VM Interface: Error Fetching Options for field 'untagged_vlan'

[t8simon]

NetBox version

v3.3.4

Python version

3.10

Steps to Reproduce

1. Create a VM and assign it only to a Site, not a Cluster
2. Create a Interface for the VM
3. Scroll down, select 802.1Q Mode: "Access"
4. Open the "Untagged VLAN" Dropdown

Expected Behavior

A short error message with a hint on the error. Or the possibility to select a VLAN when no Cluster is assigned to the VM (if that makes any sense).

Observed Behavior

A very long error message with visible html code appears.
