Helmet setup not working with Helm 3

[entrymon]

I did clone of this repo.

Then tried helm install

helm package . --debug

and then

helm install helmet-chart-0.0.1.tgz --debug

but I got --generate-name error so I did

helm install helmet-chart-0.0.1.tgz --debug --generate-name

but then it fails

helm.go:84: [debug] unable to recognize "": no matches for kind "Deployment" in version "extensions/v1beta1"
unable to build kubernetes objects from release manifest
helm.sh/helm/v3/pkg/action.(*Install).Run

I also tried

kubectl apply -f manifest.yml

but it returns me

error: unable to recognize "manifest.yml": no matches for kind "Deployment" in version "extensions/v1beta1" I am using helm 3 and minikube.
