Discord.js v13 why is my tempmute command not working?

I’ve made a tempmute command for my discord bot and it almost works. It has quite a few foolproofing measures like preventing the bot from muting themselves, not working if the time isn’t specified and such. I am using the npm ms package to deal with the mute duration (https://www.npmjs.com/package/ms). when instead of specifying an amount of time I type in gibberish it works as intended and replies with the correct message. The problem is that when I type in a 100% correct command it responds asthough I didn’t specify the time correctly instead of muting the user for that amount of time. here’s how it looks. Any ideas as to why that is?
My code is here:

const ms = require('ms');
const { Permissions, MessageActionRow, UserFlags } = require('discord.js');

module.exports = {
    name: 'tempmute',
    description: "Temporarily mutes a user",
    execute(message, args)
    {
        const target = message.mentions.members.first();
        let muteRole = message.guild.roles.cache.find(role => role.name === "muted");
        if(message.member.permissions.has(Permissions.FLAGS.MODERATE_MEMBERS))
        {
            if(target)
            {
                let memberTarget = message.guild.members.cache.get(target.id);
                if(target.id == 'myBotsID')
                {
                    message.reply("I can't mute myself.")
                }
                else if(message.member == target)
                {
                    message.reply("You can't mute yourself!")
                }
                else if(memberTarget.permissions.has(Permissions.FLAGS.MODERATE_MEMBERS))
                {
                    message.channel.send(`<@${memberTarget.user.id}> has been muted for ${ms(ms(args[1]))}`);                
                }
                else 
                {
                    if(!args[1]) 
                    {
                        return message.reply("Time not specified.")
                    }
                    else
                    {
                        let time = ms(args[1])
                        memberTarget.roles.add(muteRole.id); 
                        try {
                            message.reply("<@" + memberTarget.user.id + ">" + "has been muted for " + ms(ms(args[1])).catch(console.error))
                            setTimeout(function () {
                                memberTarget.roles.remove(muteRole.id);
                            }, time);
                        } catch (err) {
                            message.reply("Can't transform that into milliseconds `"+args[1]+"`")
                            return
                        }
                    }
                }
            }
            else
            {
                message.reply("You have to mention a valid member of this server.")
            }
        }
        else
        {
            message.reply("You can't use that.")
        }
    }
