So I'm really new to ARM templates and for my first template I'm trying to create one that asks some questions and ultimately creates a new subnet and an NSG if required and then a VM and all it's components.
The template I've pasted below works perfectly if I select 'Yes' for both the 'Create New Subnet' and 'Create New NSG' questions. If I select 'No' I get an error saying:
The template resource 'dev-vnet/' for type 'Microsoft.WindowsAzure.ResourceStack.Frontdoor.Common.Entities.TemplateGenericProperty`1[System.String]' at line '1' and column '306' has incorrect segment lengths. A nested resource type must have identical number of segments as its resource name. A root resource type must have segment length one greater than its resource name.
I have no idea what this means and was hoping that answering 'No' would just skip the Subnet and NSG creation and continue, but it doesn't.
Could anyone help me resolve the issue please?
