Problem

When creating a private_endpoint to a static webapp in Australia east region using terraform, you may get this error :

Performing CreateOrUpdateStaticSite:
│ unexpected status 400 (400 Bad Request) with error:
│ LocationNotAvailableForResourceType: The provided location ‘australiaeast’
│ is not available for resource type 'Microsoft.Web/staticSites'. List of
│ available regions for the resource type is 'westus2,centralus,eastus2,westeurope,eastasia'.

However, creating a private endpoint through the Azure Portal in the same region works fine.

Cause

This error occurs as we not provide the value of an optional attribute called subresource_namesunder the private_service_connectionblock. As per our documentation:

subresource_names is a list of subresource names which the Private Endpoint is able to connect to and corresponds to group_id.

Possible values are listed in the Microsoft documentation. For static sites, we need to use the sub-resources as staticSites

Solution

Update the configuration for the resource  azurerm_private_endpoint as below to create the private_endpoint in the Australia east region:

resource "azurerm_private_endpoint" "static_web_app_endpt" {

  name  =  "testswa-pe" #name of the private endpoint
  location = "Australia East" #location of private endpoint
  resource_group_name =  "test-rg" #name of the rg where azurerm_static_web_app is listed
  subnet_id = azurerm_subnet.endpoint.id 
  private_service_connection {
    name                            = "testswarg-psc" #name of private service connection
    private_connection_resource_id  = azurerm_static_web_app.static_site.id  
    subresource_names = ["staticSites"]
    is_manual_connection            = false
}
