I've tried my best to comment what I believe my code is doing (or rather what it's supposed to be doing).

Code in separate message, please hold...

# 
const { SlashCommandBuilder } = require('@discordjs/builders')

module.exports = {
    data: new SlashCommandBuilder()
        .setName('vote')
        .setDescription('(For Chip Only!) Make a poll!')
        .addStringOption(option =>
            option.setName('question')
                .setDescription('The question to be asked')
                .setRequired(true)),
    async execute(interaction, client, MessageEmbed, minutes) {
        // Grab the question from the interaction options
        const question = interaction.options.getString('question')
        // Define poll embed
        let poll = new MessageEmbed()
            .setTitle(`Poll: ${question}`)
            .setDescription('React with the appropriate emoji to vote!')
            .setFooter({ text: 'Wee6, a bot by ChunkleChip', iconURL: `https://cdn.discordapp.com/avatars/${client.user.id}/${client.user.avatar}.png?size=4096` })
        // Define the reply to the interaction, which is the poll question itself
        poll = await interaction.reply({ embeds: [poll], fetchReply: true })
        // Add reactions and consequently send reply at the same time
        poll.react('👍').then(() => poll.react('👎')).then(() => poll.react('🤷‍♂️'))
        // Define a filter for the reactions once they've been collected
        const filter = (reaction, user) => {
            return (['👍', '👎', '🤷‍♂️'].includes(reaction.emoji.name) && user.id === message.author.id)
        }
        // Wait 10 seconds for reactions to be collected, then map the reactions for parsing as a edit to the original embed
        poll.awaitReactions({ filter, max: 65535, time: 10000, errors: ['time'] })
            .then(collected => {
                const results = collected.map(reaction => reaction.count)
# 
                const totalVotes = results.reduce((a, b) => a + b, 0)
                const resultsString = results.map(result => `${result} ${result.emoji.name}`).join(', ')
                interaction.editReply({ content: `Results: ${resultsString}. Total: ${totalVotes}`, ephemeral: false })
            })
    },
}

I will admit, I don't fully understand promises, but I am trying my best.

#

so what is the full error of the code ?

modern yarrow
#

Oh, I guess I should ask a question. What am I doing wrong here? This is the full error.

the error is not really clear which cause it tho sad

modern yarrow
#

That's my point exactly. It throws this error after the embed gets sent then has reactions put on it.

#

After the 10 second timeout

jagged sparrow
#

you can try to try catch it to see errors

# 
try {
// block of code
} catch (error) {
console.error(error)
}

Alright, lemme take a crack at it.

Update for how I fixed it 🙂
