Error running react-native run-android --variant=release (Task 'installReleaseDebug' not found in root project 'gnosisapp'.)

Question

I'm having this error trying to do react-native run-android --variant=release

Starting JS server...
Running /home/sonic182/Android/platform-tools/adb -s ZY2232QD4K reverse tcp:8081 tcp:8081
Building and installing the app on the device (cd android && ./gradlew installReleaseDebug)...

FAILURE: Build failed with an exception.

* What went wrong:
Task 'installReleaseDebug' not found in root project 'gnosisapp'.

* Try:
Run gradlew tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

(node:24877) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): TypeError: Cannot read property 'message' of undefined

I'm over Ubuntu 16.04, I have done all the steps from here https://facebook.github.io/react-native/docs/signed-apk-android.html until the testing step where I have to do react-native run-android --variant=release

What could it be? :/ Thanks

If you are running React Native 0.39.x, please use this:

react-native run-android --configuration=release
