Error when running "ionic cordova build android --prod --release" in Terminal

I get the following error when trying to build an Android project. This started recently, I believe after I updated to Android Studio 3.2.1. I am using macOS Mojave and Ionic 4.3.1.

FAILURE: Build failed with an exception.

  • What went wrong:

A problem occurred configuring root project ‘android’.
