So, i have been trying to make a ban command. I basically used the same system on a kick command, but here it didnt work and just gave me an error. I am confused since in the error it doesnt display a line of code or something.

My Command / Code:

module.exports = {

    name: 'ban',

    description: "Ban Command.",

    execute(msg, args){

    const Discord = require('discord.js')

    const Embeds = require('./../embed')

    let perms = msg.member.permissions  

    let has_kick = perms.has("BAN_MEMBERS")

    if (has_kick === true) {

        const toban = msg.mentions.members.first()

        delete args[0]

        var string = args.join(' ')

        Embeds.error(toban, `You have been banned from ${msg.guild.name} by the user ${msg.author} with the reason ${string}`)

        setTimeout(function(){ 

            try {

            toban.ban(`was banned by ${msg.author} for: ${string}`)

            Embeds.kicked(msg.channel, `${toban} has been banned by ${msg.author} from the server with the following reason: ${string}`, `Banned User from the server`)

            } catch {

                Embeds.error(msg.channel, `I dont have permissions to ban ${toban} `, "Error")

            }

         }, 1000); 

    } else {

        const toban = msg.mentions.members.first()

        Embeds.error(msg.channel, `You dont have permissions to Ban ${toban} `, "Error")

    }

}

}

The Error:
