Steps to Reproduce

task from ansible:

- name: Create device roles
  netbox.netbox.netbox_device_role:
    netbox_url: "{{ netbox_url }}"
    netbox_token: "{{ netbox_token }}"
    data:
      name: "{{ role_type }}"
      slug: "{{ role_type }}"
      color: FFFFFF
    state: present

Expected Behavior

I expect device role slug to be created with uppercase symbols. I tried slug: "{{ role_type | upper }}"

Observed Behavior

device role slug is always created with lowercase symbols. For this reason ansible not picked up my group_vars. I have to change slug of device role manually and then I see the variables

I am lost, names allow upper case and spaces, slugs do not in netbox.
