Fail to create azurerm_virtual_network_gateway

Hi, I am try to run the code in new-environment but I am getting "Basic IP configuration for ExpressRoute Virtual Network Gateways is not supported". According to the doc on azurerm_virtual_network_gateway, To build a UltraPerformance ExpressRoute Virtual Network gateway, the associated Public IP needs to be SKU "Basic" not "Standard". The following is what I get from TF apply:

│ Error: Creating/Updating Virtual Network Gateway: (Name "InterConnectVNETGateway" / Resource Group "azure_oci_test_resources"): network.VirtualNetworkGatewaysClient#CreateOrUpdate: Failure sending request: StatusCode=400 -- Original Error: Code="PublicIpWithBasicSkuNotAllowedOnExpressRouteGateways" Message="Basic IP configuration for ExpressRoute Virtual Network Gateways is not supported. Please create and associate a Standard IP. /subscriptions/dfec75b7-da3b-4c07-ad4d-b56b9e7dabdb/resourceGroups/azure_oci_test_resources/providers/Microsoft.Network/virtualNetworkGateways/InterConnectVNETGateway" Details=[]
