尝试索引布尔值（本地“target”）

我已经尝试了不同的方法来解决这个问题，但完全不理解。我已经尝试过以每种可能的方式修复代码，但仍然没有成功。

RegisterServerEvent('housing:attemptsale')
AddEventHandler('housing:attemptsale',
function(args,price,hid,model)
    local src = source
    local user = exports["np-base"]:getModule("Player"):GetUser(src)
    local char = user:getCurrentCharacter()
    local target = exports["np-base"]:getModule("Player"):GetUser(args)
    local targetchar = user:getCurrentCharacter()

    if target:getCash() >= price then
        target:removeMoney(price)
        exports.ghmattimysql:execute("UPDATE houses SET `cid` = @cid, `price` = @price, `model` = @model WHERE `id` = @id", {
            ['@cid'] = targetchar.id,
            ['@price'] = price,
            ['@id'] = hid,
            ['@model'] = model
        })
    else
        TriggerClientEvent('DoShortHudText', args, '你没有钱', 2)
    end
end)
