我正在使用 discord.js 编写一个 discord 机器人，我正在处理一个建议命令

Question

I'm currently trying to get the bot to send a filler message to the channel I eventually want the suggestions to go to and have tried multiple methods to do so, but keep getting errors. I'm sure the solution is very simple, and any help is much appreciated.

suggest.js

module.exports = {
    name: 'suggest',
    aliases: ['suggestion'],
    description: 'Sends a suggestion to the <#700591796119535657> channel.',
    usage: '<your suggestion>',
    cooldown: 1,
    execute(message, args) {
        const Discord = require('discord.js');
        const client = new Discord.Client();
        const channel = client.channels.cache.get('701087240729657457');
        channel.send('test');
    },
};

error message in console upon running.suggest

This is a really easy fix. Just change the channel.send to message.channel.send and that should work. Tell me if you get any errors and I'll try to help:)
