Change your nickname command discord.js v14

Question

I'm trying to make a command that can change a user's nickname but I can't make it work. I have tried to find solutions but I can't.

Here is my code:

const { SlashCommandBuilder, EmbedBuilder } = require("discord.js");

module.exports = {
    data: new SlashCommandBuilder()
      .setName("nickname")
      .setDescription("Change your nickname")
      .addStringOption(option =>
        option.setName("nickname")
        .setDescription("New Nickname")
        .setRequired(true)
        ),

    async execute(interaction) {
      const { options } = interaction;
      const nick = options.getString("nickname");
      const member = interaction.author;
      
      const embed = new EmbedBuilder()
        .setDescription(`Succesfully changed your nickname to ${nick}`)
        .setColor(0xFFFFFE)
        .setTimestamp();

      await member.setNickname(`${nick}`)
        
      await interaction.reply({
        embeds: [embed],
        ephemeral: true
    
    });  
  }    
} 

I think the problem is with this but I'm not sure

await member.setNickname(`${nick}`)

Answer 1

It's because interaction.author is undefined . You probably thought that it's like message.author but that's still a User , not a GuildMember and only members have the setNickname() method.

You should get the member instead of the user though. Try something like this:

const member = await interaction.guild.members.fetch(interaction.user.id)

You could also use options.getMember("nickname") if you used addUserOption() instead of addStringOption() .

Answer 2

I was just making a similar command and ran into the same issue as you. I realized the member that I'm trying to change the nickname of, had another role assigned to them, which was higher than the role of the bot. Give this a look and let me know. Also, make sure you have GatewayIntentBits.Guilds and GatewayIntentBits.GuildMembers passed in your intents.
