Deployment Type

Self-hosted

NetBox Version

v4.3.1

Python Version

3.12

Steps to Reproduce

  1. Create a custom script in Netbox 4.2
  2. Delete the script file but do not delete the script from Netbox
  3. Upgrade to 4.3.1
  4. Notice that the script name is missing in the UI and the netbox.data_backends log shows Failed to load script: update_telegraf error: [Errno 2] No such file or directory: '/opt/netbox/netbox/scripts/update_telegraf.py' at debug level
  5. Try to delete the script from the webpage

Expected Behavior

I should be able to delete the script even though the file is missing

Observed Behavior

Internal Server Error: /extras/script-modules/90/delete/

Thank you for opening a bug report. I was unable to reproduce the reported behavior on upgrading NetBox v4.2.9 to v4.3.1. Please re-confirm the reported behavior on the current stable release and adjust your post above as necessary. Remember to provide detailed steps that someone else can follow using a clean installation of NetBox to reproduce the issue. Remember to include the steps taken to create any initial objects or other data.
