Here, you appear to be trying to get the 'id' attribute of 'subnets'. It
doesn't have one, because it's a list.
var: "subnet_facts.results | map(attribute='subnets') | flatten |
map(attribute='id') | list"
(The `flatten` filter is new in Ansible 2.5; on older versions you'd need
to use the `flatten` lookup.)
