azurerm_api_management_backend requires certificate

[bruceharrison1984]

resource "azurerm_api_management_backend" "example" {
  name                = "${local.app_id}-function-app"
  resource_group_name = "${azurerm_resource_group.example.name}"
  api_management_name = "${azurerm_api_management.example.name}"
  protocol            = "http"
  url                 = "https://${azurerm_function_app.example.default_hostname}/api"
  resource_id         = "https://management.azure.com/subscriptions/33a6b2c9-623b-4dad-acda-0a68f726abfc/resourceGroups/example-dev/providers/Microsoft.Web/sites/example-dev"

  credentials {
    header = {
      x-functions-key = "some-key"
    }
  }
}

When attempting to use the credentials block to attach headers, the request fails due to the certificate property being empty.

Error: Error creating/updating backend "example-dev-function-app" (API Management Service "example-dev" / Resource Group "example-dev"): apimanagement.BackendClient#CreateOrUpdate: Failure responding to request: StatusCode=400 -- Original Error: autorest/azure: Service returned an error. Status=400 Code="ValidationError" Message="One or more fields contain incorrect values:" Details=[{"code":"ValidationError","message":"'certificate' should not be empty.","target":"credentials.certificate"}

In my case, I'm not utilizing backend certificates. I presume I can work around this by providing certs and not using them on the backend, but given that certificate is an optional field it seems strange that it is required.
