Trying to pull users who reacted to a specified message with a specified emoji, need some guidance

Here's my code, can't seem to get reactedUsers to populate with the right values. This makes it a map with 0 length. Is there anything obvious I'm missing here?

async execute(interaction) {
    await interaction.deferReply();
    var message = await interaction.channel.messages.fetch(
      interaction.options.getString("targetmessage")
    );

    var reactedUsers = await message.reactions.resolve(":poop:").users.cache;

    var winner = reactedUsers[Math.random(reactedUsers.count() - 1)];

    await interaction.editReply(
      `${winner.displayName} is the winner of the giveaway!`
    );
  },

async execute(interaction) {
    await interaction.deferReply();
    var message = await interaction.channel.messages.fetch(
      interaction.options.getString("targetmessage")
    );

    var reactedUsers = await message.reactions.resolve(":poop:").users.cache;

    var winner = reactedUsers[Math.random(reactedUsers.count() - 1)];

    await interaction.editReply(
      `${winner.displayName} is the winner of the giveaway!`
    );
  },

It is the Unicode character in the code, but discord translated it to :poop: when I pasted it into Discord for the help ticket for instance, this doesn't work either:

async execute(interaction) {
    var message = interaction.channel.messages.fetch(
      interaction.options.getString("targetMessage")
    );

    var reactedUsers = message.reactions.cache.filter((reaction) => {
      reaction.emoji.id === interaction.options.getString("entryEmoji");
    }).users.cache;

    var winner = reactedUsers[Math.random(reactedUsers.count() - 1)];

    await interaction.reply(`${winner.displayName} is the winner of the giveaway!`);
  },

async execute(interaction) {
    var message = interaction.channel.messages.fetch(
      interaction.options.getString("targetMessage")
    );

    var reactedUsers = message.reactions.cache.filter((reaction) => {
      reaction.emoji.id === interaction.options.getString("entryEmoji");
    }).users.cache;

    var winner = reactedUsers[Math.random(reactedUsers.count() - 1)];

    await interaction.reply(`${winner.displayName} is the winner of the giveaway!`);
  },

Fixed that issue, now running into a new one with reactedUsers being undefined

async execute(interaction) {
    let messageOption = await interaction.options.getString("targetmessage");
    let emojiOption = await interaction.options.getString("entryemoji");

    var message = await interaction.channel.messages.fetch(messageOption);

    var reactedUsers = await message.reactions.cache.filter((reaction) => {
      reaction.emoji.name == emojiOption;
    }).users;

    var winner = reactedUsers[Math.random(reactedUsers.count() - 1)];

    await interaction.reply(
      `${winner.displayName} is the winner of the giveaway!`
    );
  }

async execute(interaction) {
    let messageOption = await interaction.options.getString("targetmessage");
    let emojiOption = await interaction.options.getString("entryemoji");

    var message = await interaction.channel.messages.fetch(messageOption);

    var reactedUsers = await message.reactions.cache.filter((reaction) => {
      reaction.emoji.name == emojiOption;
    }).users;

    var winner = reactedUsers[Math.random(reactedUsers.count() - 1)];

    await interaction.reply(
      `${winner.displayName} is the winner of the giveaway!`
    );
  }

you aren't returning a value in the filter function

Madder•5w ago

it's always the dumbest mistakes huh Sorry, from what I can tell the filter function doesn’t require a return value, just as the native JS array.filter doesn’t require one (docs say they’re near identical but that collection.filter returns a collection rather than an array).

chewie 🌈•5w ago

They require a return value :thonk: a boolean to be precise, to know what passes the filter and what doesnt https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter#callbackfn

Okay, my bad Okay, that worked. Now reactedUsers is a Map with size 0, even though the message being pulled has 2 💩 reactions on it.

  async execute(interaction) {
    await interaction.deferReply({ ephemeral: true });
    let messageOption = await interaction.options.getString("targetmessage");
    let emojiOption = await interaction.options.getString("entryemoji");

    let message = await interaction.channel.messages.fetch(messageOption);

    let reactions = await message.reactions.cache.filter((reaction) => {
      return reaction.emoji.name == emojiOption ? true : false;
    });

    let reactedUsers = await reactions.get(emojiOption).users.cache;

    let winner = reactedUsers[Math.random(reactedUsers.count() - 1)];

    await interaction.editReply(
      `${winner.displayName} is the winner of the giveaway!`
    );
  }

  async execute(interaction) {
    await interaction.deferReply({ ephemeral: true });
    let messageOption = await interaction.options.getString("targetmessage");
    let emojiOption = await interaction.options.getString("entryemoji");

    let message = await interaction.channel.messages.fetch(messageOption);

    let reactions = await message.reactions.cache.filter((reaction) => {
      return reaction.emoji.name == emojiOption ? true : false;
    });

    let reactedUsers = await reactions.get(emojiOption).users.cache;

    let winner = reactedUsers[Math.random(reactedUsers.count() - 1)];

    await interaction.editReply(
      `${winner.displayName} is the winner of the giveaway!`
    );
  }

is this the problem?

d.js docs•5w ago

:method: GuildMemberManager#fetch @14.15.2 Fetches member(s) from a guild.

// Fetch all members from a guild
guild.members.fetch()
  .then(console.log)
  .catch(console.error);

// Fetch all members from a guild
guild.members.fetch()
  .then(console.log)
  .catch(console.error);

Unknown User•5w ago

Message Not Public

chewie 🌈•5w ago

no you should not do that you can just fetch the reaction and that should contain the users, hopefully

Madder•5w ago

How would I fetch the reaction?

chewie 🌈•5w ago

add a .fetch() to it

chewie 🌈•5w ago

I'm not 100% certain if that fetches the users though

Madder•5w ago

still a map with size 0 let reactedUsers = await reactions.get(emojiOption).fetch(); ahh okay let reactedUsers = await reactions.get(emojiOption).users.fetch(); empty map

Madder•5w ago

two reactions, one from myself and one from my friend the message id there is definitely correct sure one sec

Madder•5w ago

how would i do that? here's emojiOption

Madder•5w ago

i've just never seen that format before, apologies one sec okay this is working keys and emoji came out to 💩 now winner is undefined but that's not djs, just js, i can get that fixed thank you all!
