未定义用户名，试图发出建议命令，可能是客户端或用户错误

Question

UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'username' of undefined

所以我修复了一些其他错误，现在我在这里，但idk该怎么办。可能与用户的严格性有关？还是客户？请帮助我。

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)
    }
};

根据您的评论here

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

您没有将client传递到execute()，需要这样做
