Hi Arthur,
I forgot to mention that you need to look for it in the browser dev tools, network tab. As an administrator, I'm receiving an e-mail each time someone triggers the issue. There's no visible exception in the browser other than a failed GET request which you can find in the network tab. I was able to reproduce the same error on the demo site (demo.netbox.dev).

  • Error Internal Server Error: /api/dcim/racks/{{rack}}/elevation/ also happens, when you edit a Device with assigned Rack. When you click on changing a Site (then a Rack is changed to None) I will receive an e-mail from NetBox with message:
Internal Server Error: /api/dcim/racks/{{rack}}/elevation/

ValueError at /api/dcim/racks/{{rack}}/elevation/
Field 'id' expected a number but got '{{rack}}'.
  • I suppose this error happens during API call to racks while selecting objects in the UI
  • Using NetBox v4.0.6
