我有一個單獨的 JSON 文件，鏈接為const Players = require('./Database/Players.json');和一個遍歷代碼的 praserclient.on('message', message => {    if (message.content.toLowerCase() ==='smack activate') {                let PlayerData = [message.author.username];        Activate [message.author.username] = {        AccountActive: 1,        Health: 100,        Level: 1,        Lust: 0,        Items: ""        };        var parsedata = JSON.parse(Players)   // <-----------        if (parsedata.PlayerData.accountactive === 1) {            message.channel.send ("Account Already Activated");            return;        }        fs.writeFile("./Database/Players.json", JSON.stringify (Activate, null, 4), err => {            if (err) throw err;            message.channel.send ("Account Activated")        });    };但似乎沒有任何效果..我做錯了什么？我收到此錯誤消息undefined:1[object Object] ^
