help on my loop issue

[Mgsz]

pretty new to Ansible, here is my problem, could anyone help?

Thanks!!

within my playbook, I have following tasks:

- debug: msg="{{ dev_interfaces[0].name }}"

- name: debug message interface name
  debug: var=item
  with_items: dev_interfaces

When run the playbook:

TASK [debug msg={{ dev_interfaces[0].name }}] ****************************
ok: [10.3.146.113] => {
    "changed": false,
    "msg": "Ethernet0"
}

TASK [debug message interface name] **********************************
fatal: [10.3.146.113]: FAILED! => {"failed": true, "msg": "ERROR! dict object has no element {u'subnet': u'10.0.0.0/31', u'peer_addr': u'10.0.0.1', u'name': u'Ethernet0', u'mask': u'255.255.255.254', u'prefixlen': 31, u'addr': u'10.0.0.0'}"}
