Cannot read properties of undefined (reading 'channel')

I'm trying to make a /ping command for my discord. The bot is using type script and a plugin called WOKCommands.

I'm getting this error below (This only happens when i use the slash command instead of the prefix command {>ping} ).

Cannot read properties of undefined (reading 'channel')

this happens because of line const msg = await message.channel.send ({content: `> 🏓 Pinging..`}) in the code below

import { Client, Message, MessageEmbed, MessageActionRow, MessageButton, MessageSelectMenu } from'discord.js';
const db = require('quick.db')
const moment = require('moment')
import { ICommand } from "wokcommands";


export default {
    name: 'ping',
    description: "Fetches the client latency",
    category: "Utilities",

    slash: 'both',
    testonly: true,


    /** 
     * @param {Client} client 
     * @param {Message} message 
     * @param {String[]} args 
     */

    callback: async({client, message, args}) => {
        const msg = await message.channel.send ({content: `> 🏓 Pinging..`})
        msg.edit({content: `> 🏓 Pong! Latency: **${client.ws.ping}ms**`})
    }
} as ICommand

This is the cause of your error. When you use a slash command, there is no message involved. Slash commands are not sent as messages, they are sent as interactions. When you use your ping command as a slash command, message is undefined.

Additionally, when using slash commands you must send a reply instead of simply sending a message in the channel. Otherwise, you will get an additional error. I would recommend switching to using the .reply() method for both prefix commands and slash commands here (though I haven't made said switch for your prefix commands in the below code). This is one way to fix your callback:

({ client, message, interaction, args }) => {
    if (message) {
        const msg = await message.channel.send ({content: `> 🏓 Pinging..`})
        msg.edit({content: `> 🏓 Pong! Latency: **${client.ws.ping}ms**`})
    }
    else if (interaction) {
        await interaction.reply({content: `> 🏓 Pinging..`});
        interaction.editReply({content: `> 🏓 Pong! Latency: **${client.ws.ping}ms**`});
    }
}

You may find the WOKCommands documentation useful for issues such as this one. Their docs even have an example of a ping command, albeit a simpler version.
