Cannot add init container

[yash95shah]

Does this issue reproduce with the latest release?
Yes
What operating system and processor architecture are you using (kubectl version)?

kubectl version Output

$ kubectl version
Client Version: v1.29.1

What did you do?
I am trying to pass in an input for init container using this value input to the helm chart (for testing)

initContainer:
  enabled: true
  image: "alpine:3.8"
  imagePullPolicy: "Always"
  resources:
    requests:
      memory: "32Mi"
      cpu: "100m"
    limits:
      memory: "64Mi"
      cpu: "200m"
  env:
    - name: "ENV_VAR2"
      value: "value2"
  command: ["/bin/sh", "-c"]
  args: ["echo Hello, Helm!"]

What did you expect to see?
I expect the redis cluster resource and eventually statefulsets' pods to have this init container
What did you see instead?
I get this error running the command helm upgrade cluster-redis ot-helm/redis-cluster -f redis_conf.yaml -n ot-operators

Error: UPGRADE FAILED: template: redis-cluster/templates/redis-cluster.yaml:78:20: executing "redis-cluster/templates/redis-cluster.yaml" at : wrong number of args for include: want 2 got 1
