No command handler found, still WIP

[MikeFairbrother-RLDatix]

I really don't understand what I am missing here and it's frustrating.
I've started a really simple bot. It loads, it responds to a simple hello message and a /ping command works perfectly.

I've added a new command called coinflip.

It resides in /commands/fun/ and is coinflip.js
It is registered and I can see it as a slash command to use.

Every time I run it, the response is "No command handler found, still WIP"

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

module.exports = {
    data: new SlashCommandBuilder()
        .setName('coinflip')
        .setDescription('Flip a coin to get Heads or Tails from the bot')
        .addStringOption(option =>
            option.setName('choice')
                .setDescription('Choose Heads or Tails (optional)')
                .addChoices(
                    { name: 'Heads', value: 'Heads' },
                    { name: 'Tails', value: 'Tails' }
                )),

async execute(interaction) {
    if (!(interaction instanceof ChatInputCommandInteraction)) return;

    const choice = interaction.options.getString('choice');
    const outcomes = ['Heads', 'Tails'];
    const result = outcomes[Math.floor(Math.random() * outcomes.length)];

    const response = choice ? `Your choice: **${choice}**\Flip Result: **${result}**` : `Flip Result: **${result}**`;

    if (interaction.deferred) {
        await interaction.editReply(response);
    } else {
        await interaction.reply(response);
    }
},
};

I know this will be something stupid, but I really don't understand what I am missing here. The ping.js is in command/utility and this new one is in command/fun. The commands are loaded dynamically etc, I've basically followed the guide to this point and now I try and add a custom command, it's falling over.

The issue is to do with your command handler or your interactionCreate event, you should join the Discord server and ask there and we'd be happy to help
