$interface_fact_name, value is empty

Problem:
foreman-installer ,–foreman-proxy-dns-interface=eno2
if it is set to eno2 getting error :
Evaluation Error: Error while evaluating a Function Call, Could not get the ip address from fact ipaddress_
at /usr/share/foreman-installer/modules/foreman_proxy/manifests/proxydns.pp

Expected outcome:
variable value of $interface_fact_name = regsubst($foreman_proxy::dhcp_interface, ‘[.:]’, ‘_’)
in /usr/share/foreman-installer/modules/foreman_proxy/manifests/proxydns.pp
should be eno2
however currently it is empty…
if a manually set it to eno2 it works…
so the value
