I have my helm_release setup as the following:

resource "helm_release" "argocd" {
  namespace  = kubernetes_namespace.argocd.metadata.0.name
  name       = "argocd"
  repository = "https://argoproj.github.io/argo-helm"
  chart      = "argo-cd"
  version    = var.argocd_chart_version
[...]
}

Now I want to add templates and triggers to the chart. I have them in argocd/triggers.yaml and argocd/templates.yaml. Example of triggers.yaml (I have tried both with a trigger. prefix and without):

trigger.on-created: |
  - description: Application is created.
    oncePer: app.metadata.name
    send:
    - app-created
    when: "true"
trigger.on-deleted: |
  - description: Application is deleted.
    oncePer: app.metadata.name
    send:
    - app-deleted
    when: app.metadata.deletionTimestamp != nil

The helm_release set part is as follows:

  set {
    name  = "notifications.triggers"
    value = file("${path.module}/argocd/triggers.yaml")
  }

However, this results in the following error:

│ Error: YAML parse error on argo-cd/templates/argocd-configs/argocd-notifications-cm.yaml: error converting YAML to JSON: yaml: line 30: could not find expected ':'
│
│   with module.prod.module.kubernetes.helm_release.argocd,
│   on moduleskubernetesargocd.tf line 19, in resource "helm_release" "argocd":
│   19: resource "helm_release" "argocd" {

How do I set my triggers and templates correcly using Terraform? Preferably by loading the file but if I need to define then manually that is also doable.
