Unable to convert app bundle to APK in android

Question

I am using Android studio 3.4.1. I was trying to convert the App bundle to APK using the bundle tool. I was unable to generate the APK file. I tried using Generate Apk file from aab file (android app bundle)

When I run the command

java -jar bundletool.jar build-apks  --bundle=app.aab --output=app.apks

I got the below error. Kindly suggest me a solution to generate the APK.

INFO: The APKs will be signed with the debug keystore found at 'C:\Users\~\
.android\debug.keystore'.
