E750 Mudi - luci error, missing 'luci.cbi'

Updated via https://fw.gl-inet.com/firmware/e750/release/openwrt-e750-3.211-1227.tar
Installed luci (why isn’t this there by default any more? why so little free space on such an expensive device?)

Navigated to http://192.168.8.1/cgi-bin/luci/admin/system/MCU-interface

Got the following error

/usr/lib/lua/luci/dispatcher.lua:1334: module 'luci.cbi' not found:

I don’t know what is wrong with the luci interface.

But for mcu setup, you can use the default UI

You can try installing luci-compat

OK, where should I report the bug?

You aleady did. Developer will remove that entry.
