It won't let me add a roles to a user please help!

Answer 1

You are calling user.roles.add() in the middle of the hash definition of module_exports.
Read through your code again. It's a syntax error.

Answer 2

The issue stems from this, roles is an element of a member which is the parent of a user. user does not contain the element of roles. The code was trying to add roles to a user rather than a member.
This will help you out.
const { SlashCommandBuilder } = require("#discordjs/builders");
const { Permissions } = require("discord.js");
module.exports = {
data: new SlashCommandBuilder()
.setName("mute")
.setDescription("Mute a user on the server")
.addUserOption((option) =>
option
.setName("user")
.setDescription("The user you want to mute")
.setRequired(true)
),
execute: async (interaction) => {
const user = interaction.options.getUser("user");
if (!interaction.member.permissions.has(Permissions.FLAGS.MANAGE_ROLES)) {
return interaction.editReply({
content: `:x: | Manage Roles Permission is required to perform that action!`,
ephemeral: true,
});
}
//adding the below line
const member2mute = interaction.guild.members.cache.get(user.id)
//changing the below line
member2mute.roles.add("958443243836702859");
return interaction.editReply("Muted!")
},
};
