Reaction Collector not getting the correct size (capped at 1)

discord.js: 14.15.3 nodejs: v18.16.0 My intents are: Guilds GuildMessages GuildMessageReactions I'm using a reaction collector. Any time I print the collected.size, it returns 1 despite the filter showing multiple users reacting.

const filter = (reaction, user) => {
    const userMember = guild.members.cache.get(user.id)
    console.log(reaction.emoji.name === '🔑' && userMember.roles.cache.has(modRoleId))
    return reaction.emoji.name === '🔑' && userMember.roles.cache.has(modRoleId)
}

const expireTimeMS = 20000

botMsg.awaitReactions({ filter, time: expireTimeMS })
    .then(collected => {
    console.log(collected.size)
    if (member.roles.cache.has(administratorRoleId)) {
        //console.log('User is already an administrator!')
        return
    }
    if (collected.size >= modsRequired) {
        member.roles.add(administratorRoleId)
        channel.send(`confirmation here`)
    }
});

const filter = (reaction, user) => {
    const userMember = guild.members.cache.get(user.id)
    console.log(reaction.emoji.name === '🔑' && userMember.roles.cache.has(modRoleId))
    return reaction.emoji.name === '🔑' && userMember.roles.cache.has(modRoleId)
}

const expireTimeMS = 20000

botMsg.awaitReactions({ filter, time: expireTimeMS })
    .then(collected => {
    console.log(collected.size)
    if (member.roles.cache.has(administratorRoleId)) {
        //console.log('User is already an administrator!')
        return
    }
    if (collected.size >= modsRequired) {
        member.roles.add(administratorRoleId)
        channel.send(`confirmation here`)
    }
});

console output when 2 users react:

true
true
1

true
true
1

it prints true twice in the filter, but the collected.size is only 1. What am I doing wrong? If no users react, it does print zero. please @ me if someone responds, server is on @s only

while the event emits per user, MessageReaction is per emoji so since you seem to only be collecting for a single emoji, it's always going to only have one MessageReaction you'd be looking for <MessageReaction>.users.cache.size

I see. I'm not at my computer right now, what would be the generally standard way to get the specific messagereaction I want from the collector? Would I just want to find 🔑 in collected?

duck•5mo ago

well since there's only one item in the collection, you can just use <Collection>.first()

ArdiOP•5mo ago

Was going to ask about other reactions but yeah my filter does force only one reaction. What if the collection is empty?

duck•5mo ago

well if there were multiple in the collection, yes it's keyed by unicode character (or id in the case of custom emojis), so you can get 🔑 if the collection is empty first will return undefined

alright I can just add a check for if its empty Alright, so I'm able to collect multiple users. However, the filter isn't applied to <MessageReaction>.users so if people who got filtered out reacted it still shows up in the users I got.

duck•5mo ago

I suppose you could just filter the users after the fact and only use the collector's filter for the emoji

That's what I was thinking. This was the solution, thanks.
