Hi @Eillot29, sorry for the slow response, unfortunately the Predictive Autoscaler is only supported on Kubernetes versions 1.23 and above. This is because it needs the autoscaling/v2 API to be available, which was only added in 1.23.

https://kubernetes.io/blog/2021/12/07/kubernetes-1-23-release-announcement/#horizontalpodautoscaler-v2-graduates-to-ga

I've updated the README to clarify around supported Kubernetes versions.

Thanks for raising this.
