Steps to Reproduce

Run the following playbook on a netbox instance.

- name: Playbook
  hosts: 127.0.0.1
  gather_facts: false
  become: false

  tasks:
    - name: Create one custom field
      netbox.netbox.netbox_custom_field:
        netbox_url: NETBOX_URI
        netbox_token: NETBOX_TOKEN
        data:
          choices:
            - one
            - two
          content_types:
            - ipam.ipaddress
          default: one
          description: description
          filter_logic: loose
          group_name: group
          label: dummy
          name: dummy
          required: false
          search_weight: 1
          type: select
          ui_visibility: read-write
        state: present

This is what happens:

PLAY [Playbook :: Install/Upgrade Docker Containers for Netbox] *****************************************************************************************************************************

TASK [Create one custom field] **************************************************************************************************************************************************************
fatal: [localhost]: FAILED! => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python3.11"}, "changed": false, "msg": "{\"error\": \"'NoneType' object has no attribute 'values'\", \"exception\": \"AttributeError\", \"netbox_version\": \"3.7.5\", \"python_version\": \"3.11.4\"}"}

PLAY RECAP **********************************************************************************************************************************************************************************
localhost                  : ok=0    changed=0    unreachable=0    failed=1    skipped=0    rescued=0    ignored=0 

Expected Behavior

The custom_field should have been created.

Observed Behavior

An AttributeError exception was raised.

I believe we have merged code that fixes this, but we have not cut a new release yet.

This works in 3.19.1. You must split it to first create choice set using netbox_custom_field_choice_set and then create the custom field.
