Things I’ve done to figure out my issue
[ X ] I used upgrade-helper to do my upgrade.
Upgrading version
0.70.15

0.70.15 to 0.71.19

We are in the process of upgrading our application/monorepo , which started at version 0.68 and is currently moving from RN 0.70.15 to 0.71.19. We are completing one upgrade per sprint and have been using the react-native-community.github.io/upgrade-helper successfully for this process.

During this upgrade, we encountered the error mentioned above.

./gradlew build
The error:
error The resource C:\projects\core-platform-frontend\src\main.tsx was not found.

The only change i can see it with regards to entry file is in the build gradle file

project.ext.react = [
entryFile: "apps/colleague-portal-native/src/main.tsx",
enableHermes: true, // clean and rebuild if changing
hermesCommand: "../../../../node_modules/react-native/sdks/hermesc/%OS-BIN%/hermesc"
]

to ->

react {
entryFile = file("/../../src/main.tsx")
println("entryFile: ${entryFile.get().asFile.absolutePath}") , <- the correct file path
hermesCommand = "../../../../node_modules/react-native/sdks/hermesc/%OS-BIN%/hermesc"
}

but I suspect its passing this section
