Disable ARM_PROVIDER_ENHANCED_VALIDATION

ENV

$ ARM_PROVIDER_ENHANCED_VALIDATION=false terraform plan

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the
following symbols:
  + create

Terraform will perform the following actions:

  # azurerm_resource_group.rg-taiwannorth will be created
  + resource "azurerm_resource_group" "rg-taiwannorth" {
      + id       = (known after apply)
      + location = "taiwannorth"
      + name     = "rg-taiwannorth"
    }

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

──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────

Note: You didn't use the -out option to save this plan, so Terraform can't guarantee to take exactly these actions if you
run "terraform apply" now.
