Steps to Reproduce

I want to install NetBox Topology Views

docker compose exec -it -u root netbox /usr/bin/bash
source /opt/netbox/venv/bin/activate
uv pip install netbox-topology-views
Add plugins configuration at the /etc/netbox/config/extra.py(Followed the format in the file example)

## Enable installed plugins. Add the name of each plugin to the list.
# from netbox.configuration.configuration import PLUGINS
# PLUGINS.append('my_plugin')

PLUGINS.append('netbox_topology_views')

## Plugins configuration settings. These settings are used by various plugins that the user may have installed.
## Each key in the dictionary is the name of an installed plugin and its value is a dictionary of settings.
# from netbox.configuration.configuration import PLUGINS_CONFIG
# PLUGINS_CONFIG['my_plugin'] = {
#   'foo': 'bar',
#   'buzz': 'bazz'
# }

PLUGINS_CONFIG['netbox_topology_views'] = { 
    'static_image_directory': 'netbox_topology_views/img',
    'allow_coordinates_saving': True,
    'always_save_coordinates': True
}

python3 /opt/netbox/netbox/manage.py migrate

Get the error:
