I am able initialize the terraform

• provider.helm: version = "~> 2.0"
• provider.kubernetes: version = "~> 2.0"
• provider.null: version = "~> 3.1"

Terraform has been successfully initialized! using terraform Terraform v0.12.20 but when I run "terraform apply" I am getting this error "The provider provider.helm does not support data source "helm_repository"." here is my configuration.

data "helm_repository" "helm-charts-all" {
  name = "helm-charts-all"
  url  = var.helm_repo
  username = ""
  password = ""
  }
