}

Expected Behavior

I am expecting to create a function app with it's plan and a slot called staging.
The slot function should have the integration with the subnet azurerm_subnet.example

Actual Behavior

The apply ends with the following error message, all the resources have been created expect the integration with the vnet that I need to create manually from the portal.

Got the same error.

Error: Error parsing Azure Resource ID %!q(*web.AppServiceResourceID=)

Also if you are calling from a module. There's no way you can add azurerm_app_service_slot name in the module output file.

@uolter, @ziontech-devops for app_service_id field, we could not use azurerm_app_service_plan id, but should use id of azurerm_app_service or azurerm_function_app , Could you please try use following config ?

resource "azurerm_app_service_slot_virtual_network_swift_connection" "example" {
  slot_name      = azurerm_function_app_slot.example.name
  app_service_id = azurerm_function_app.example.id
  subnet_id      = azurerm_subnet.example.id
}

I will also made a PR to update this document and enhance the validation rule.
