I've already added the procfile with Worker node index.js.

Someone said I have a problem with the mute.js file and here it is:

const ms = require("ms");
module.exports = {
    name: "mute",
    description: "This mutes a member",
    execute(message, args) {
        let role = message.guild.roles.cache.find((r) => r.name === "Mod");

        if (message.member.permissions.has("MUTE_MEMBERS")) {
            message.channel.send("you have the permission to mute members");
        } else {
            message.channel.send("you dont have the permission to mute members");
        }

        const target = message.mentions.users.first();
        if (target) {
            let mainRole = message.guild.roles.cache.find((role) => role.name === "member");
            let muteRole = message.guild.roles.cache.find((role) => role.name === "Muted");

            let memberTarget = message.guild.members.cache.get(target.id);

            if (!args[1]) {
                memberTarget.roles.remove(mainRole.id);
                memberTarget.roles.add(muteRole.id);
                message.channel.send(`<@${memberTarget.user.id}> has been muted`);
                return;
            }
            memberTarget.roles.remove(mainRole.id);
            memberTarget.roles.add(muteRole.id);
            message.channel.send(`<@${memberTarget.user.id}> has been muted for ${ms(ms(args[1]))}`);

            setTimeout(function () {
                memberTarget.roles.remove(muteRole.id);
                memberTarget.roles.add(mainRole.id);
            }, ms(args[1]));
        } else {
            message.channel.send("Cant find that member!");
        }
    },
};

I've never had any problems with my other bots when deploying them to Heroku. Any help is appreciated!!
