making a custom container widget makes every other container crash

[Mentos]

i've been trying to add a custom widget for a custom backpack item, i managed to get it to work for the custom backpack, but it makes every container that is not my custom backpack crash when used.

 

This is the code i have in my modmain

local containers = require "containers"

local params = {}

containers.params = params

function containers.widgetsetup(container, prefab, data)
    local t = data or params[prefab or container.inst.prefab]
    if t ~= nil then
        for k, v in pairs(t) do
            container[k] = v
        end
        container:SetNumSlots(container.widget.slotpos ~= nil and #container.widget.slotpos or 0)
    end
end

params.whiskpack =
{
    widget =
    {
        slotpos = {},
        animbank = "ui_krampusbag_2x8",
        animbuild = "ui_krampusbag_2x8",
        pos = Vector3(-5, -120, 0),
    },
    issidewidget = true,
    type = "pack",
    openlimit = 1,
}

for y = 0, 6 do
    table.insert(params.whiskpack.widget.slotpos, Vector3(-162, -75 * y + 240, 0))
    table.insert(params.whiskpack.widget.slotpos, Vector3(-162 + 75, -75 * y + 240, 0))
end

function params.whiskpack.itemtestfn(container, item, slot)
    return item:HasTag("spider") or item:HasTag("cavedweller") or item:HasTag("spider_warrior")
end

params.whiskpack.priorityfn = params.whiskpack.itemtestfn

If i remove my custom widget everything works fine, so i am clueless as to why it's crashing.

Any help would be appreciated

why you erase every other container and override the widgetsetup function?

oh i see what u mean. widgets are rly confusing to me sorry lol

I've tried to go thru it one more time and looked at some other mods

local params={} 

params.whiskpack =
{
    widget =
    {
        slotpos = {},
        animbank = "ui_krampusbag_2x8",
        animbuild = "ui_krampusbag_2x8",
        pos = GLOBAL.Vector3(-5, -120, 0),
    },
    issidewidget = true,
    type = "pack",
    openlimit = 1,
}

for y = 0, 6 do
    table.insert(params.whiskpack.widget.slotpos, GLOBAL.Vector3(-162, -75 * y + 240, 0))
    table.insert(params.whiskpack.widget.slotpos, GLOBAL.Vector3(-162 + 75, -75 * y + 240, 0))
end

function params.whiskpack.itemtestfn(container, item, slot)
    return item:HasTag("spider") or item:HasTag("cavedweller") or item:HasTag("spider_warrior")
end

params.whiskpack.priorityfn = params.whiskpack.itemtestfn

local containers = GLOBAL.require "containers"
containers.MAXITEMSLOTS = math.max(containers.MAXITEMSLOTS, params.whiskpack.widget.slotpos ~= nil and #params.whiskpack.widget.slotpos or 0)
local old_widgetsetup = containers.widgetsetup
function containers.widgetsetup(container, prefab, data)
        local pref = prefab or container.inst.prefab
        if pref == "whiskpack" then
                local t = params[pref]
                if t ~= nil then
                        for k, v in pairs(t) do
                                container[k] = v
                        end
                        container:SetNumSlots(container.widget.slotpos ~= nil and #container.widget.slotpos or 0)
                end
        else
            return old_widgetsetup(container, prefab)
    end
end

i think i managed to fix it, at least as far as i can tell
