Darktable 4.8.0
luajson 1.3.4

[vitaly-zdanevich]

Solved locally by copy https://github.com/harningt/luajson/blob/master/lua/json/decode/util.lua to /usr/share/lua/5.4/json/decode/util.lua

So this is a dependency issue harningt/luajson#51

@vitaly-zdanevich FYI, I just pushed luajson-1.3.4-r1 in Gentoo with this fix. In future, please feel free to file a Gentoo bug letting us know we need a backport.
