other arguments than `client` is not being passed to event handler

I am scaffolding code for my bot based of this guide: https://discordjs.guide/creating-your-bot/event-handling.html#reading-event-files But when any events other than ready (which requires 2 or more arguments passed) are invoked, it crashes with the following error:

2 | 
3 | module.exports = {
4 |     name: Events.InteractionCreate,
5 |     once: false,
6 |     async execute(client, interaction) {
7 |         if(!interaction.isChatInputCommand()) return
                ^
TypeError: undefined is not an object (evaluating 'interaction.isChatInputCommand')

2 | 
3 | module.exports = {
4 |     name: Events.InteractionCreate,
5 |     once: false,
6 |     async execute(client, interaction) {
7 |         if(!interaction.isChatInputCommand()) return
                ^
TypeError: undefined is not an object (evaluating 'interaction.isChatInputCommand')

I suspect that when interactionCreate is called (when I invoke a slash command, for example), interaction is not passed to the event file. Sample code index.ts (the part where I register events)

const eventsPath = path.join(__dirname, 'events')
const eventFiles = fs.readdirSync(eventsPath).filter(file => file.endsWith('.js'))
for (const file of eventFiles) {
    const filePath = path.join(eventsPath, file)
    const event = require(filePath)
    if (event.once) {
        client.once(event.name, (...args) => event.execute(...args))
    } else {
        client.on(event.name, (...args) => event.execute(...args))
    }
}

const eventsPath = path.join(__dirname, 'events')
const eventFiles = fs.readdirSync(eventsPath).filter(file => file.endsWith('.js'))
for (const file of eventFiles) {
    const filePath = path.join(eventsPath, file)
    const event = require(filePath)
    if (event.once) {
        client.once(event.name, (...args) => event.execute(...args))
    } else {
        client.on(event.name, (...args) => event.execute(...args))
    }
}

events/interactionCreate.js

const { Events } = require('discord.js')

module.exports = {
    name: Events.InteractionCreate,
    once: false,
    async execute(client, interaction) {
                if(!interaction.isChatInputCommand()) return
                // Handling commands ...
    },
}

const { Events } = require('discord.js')

module.exports = {
    name: Events.InteractionCreate,
    once: false,
    async execute(client, interaction) {
                if(!interaction.isChatInputCommand()) return
                // Handling commands ...
    },
}

Yes I know it's not a good idea mixing ES5 and ESM, but I don't know does discord.js support it fully (I just returned from a year hiatus), the guide website still have references using ES5... Any help would be appreciated.

No event, except for the ready event emits with a client you either should remove the client parameter, as virtually all djs structures have a client property, or pass it in in your event handler

alright, I will try removing the client parameter.. @wolvinny 🌈 it works! thank you so much.. by the way, is my current code structure (main file is typescript-based, events and commands are still ES5-based) okay, should I change it or keep it that way?

treble/luna•3mo ago

djs is fully compatible with typescript so it should work
