Can anyone assist me with the issue I am having when I am trying to deploy multiple resources via Arm templates?
Since I have resources which are scoped on different levels, I am using nested Arm template deployment. I am trying to create new resource group which is scoped on subscription level and two resources, namely: Log Analytics workspace and Azure Sentinel which are scoped on resource group level. But when I run Powershell command New-AzSubscriptionDeployment I am getting an error, which is stated below:
New-AzDeployment: 3:20:48 PM - Error: Code=InvalidTemplate; Message=Deployment template validation failed: 'The resource 'Microsoft.Resources/resourceGroups/duo' is not defined in the template. Please see https://aka.ms/arm-template for usage details.'.
New-AzDeployment: The deployment validation failed
My template is included below. I would really appreciate anyone’s help.
