please, help with error :((

[Cornus]

I created a character and uploaded it to steam. At first everything was fine, but then people began to talk about some kind of error coming out, and when I myself go to play for him, everything is fine with me. How to fix it?
(sorry for bad english, I use a translator)

local function OnUpdate(inst, dt)
    if (inst.components.sanity.current < 75) or (inst.components.sanity.current = nil) then
        inst.components.playervision:ForceNightVision(true)
        inst.components.playervision:SetCustomCCTable(true and {} or nil)
    else
        inst.components.playervision:ForceNightVision(false)
    end
end
