Fails to determine project configuration

I’m trying to run react native in a monorepo, and if I run the project with the old 2.9 version, I can run in development mode, if I override the native_modules.gradle-file like this:

-    def command = "node ./node_modules/react-native/cli.js config"
+    def command = "../../node_modules/react-native/cli.js config"

As well as run react-native start in my mobile folder, and run-android in my root folder in a separate terminal window.

But then can’t build for production, due to it not finding the node_modules/react-native/cli.js-file when I run with the --variant=release flag.

Now I’ve upgraded to version 3.0.1 of the @react-native-community/cli package, And added a configuration file in my root folder like so:

// react-native.config.js
module.exports = {
  project: {
    android: {
      sourceDir: './packages/mobile/android',
    },
    ios: {
      project: './packages/mobile/ios/mobile.xcodeproj',
    },
  },
}

Then I run yarn react-native run-android --root packages/mobile from root. However, it keeps complaining about my configuration.

React Native CLI failed to determine Android project configuration. This is likely due to misconfiguration. Config output: <config output>

If I run react-native config in my root directory, this is what I get:
