Terraform destroy cannot remove items provisioned by this Template Deployment

[ptsk5]

Hi,

I used a part of this ARM template in my approach to provision the ARO cluster with terraform and it works. The issue is when I try to terraform destroy that I receive an error related to these two role assignments.

{
            "type": "Microsoft.Network/virtualNetworks/providers/roleAssignments",
            "apiVersion": "2018-09-01-preview",
            "name": "[concat(parameters('clusterVnetName'), '/Microsoft.Authorization/', guid(resourceGroup().id, deployment().name, parameters('aadObjectId')))]",
            "properties": {
                "roleDefinitionId": "[variables('contribRole')]",
                "principalId":"[parameters('aadObjectId')]"
            }
        },
        {
            "type": "Microsoft.Network/virtualNetworks/providers/roleAssignments",
            "apiVersion": "2018-09-01-preview",
            "name": "[concat(parameters('clusterVnetName'), '/Microsoft.Authorization/', guid(resourceGroup().id, deployment().name, parameters('rpObjectId')))]",
            "properties": {
                "roleDefinitionId": "[variables('contribRole')]",
                "principalId":"[parameters('rpObjectId')]"
            }
        },

The error is:

Error: removing items provisioned by this Template Deployment: deleting Nested Resource "/subscriptions/<my_subscription>/resourceGroups/<my_rg>/providers/Microsoft.Network/virtualNetworks/<my_vnet>/providers/Microsoft.Authorization/roleAssignments/4b7d3178-1fa2-5281-8e6a-7746cb4e36ef": resources.Client#DeleteByID: Failure sending request: StatusCode=0 -- Original Error: Code="NoRegisteredProviderFound" Message="No registered resource provider found for location 'westeurope' and API version '2021-05-01' for type 'roleAssignments'.

The supported locations are ''."

Two things, I would like to point out:

• in the template, I see the API version is 2018-09-01-preview (which is also included in the list of supported api-versions in the error)... Why does the error mention a different API version 2021-05-01...
• I have the Microsoft.Authorization provider registered.

Please, do you have any idea what is wrong?

Thanks a lot.
