Firebase Database Crash - NullPointerException toLowerCase

I cannot fully confirm what is going on there, but:

  1. Add your app package name to your Firebase project settings
  2. Make sure you can see some database in Realtime Database page, so RTDB has been enabled for the project
  3. Download an updated google-services.json, and update the Kodular project. It is very important the file is downloaded after those two steps, as it will be different
  4. Try building the APK. google-services.json is tied to specific package names, and it’s very likely the Companion is not in the allowlist…
