I am running the following command,

helm install airflow \
    --set executor=CeleryExecutor \
    --set workers.keda.enabled=true \
    --set workers.persistence.enabled=false \
    --namespace airflow \
    astronomer/airflow

which is resulting in this error:

Error: unable to build kubernetes objects from release manifest: unable to recognize "": no matches for kind "ScaledObject" in version "keda.k8s.io/v1alpha1"
