每次我嘗試使用我的機器人更改服務器中其他人的昵稱（甚至是朋友的服務器中的我自己），它都會失敗，給我帶來以下錯誤：(node:11620) UnhandledPromiseRejectionWarning: DiscordAPIError: Missing Permissions    at RequestHandler.execute (C:\Users\(User)\Desktop\Discord Bot\Nick-Cycle\node_modules\discord.js\src\rest\RequestHandler.js:170:25)    at processTicksAndRejections (internal/process/task_queues.js:97:5)(node:11620) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handledwith .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)(node:11620) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.我檢查了一下，它確實有管理昵稱，它的角色就在所有者下面。我試圖改變昵稱的人，他的最高角色遠遠低于機器人。機器人的角色、職位和管理昵稱權限的圖像。代碼如下：client.on('message', async message => {    const prefix = ";"    if (message.author.bot) return;    if (!message.guild) return;    if (!message.content.startsWith(prefix)) return;    const args = message.content.slice(prefix.length).trim().split(/ +/g);    const cmd = args.shift().toLowerCase();    switch(cmd) {        case "setnick":         if (!message.guild.me.hasPermission("MANAGE_NICKNAMES")) return message.channel.send("I don't have Manage Nicknames!");        if (!args[0]) return message.channel.send("Not enough arguments!");        if (args[0] === getUserFromMention(args[0])) {            const user = getUserFromMention(args[0])            if (!args[1]) return message.channel.send("Not enough arguments!");            message.guild.members.fetch(user).setNickname(args[1]);        }        else {            message.member.setNickname(args[0]);        }        break;    }    });怎么了？這是一個小故障嗎？角色中是否有問題？還是我的代碼有問題？
