Steps to reproduce

Idea is to use one ww-instance to host two different (some more later) clusters residing in different subnet and VLANs.
I followed the description on https://warewulf.org/docs/v4.5.x/contents/setup.html#multiple-networks
after heading 'multiple networks'.

1. created the dummy entries for each subnet
2. ran wwctl overlay edit host etc/dhcpd.conf.ww
   Removed the section:

{{- if and .Network .Netmask }}
subnet {{.Network}} netmask {{.Netmask}} {
max-lease-time 120;
{{- if and .Dhcp.RangeStart .Dhcp.RangeEnd }}
range {{.Dhcp.RangeStart}} {{.Dhcp.RangeEnd}};
{{- end }}
{{- if .Ipaddr }}
next-server {{.Ipaddr}};
{{- end }}
}
{{- end }}

and added:
{{/* multiple networks */}}
{{- range $node := $.AllNodes}}
{{- if eq $node.Id.Get "deliverynet" }}
{{- range $netname, $netdev := $node.NetDevs}}

network {{ $netname }}

subnet {{$netdev.Tags.network.Get}} netmask {{$netdev.Netmask.Get}} {
max-lease-time 120;
range {{$netdev.Tags.dynstart.Get}} {{$netdev.Tags.dynend.Get}};
next-server {{$netdev.Ipaddr.Get}};
}
{{- end }}
{{- end }}
{{- end }}

3. saving and 'compiling' shows the warning (error):
   [root@ ~]# wwctl configure dhcp
   Building overlay for mpshead01: host
   WARN : host overlay could not be built: failed to build overlay image directory: failed to render template /install/lib/warewulf/overlays/host/rootfs/etc/dhcp/dhcpd.conf.ww: could not execute template: template: dhcpd.conf.ww:54:15: executing "dhcpd.conf.ww" at <$node.Id.Get>: can't evaluate field Get in type string
   Enabling and restarting the DHCP services

--> although just a warning, a new dhcpd.conf isn't created.

Additionally the line to be added in dhcpd.conf for each non-warewalf node subnet is

option routers 10.233.50.1;

otherwise the iPXE boot stops in my environment after the DHPACK - action on the server node.

The pedestrian approach adding the subnet manually into the template + the option - router line works.

Error message
