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 upgrade helper successfully for this process.

During this upgrade, we encountered the error mentioned above.

./gradlew build
The error:

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

project.ext.react = [

    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"

Did you find any solutions? I am facing the same issue, trying to upgrade from 0.70.0 to 0.72.0

@mgphall Your error message is indicating the file wasn't found at C:\projects\core-platform-frontend\src\main.tsx but your entry file (according to build.gradle prior to your changes) is at apps/colleague-portal-native/src/main.tsx.

Is it possible you went up to high in your directory structure when you changed to entryFile = file("/../../src/main.tsx")?
