errors when run ing helm commands when following the starter-project for kubernetes clusters

While following the starter-project for kubernetes clusters https://github.com/digitalocean/Kubernetes-Starter-Kit-Developers/blob/main/03-setup-ingress-ambassador/README.md

At step 3 i have to run the following command

HELM_CHART_VERSION="6.7.13"

helm install ambassador datawire/ambassador --version "$HELM_CHART_VERSION" \
    --namespace ambassador \
    --create-namespace \
    -f "03-setup-ingress-ambassador/assets/manifests/ambassador-values-v${HELM_CHART_VERSION}.yaml"

before this i had to run

helm repo add datawire https://www.getambassador.io

Which installed datawire/ambassador 6.9.3 not 6.7.13. So i changed the HELM_CHART_VERSION to 6.9.3 and refactored the ambassador-values-v${HELM_CHART_VERSION}.yaml" so it can be found when running the script.

But i end up getting the following response

When i try to look at if anything has been installed with kubectl get crd --all-namespaces | grep ambassador

I this response
