Tool can't parse the Service level scope defined in Azure API Management

I am trying this tool to import configuration for a vanilla Azure API Management instance. When I try to import it into Terraform code it throws an error. This error is related to the built-in subscription for Service scope called "Built-in all-access subscription". Seems like the tool is not able to interpret this scope.

`Failed to import /subscriptions/0000-0000-0000-0000-0000/resourceGroups/resource-group-name/providers/Microsoft.ApiManagement/service/apim-instance-name/subscriptions/master as azurerm_api_management_subscription.res-33: exit status 1`

`Error: parsing scope into product/ api id "/subscriptions/0000-0000-0000-0000-0000/resourceGroups/resource-group-name/providers/Microsoft.ApiManagement/service/apim-instance-name/": ID was missing the `apis` element`
