Versions: Terraform v0.13.5 + provider registry.terraform.io/aztfmod/azurecaf v1.1.8 + provider registry.terraform.io/hashicorp/azurerm v2.39.0 Scenario: - 1 VWAN containing 2 HUB's. - 2 ExpressRouters created - 3 Expressroute Gateways created (azurerm_express_route_gateway) when trying to "Circuit connect" using the azurerm_virtual_network_gateway_connection I get the following error: Error: Error Creating/Updating AzureRM Virtual Network Gateway Connection "to_amsterdam" (Resource Group "rg-{}"): network.VirtualNetworkGatewayConnectionsClient#CreateOrUpdate: Failure sending request: StatusCode=400 -- Original Error: Code="InvalidRequestFormat" Message="Cannot parse the request."

But this resource needs a VNET, subnet and Public IP (ip_configuration block) which should not be needed. When making the "Circuit connection" in the portal this configuration is not needed. Please advice. Ray
