Answer 1

Message=The client 'XXXXXXXXXXXXXXX' with object id 'XXXXXXXXXXXX' does not have authorization to perform action 'Microsoft.Resources/subscriptions/resourcegroups/write' over scope '/subscriptions/XXXXXXXXXX/resourcegroups/Zimmergren.ARM.ResourceGroupDemo-123'.

The reason you're getting this error is because the Service Pricipal you created does not have permission to perform Create Resource Group operation in your Azure Subscription.

What you would need to do is assign a role to this Service Principal that has permission to perform this operation. To start with, you can assign Contributor role at the Subscription level to this Service Principal .

You can do it through Azure Portal , PowerShell Cmdlets or CLI Tools . You may find this link helpful in doing this through Azure Portal: https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-create-service-principal-portal#assign-application-to-role .
