Error installing helm chart eks/aws-load-balancer-controller

Hello,

I have been trying to install the AWS Load Balancer Controller add-on as detailed here: https://docs.aws.amazon.com/eks/latest/userguide/aws-load-balancer-controller.html

(I have pulled the needed image from ECR and pushed it to my own repo..)

When I try a helm install dry-run I get the following error:

helm install aws-load-balancer-controller eks/aws-load-balancer-controller \
-n kube-system  \
--set clusterName=myCluster \
--set serviceAccount.create=false \
--set serviceAccount.name=aws-load-balancer-controller \
--set image.repository=myrepo/aws-load-balancer-controller \
--set image.tag=2.4.1  \
--dry-run

Error: unable to build kubernetes objects from release manifest: unable to recognize "": no matches for kind "IngressClassParams" in version "elbv2.k8s.aws/v1beta1"

Additional info:
