Diff does not show in terraform plan

[yashbhutwala]

Diff in tf plan is not the same as diff via the helmfile cli:

Terraform v0.14.11
Configuring remote state backend...
Initializing Terraform configuration...
local_file.kubeconfig: Refreshing state... [id=61cbd7e426fc6807211cc7557f8ab62504c8f440]
helmfile_release_set.nginx: Refreshing state... [id=c31p18vgb56ccqb6m9og]
helm_release.example: Refreshing state... [id=ingress-nginx]

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  + create
  ~ update in-place

Terraform will perform the following actions:

  # helmfile_release_set.nginx will be updated in-place
  ~ resource "helmfile_release_set" "nginx" {
      ~ content           = <<-EOT

  # local_file.kubeconfig will be created

      + directory_permission = "0777"
      + file_permission      = "0777"

      + id                   = (known after apply)
    }

Plan: 1 to add, 1 to change, 0 to destroy.
