NetBox version

v4.1.0

Python version

3.11

Steps to Reproduce

# path/to/inventory/01_netbox.yml
---
plugin: netbox.netbox.nb_inventory

api_endpoint: http://A.B.C.D/netbox
token: 1234567890123456789012345678901234567890
validate_certs: false
config_context: false

Expected Behavior

Debian Bookworm 12.7 up to date:

The inventory works witch netbox v4.0.11 and ansible_modules v3.19.1 (despite the message Collection netbox.netbox does not support Ansible version 2.14.16).

After update to netbox v4.1.0 the error as below and ansible_module v3.20.0 brought no change.

Observed Behavior
