Yesterday we notices that the arm-template that we are using to create a new app service slot was not able to copy settings from prod-slot to staging-slot. Api version "2016-08-01".
To copy the settings we use a script for type: "Microsoft.Web/sites"
"siteConfig": "[reference(resourceId('Microsoft.Web/Sites', variables('cdWebAppNameTidy')), variables('webApiVersion')).siteConfig]"
I also notice that when I export a template for the prod app-service, siteConfig is empty. Though, the settings are visible in another section "Microsoft.Web/sites/config"...
Anybody know if something thas changed in the api or what is going on?
