'NoneType' object has no attribute 'lower'

[i-pushkin]

When attempting to retrieve data from the cluster, the following error is displayed

<class 'AttributeError'>

'NoneType' object has no attribute 'lower'

Python version: 3.10.10
NetBox version: 3.4.7

It is not quite clear how to diagnose such an error

Firstly, you'll need to say exactly what you were doing when you got that error. In particular: what path was in the browser URL bar for the previous page, and what did you click within that page?

Secondly, you'll need to capture the full backtrace. You can do this by setting ADMINS and EMAIL in configuration.py (in which case it will be mailed out to you), or by setting DEBUG=True, in which case you'll be able to see it in the web interface.

Thank you for the tip. Here is the result:

Exception Type: AttributeError at /plugins/proxbox/full_update/
Exception Value: 'NoneType' object has no attribute 'lower'

My guess is that the problem is that my netbox installation already has data that is in conflict.

[candlerb]

The exception is a bug in a plugin (netbox_proxbox), so you need to either disable that plugin, or raise your problem with the plugin author.

Sorry, I made a mistake and wrote the question in the wrong repository. )
