LUA weather error?

[Squid Milk]

hey gamers first post here about a LUA error I have, wasn't sure if this is a mod error or a game bug but here's the error log:

[02:32:18]: [string "scripts/components/inventory.lua"]:682: attempt to index field 'isexternallyinsulated' (a nil value)
LUA ERROR stack traceback:
    scripts/components/inventory.lua:682 in (method) IsInsulated (Lua) <675-683>
    scripts/components/playerlightningtarget.lua:3 in (field) onstrikefn (Lua) <1-19>
    scripts/components/playerlightningtarget.lua:41 in (method) DoStrike (Lua) <39-43>

    scripts/components/weather.lua:932 in (method) OnUpdate (Lua) <773-941>
    scripts/update.lua:262 in () ? (Lua) <224-298>

it happened basically not long after hearing a lightning strike which kinda makes sense looking at this code (i have no experience with code) but got up to about day 33 with my BF on an online server with heavy rain and lightning. we have like 8 mods enabled maybe but they are just common ones that are frequently updated and used (more inventory, quick pick, etc)

any help would be great, thanks :^)

You are using an old 40 inventory slot mod.
