I get an error when I install the helm chart I created.

helm install -f values.yaml --dry-run testbb ./

I change the indent and make it like yamls. I use "kubectl get -o yaml" many times, but it doesn't work.

Line 50 in yaml file contains volume name: frontend-http

Does anyone know how to solve this, please? Here is the entire yaml template file:
