CAF Foundation landing zone - deployment error

[manavibanerjee]

Describe the bug
While deploying caf-terraform-landingzones , I get an error that the resources already exit.
Error: A resource with the ID "/subscriptions/18ab9f36-e50d-482f-919a-bbfb490d4f4c/providers/Microsoft.Authorization/policyAssignments/vm_auto_monitor" already exists - to be managed via Terraform this resource needs to be imported into the State. Please see the resource documentation for "azurerm_policy_assignment" for more information.

47: resource "azurerm_monitor_log_profile" "subscription" {

Error on or near line 483: Error running terraform apply; exiting with status 2001

I have checked my subscription and nothing was deployed in the southeastasia region and I had only resources deployed by preparation steps which are from:
rover /tf/caf/landingzones/launchpad apply -launchpad
Subscription resources Status prior to CAF foundation landing zone deployment

Why does the error report that vm_auto_monitor, vm_no_managed_disks and logprofiles already exists?
I have destroyed the whole deployment and started fresh as well but it says the same.

please help.

thanks,
Manavi

there as been a previous run of the caf_foundations landing zone where the logprofile (subscription/audit policy) and policy assignment were not successfully destroyed, you need to manually remove the objects.
