by applying azurerm_application_gateway, request_routing_rule with the mandatory Flag Priority i got the following Error by the Azure API:
Resource Group “”): network.ApplicationGatewaysClient#CreateOrUpdate: Failure sending request: StatusCode=400 – Original Error: Code=“ApplicationGatewayFeatureCannotBeEnabledForSelectedSku” Message=“Application Gateway xxxx does not support Priority for the selected SKU tier Standard. Supported SKU tiers are Standard_v2,WAF_v2.” Details=
but I want to use SKU Standard, because Standard_V2 is more expensive.
