When creating a wireguard endpoint, this message was shown after I used a space in the name: 'please specify a valid address (IPv4/IPv6) or hostname'

1. Go to 'VPN - Wireguard'
2. Create an endpoint
3. Use a space in the name
4. Click 'Save'

Error message like 'No spaces allowed' or 'Use only alfanumeric characters' or similar.
