Hey @bkensey , I think this has to do with the Xcode build scripts that React Native uses by default. Since your app is bare, you have direct access to these files and can modify them to point to the correct files (open up the .xcworkspace file in your ios directory, this will open Xcode, and you can go to the build scripts pane)
BTW, think this is the same as this post- Eas build for ios fails at fastlane step - no main.jsbundle:
