The error was: 'dict object' has no attribute 'prefix'\n\n when my my dict does include a value - 'prefix'

[marky2376]

SUMMARY

I am creating a new prefix with the module netbox.netbox.netbox_prefix. Registering the netbox dict as a variable then trying to filter a value in another task.

"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'prefix'\n\nThe error appears to be in '/tmp/bwrap_1661_kmw00u2r/awx_1661_4u8n4f49/project/ReserveIPNetbox.yml': line 66, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n - name: "Set fact for Prefix"\n ^ here\n",
"_ansible_no_log": false

STEPS TO REPRODUCE

• name: Get a new prefix when circuit is South Carolina
  netbox.netbox.netbox_prefix:
  netbox_url: http://netbox.truvista.net:8085
  validate_certs: False
  netbox_token:
  data:
  parent: "206.74.x.0/24"
  prefix_length: "{{ prefix_length }}"
  description: "{{ c_description }}"
  state: present
  first_available: yes
  register: c_prefix
  when: location == "South_Carolina"

• name: "Set fact for Prefix"
  set_fact:
  prefix2: "{{ c_prefix['prefix'] }}"
  when: (location == "South_Carolina" or location == "Georgia")

EXPECTED RESULTS

The variable should be set as just the prefix value of the dict. This works with exact same logic on the netbox.netbox.netbox_ip_address module, so not sure what is different about these dicts. I get a similar problem when I do an nblookup. It doesn't seem to find the value so it prints all my prefixes.

This is an example of the prefix dict:

{
"key": 7199,
"value": {
"created": "2019-09-27",
"custom_fields": {},
"description": "DSL MGMT Pool",
"display": "10.8.0.0/16",
"family": {
"label": "IPv4",
"value": 4
},
"id": 7199,
"is_pool": false,
"last_updated": "2019-09-27T19:40:49.367624Z",
"prefix": "10.8.0.0/16",
"role": null,
"site": null,
"status": {
"label": "Active",
"value": "active"
},
"tags": [],
"tenant": null,
"url": "http://netbox.truvista.net:8085/api/ipam/prefixes/7199/",
"vlan": null,
"vrf": null
}
ACTUAL RESULTS

"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'prefix'\n\nThe error appears to be in '/tmp/bwrap_1661_kmw00u2r/awx_1661_4u8n4f49/project/ReserveIPNetbox.yml': line 66, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n    - name: \"Set fact for Prefix\"\n      ^ here\n",
"_ansible_no_log": false

When I just try to print the registered variable from netbox_prefix, I get:

ok: [localhost] => {
"<class 'dict'>": "VARIABLE IS NOT DEFINED!"

It works for me, but its hard to troubleshoot your formatting is not using code blocks.

Here is my example:

    - name: "TEST GRAB FIRT_AVAILBLE PREFIX"
      netbox.netbox.netbox_prefix:
        netbox_url: "{{ netbox_api_url }}"
        netbox_token: "{{ netbox_token }}"
        validate_certs: false
        data:
          parent: 10.112.0.0/15
          prefix_length: 24
          description: test
        state: present
        first_available: yes
      register: test

    - name: "DEBUG OUTPUT"
      ansible.builtin.debug:
        var: test
