReleaseJavaWithJavac
[stderr] Note: Some input files use unchecked or unsafe operations.

Error: Gradle build failed with unknown error. Please see logs for the "Run gradlew" phase.
I tried to reproduce the problem with the monorepo example without changing any code and it still fails.
Switching the jsEngine field to jsc on app.config.js seems to fix the issue and the build completes successfully, but I’m not sure how I can get more information on why the build fails with Hermes.
Is there anything else I can do to debug why the build fails on EAS service? Can we get more detailed logs about that or do I need to run the Turle CI locally and see if I get any different results?
Thanks for your help!
