I tried to deploy an Windows VM Scale Set with custom Image from a shared Image Gallery. Version of azurerem is 2.8.
The deployment works if i specify a marketplace image like:
publisher = "MicrosoftWindowsServer" offer = "WindowsServer" sku = "2016-Datacenter-Server-Core" version = "latest"
If I specify a custom image
id = data.azurerm_shared_image.vmss2019iis.id
It fails with the message that source_image_id is not expected here.
Is this a known issue?
PS: the id works, verified it in the output
