• Workaround
  touch /etc/config/firewall

Expected behaviour

get https://192.168.1.1/cgi-bin/luci/admin/network/dhcp
returns correct config settings without firewall packages installed.

dhcp.js load uci firewall

luci/modules/luci-mod-network/htdocs/luci-static/resources/view/network/dhcp.js

Line 281 in edc352e

uci.load('firewall')

for ipset in

luci/modules/luci-mod-network/htdocs/luci-static/resources/view/network/dhcp.js

Line 1135 in edc352e

uci.sections('firewall', 'ipset', function(s) {

This should be optional.

Steps to reproduce

rm /etc/config/firewall
get dhcp config site
get https://192.168.1.1/cgi-bin/luci/admin/network/dhcp
