Packaging for Android fails with no error

My Ionic app builds locally fine, also the package builds fine on Ionic cloud for iOS but it fails for Android without any error:

BUILD SUCCESSFUL in 1m 12s
46 actionable tasks: 46 executed
Built the following apk(s): 
	/usr/src/app/platforms/android/app/build/outputs/apk/release/app-release.apk
$ cordova build android --release -- --keystore=android.keystore --storePassword=***** --alias=Android --password=***** success
Running after script...
$ run "clean-up"
Running Stage clean-up for Job: 5519616
ERROR: Job failed: exit status 1

Any input would be appreciated.
