bot 的用户名未定义

Question

我收到这个错误UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'username' of undefined，这是由client.user.usernamein引起embed的.setFooter()。module.exports = {    name: 'suggest',    aliases: ['sug', 'suggestion'],    description: 'Suggest something for the Bot',    execute(message, client, args) {        const Discord = require('discord.js');        const filter = m => m.author.id === message.author.id;        message.channel.send(`Please provide a suggestion for the Bot or cancel this command with "cancel"!`)        message.channel.awaitMessages(filter, { max: 1, })            .then(async (collected) => {                if (collected.first().content.toLowerCase() === 'cancel') {                    message.reply("Your suggestion has been cancelled.")                }                else {                    let embed = new Discord.MessageEmbed()                        .setFooter(client.user.username, client.user.displayAvatarURL)                        .setTimestamp()                        .addField(`New Suggestion from:`, `**${message.author.tag}**`)                        .addField(`New Suggestion:`, `${collected.first().content}`)                        .setColor('0x0099ff');                    client.channels.fetch("702825446248808519").send(embed)                    message.channel.send(`Your suggestion has been filled to the staff team. Thank you!`)                }            })    },    catch(err) {        console.log(err)    }};

根据您在这里的评论

尝试 { command.execute(message, args); } 捕捉（错误）{ 控制台.错误（错误）；message.reply('尝试执行该命令时出错！'); } });

您没有client进入execute()，您需要这样做。

您还需要使用awaitonchannels.fetch()因为它返回一个承诺，所以替换client.channels.fetch("702825446248808519").send(embed)为：

const channel = await client.channels.fetch("702825446248808519")
channel.send(embed)
