NetBox Community

NetBox Version

v4.4.1

Python Version

3.10

Steps to Reproduce

  1. Create a custom field of type URL for object class DCIM->Device
  2. Edit a device and enter an URL with a custom scheme like cdb://byname/classname/...

Expected Behavior

The edit gets saved and I have a clickable URL.
All properly formatted URL schemes should be accepted, not only HTTP, HTTPS etc.

Observed Behavior

An error message is displayed:

If I replace cdb:// with http:// the edit gets saved, so the error message is only triggered by the scheme part and not the rest of the URL.
