gluon-web-wifi-config: fetching information returns Internal Server Error

[blocktrron]

Bug report

What is the problem?
WiFi config is not displayed when accessing the WiFi tab in advanced setup mode.
Instead only a box with the following content is displayed:

Failed to execute dispatcher target for entry '/admin/wifi-config'.
The called action terminated with an exception:
/usr/lib/lua/simple-uci.lua:22: attempt to index local 'c' (a nil value)

Viewing the recent commits for lua-simple-uci, whis commit could be interesting: freifunk-gluon/packages@cf0619a#diff-951cae4df37f09f01930d67db0316037

What is the expected behaviour?
WiFi config should be visible.

Gluon Version:
recent master

Site Configuration:

After changing the Line https://github.com/freifunk-gluon/gluon/blob/master/package/gluon-web-wifi-config/luasrc/lib/gluon/config-mode/model/admin/wifi-config.lua#L139 from

ht.default = uci.get('gluon', 'wireless', 'outdoor_' .. radio .. '_htmode') or 'default'

to

ht.default = uci:get('gluon', 'wireless', 'outdoor_' .. radio .. '_htmode') or 'default'

the WiFi configuration is displayed as expected again.

@NeoRaider was that the only issue or does lua-simple-uci have a bug here?

The bug is in wifi-config, simple-uci is working as expected.

@NeoRaider thanks for the fix!
