Error: Host can open container but Client crashes when opening it

[blazerdrive09]

Currently, I am developing a custom mod for Don't Starve together. It is a composter that increases the rate at which things rot inside. I was able to successfully make the a placable structure using animations from another steam mod temporarily just to see if it works before i make my own designs and animations for the composter. The host is able to open it as well and put items in it and it also successfully increases the rate at which things compost inside of it. However, if another person joins the server with the mod installed, and tries to open the composter, or any composter no matter who made it, the client crashes while the host is still able to open it and the server is still able to run. The error seems to be due to a widget or something of that nature I can include a screenshot later. Here is the prefab for the composter:

 

require "prefabutil"

local assets=
{
    Asset("ANIM", "anim/cellar.zip"),
    Asset("ANIM", "anim/ui_chest_3x3.zip"),
}
local prefabs =
{
    "collapse_small",
}

local function onopen(inst) 
     
    inst.SoundEmitter:PlaySound("dontstarve/wilson/chest_open")        
        inst.AnimState:PlayAnimation("open")
end 

local function onclose(inst) 
    inst.AnimState:PlayAnimation("closed")
    inst.SoundEmitter:PlaySound("dontstarve/wilson/chest_close")        
end 

local function onhammered(inst, worker)
    inst.components.lootdropper:DropLoot()
    inst.components.container:DropEverything()
    local fx = SpawnPrefab("collapse_small")
    fx.Transform:SetPosition(inst.Transform:GetWorldPosition())
    fx:SetMaterial("wood")
    inst:Remove()
end

local function onhit(inst, worker)
    inst.AnimState:PlayAnimation("hit")
    inst.components.container:DropEverything()
    inst.AnimState:PushAnimation("closed", false)
    inst.components.container:Close()
end

local function onbuilt(inst)
    inst.AnimState:PlayAnimation("place")
    inst.AnimState:PushAnimation("closed")    
end

local function itemtest(inst, item, slot)
    return (item.components.edible and item.components.perishable) or item.prefab == "spoiled_food" or item.prefab == "rottenegg"
end

local function onsave(inst, data)
    if inst:HasTag("burnt") or (inst.components.burnable ~= nil and inst.components.burnable:IsBurning()) then
        data.burnt = true
    end
end

local function onload(inst, data)
    if data ~= nil and data.burnt and inst.components.burnable then
        inst.components.burnable.onburnt(inst)
    end
end

local function fn(Sim)
    local inst = CreateEntity()

    inst.entity:AddTransform()
    inst.entity:AddAnimState()
    inst.entity:AddSoundEmitter()
    inst.entity:AddNetwork()

    local minimap = inst.entity:AddMiniMapEntity()
    minimap:SetIcon( "cellar.tex" )
    
    MakeObstaclePhysics(inst, 1.0)    
    inst:AddTag("composter")
    inst:AddTag("structure")
    inst.AnimState:SetBank("cellar")
    inst.AnimState:SetBuild("cellar")
    inst.AnimState:PlayAnimation("closed", true)
    
    MakeSnowCoveredPristine(inst)

    inst.entity:SetPristine()
    
    if not TheWorld.ismastersim then
        return inst
    end
    
    inst:AddComponent("inspectable")
    inst:AddComponent("container")
    inst.components.container:WidgetSetup("icebox")
    
    inst.components.container.onopenfn = onopen
    inst.components.container.onclosefn = onclose   

    inst:AddComponent("lootdropper")

    inst:AddComponent("workable")
    inst.components.workable:SetWorkAction(ACTIONS.HAMMER)
    inst.components.workable:SetWorkLeft(1)
    inst.components.workable:SetOnFinishCallback(onhammered)
    inst.components.workable:SetOnWorkCallback(onhit)
    
    AddHauntableDropItemOrWork(inst)
    MakeSnowCovered(inst)
    
    inst.OnSave = onsave 
    inst.OnLoad = onload    
    

    return inst
end

return Prefab( "common/cellar", fn, assets),
    MakePlacer("common/cellar_placer", "cellar", "cellar", "closed")

That's because the "icebox" widget setup doesn't propagate to clients.

Clients try to use the widget for "cellar" and they don't find any.

Add this line so clients can setup the correct widget:

if not TheWorld.ismastersim then
	inst.OnEntityReplicated = function(inst) inst.replica.container:WidgetSetup("icebox") end
	return inst
end

Thanks! It worked, I knew it had something to due with the replica that needs to made for the clients but I couldn't figure out what was causing the problem or what needed to be done or how.
