ValueError: Unable to configure handler 'netbox_auth_log'

Hello,

I am trying to add logging to Netbox but i got those error:

return _bootstrap._gcd_import(name[level:], package, level)

The configuration that i use is this:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'netbox_auth_log': {
            'level': 'DEBUG',
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': '/opt/netbox/logs/django-ldap-debug.log',
            'maxBytes': 1024 * 500,
            'backupCount': 5,
        },
    },
    'loggers': {
        'django_auth_ldap': {
            'handlers': ['netbox_auth_log'],
            'level': 'DEBUG',
        },
    },
}

I tried also the default one in the documentation but i got the some errors.
If i remove the logging configuration Netbox start without issue again:

LOGGING = {}

Does the file /opt/netbox/logs/django-ldap-debug.log exist, and does the NetBxox system user have write access to it? With the file in place, your logging config seems to work fine for me.

Thanks Jeremy. the NetBox system user write access was missing.
I add and the application start well.

It's not a very helpful error, is it? 🤔 Glad you got it sorted!
