cordova android release failed in app:packageReleaseBundle

Question

I can build my Ionic 5 app for Android (cordova build android) but I get the following error when I try to build it for a release (cordova build android --release)

I have removed and re-installed cordova-android 10.1.2 several time, and I am using gradle 6.7.1.

I would like to know what I should check more to fix that problem, thanks!

Thanks!
