Start at specification/web/resource-manager/Microsoft.Web/stable/2021-03-01/WebApps.json near the WebApps_ListSlotConfigurationNames operation. Compare its GET response with the Microsoft.Web/sites/config resource reference and verify the modeled name is slotConfigNames and the id is present; done when the round-trip check no longer reports a missing resource id across the affected API versions.
