Command to install the mesh controller does not work

[fabianmartins]

The command here: https://www.appmeshworkshop.com/mesh_nodejs/install_appmesh_controller/ right after the sentence "Now install App Mesh Controller into the appmesh-system namespace using the project’s Helm chart, specifying the service account you just created" does not work. it Returns:

Error: Kubernetes cluster unreachable: exec plugin: invalid apiVersion "client.authentication.k8s.io/v1alpha1"

Workaround - use helm v3.8.2
curl -L https://git.io/get_helm.sh | bash -s -- --version v3.8.2

And to make sure that this will work you need to use kubectl Client Version: v1.16.8

It seems like the problem is the Helm version 3.9.
This is a workaround to downgrade to 3.8:

curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3
chmod 700 get_helm.sh
DESIRED_VERSION=v3.8.2 bash get_helm.sh
