Node.js Discord Bot: Typeerror: Cannot read property of 'send' undefined

Question

EDIT: big shout out to the guys who are helping with feedback, still very new to the scene, but just so fascinated by it so i keep trying. i have enabled a new command handler and it seemed to have just jacked up everything i have. its kind of a general problem throughout my code but if i can get help with this command i will be able to fix it all.

i am currently having a problem with my delete command. it works, but it throws errors and im missing something obvious. any help is greatly appreciated. i seem to have a problem with not defining what i want it to do, it used to work flawlessly when i had a basic command haandler, but i have since moved on to a cleaner one and i know i'm just missing something obvious. damn near wrecked the entire code trying to figure it out

The error is:

TypeError: Cannot read property 'send' of undefined

main.js

const Discord = require('discord.js');
require('dotenv').config();
const client = new Discord.Client({ partials: ["MESSAGE", "CHANNEL", "REACTION"] });
const fs = require('fs');


client.commands = new Discord.Collection();
client.events = new Discord.Collection();

['command_handler', 'event_handler'].forEach(handler =>{
    require(`./handlers/${handler}`)(client, Discord)
})

client.login(process.env.DISCORD_TOKEN);

COMMAND HANDLER

const fs = require('fs');

module.exports = (client, Discord) =>{
    const command_files = fs.readdirSync('./commands/').filter(file => file.endsWith('js'))

    for(const file of command_files){
        const command = require(`../commands/${file}`);
        if(command.name){
            client.commands.set(command.name, command);
        } else {
            continue;
        }
    }
}

I THINK THIS IS MY EXECUTE COMMAND. also known as my message.js

require('dotenv').config();
module.exports = (Discord, client, message) => {
    const prefix = process.env.PREFIX;
    const send = require ('discord.js');

    if(!message.content.startsWith(prefix) || message.author.bot) return;

    const args = message.content.slice(prefix.length).split(/ +/);
    const cmd = args.shift().toLowerCase();

    const command = client.commands.get(cmd) || 
        client.commands.find(a => a.aliases && a.aliases.includes(cmd));

    if(command) command.execute(client, message, args, Discord);  

    try {
        command.execute(message, args, cmd, client, Discord);
    } catch (err) {
        message.reply("whoops, shit got fuckity on my backend");
        console.log(err);
    }
}

DELETE COMMAND


const message = require("../events/guild/message");
module.exports = {
    name: 'delete',
    description: "delete messages",
        execute(client, message, args, Discord) {
            try {
            if (!args[0]) return message.channel.send("type a number with the command doofus");
            if (isNaN(args[0])) return message.channel.send("bruh enter a real number");

            if (args[0] > 100) return message.channel.send("way too much");
            if (args[0] < 1) return message.channel.send("stop tryna be a funny guy")

            return message.channel.messages.fetch({ limit: args[0] }).then(messages => {
                message.channel.bulkDelete(messages);


                message.channel.send("you saw nothing");
            })
     } catch (err) {
            console.log(err);
     }
    }
}

What is the error returned? What's the code that throws the error? — Don Diego
Your async execute(client, message, args, Discord) should be non-async, with return message.channel.messages.fetch(...) instead of await message.channel.messages.fetch(...). — Tomalak
The error says "Cannot read property 'send' of undefined" on line 6 in your "delete" command. So obviously message.channel is undefined, which would mean that message probably is not what you think it is. — Tomalak
...and the UnhandledPromiseRejectionWarning comes from the missing try/catch in your delete command. In order to at least keep the bot from crashing, wrap the function body in a try/catch block and dump any errors to console. — Tomalak

You're execute functions is execute(client, message, args, Discord). So, the first parameter should always be client.

However, in your "message.js" file, you wrote:

try {
        command.execute(message, args, cmd, client, Discord);
} catch (err) {
        **some code here**
}

Here, you're passing in message first, so your order of the parameters is messed up. Fix that by rearranging the parameters and the code should work.
