Helm template error

[telderfts]

I am currently trying to install grafana in HA via Helm using the following values file, DB info has been redacted for security.

helm install grafana grafana/grafana -f grafanavalues.yaml --namespace grafana

replicas: 2 # Adjust the number of replicas as needed

database:
type: mysql
host: :3306
name: grafana
user: grafana
password:

persistence:
type: pvc
enabled: true
storageClassName: gp3
accessModes:
- ReadWriteOnce
size: 100Gi

env:
GF_UNIFIED_ALERTING_HA_PEERS: "grafana-alerting.grafana:9094"
GF_UNIFIED_ALERTING_HA_LISTEN_ADDRESS: "${POD_IP}:9094"
GF_UNIFIED_ALERTING_HA_ADVERTISE_ADDRESS: "${POD_IP}:9094"

extraContainers:

• name: grafana-alert
  ports:
  • containerPort: 9094
    name: grafana-alert
    protocol: TCP

service:
type: ClusterIP

additionalServices:

• name: grafana-alerting
  type: ClusterIP
  clusterIP: None
  ports:
  • port: 9094
    targetPort: 9094

However when I go to run the helm chart I get the following error..

"Error: INSTALLATION FAILED: template: grafana/templates/deployment.yaml:52:10: executing "grafana/templates/deployment.yaml" at <include "grafana.pod" .>: error calling include: template: grafana/templates/_pod.tpl:1207:10: executing "grafana.pod" at <.>: wrong type for value; expected string; got []interface {}"
