When trying to use the following code i get the error messages Property 'forEach' does not exist on type 'Collection<string, GuildMember> and Property 'size' does not exist on type 'Collection<string, GuildMember>

import { Message } from "discord.js";

export default {
    callback: async (message: Message, ...args: string[]) => {
        const channel2pullFrom = message.guild.channels.cache.get('964675235314020442')
        const sendersChannel = message.member.voice.channel.id
        const totalCount = channel2pullFrom.members.size
    
        if (!message.member.permissions.has('MOVE_MEMBERS')) return
        if (!message.member.voice.channel) return message.reply("Error: Executor of command is not in a Voice Channel.")
       
        channel2pullFrom.members.forEach((member) => {
            member.voice.setChannel(sendersChannel)
        })
       
        message.reply(`Moved ${totalCount} members.`)
    }
}

I have no idea why that's happening and couldn't find anything abour this error when working with DiscordJS.

Here's the full error log:

    return new TSError(diagnosticText, diagnosticCodes);
           ^

When console logging 'message.member.voice' this get's logged:

CodePudding user response：

This will check that the channel being pulled from is a voice channel and return if it isn’t. If you run this and nothing happens and nothing errors then the channel if you set for channel2pullFrom is not a VC

The issue was that the correct intents were not specified. Change intents to intents: 32767,

import { Message } from "discord.js";

    callback: async (message: Message, ...args: string[]) => {
        const channel2pullFrom = message.guild.channels.cache.get('964675235314020442')
    // you could also dynamically set this by making it one of the args
    // const channel2pullFrom = message.guild.channels.cache.get(args[0])
    // above line won’t work without knowing more on how your args are handled (are they shifted, etc)
        if (channel2pullFrom.type != 'GUILD_VOICE') {
            return
        } else {
            const sendersChannel = message.member.voice.channelId
            const totalCount = channel2pullFrom.members.size
