APK Signing Scheme in Oculus

I am receiving this error when trying to upload an oculus build:

APK Signed With Signature Scheme V1
The APK is signed with deprecated signature scheme V1. Please use V2 or V3 signing for this type of application.

Any thoughts on what this might be?

Are you sure you are building with Gradle checked?

Otherwise check your SDK and NDK android settings in screenshots shown in steps 12 & 14 of the Oculus unreal quickstart guide:
