Cannot read property 'emoji' of undefined - node.js

Question

I'm trying to make it so I can verify someones question but the usual reaction.emoji.name check doesn't work. It says that it's undefined. But I've used it so many times without defining it. I'm very lost help would be appreciated.
const {Client, Collection, GuildMember, User, MessageEmbed, Message} = require("discord.js");
module.exports.run = async(client, message, args, member, reaction) => {
var woord = '!poll'
var question = args.slice(0).join(' ')
var pollChannel = message.guild.channels.cache.find(c => c.id === `875406886986477569`)
var poll = new MessageEmbed()
.setTitle(`${message.author.username} wil een poll maken.`)
.setDescription(question)
.setColor('#eb8dd8')
.setFooter(`Poll gemaakt door: `+ message.author.username)
var success = new MessageEmbed()
.setDescription(question)
.setColor('#eb8dd8')
.setFooter("Poll started door: "+ message.author.username)
if(message.content.includes(woord)) {
message.delete({timeout:0})
}
if(message.member.roles.cache.some(r => r.name === 'Barman')) {
if(message.channel.name.includes("🙇-poll")) {
if(args[1]) {
message.delete()
message.guild.channels.create(message.author.username, { permissionOverwrites:[
{
deny: 'VIEW_CHANNEL',
id: message.guild.id
},
{
allow: 'VIEW_CHANNEL',
id: message.author.id
},
],
}).then(channel => {
channel.send(poll).then(poll => {
poll.react('✅')
.then(() => poll.react('❌'));
})
})
} else {
message.delete()
}
}
}
if(reaction.emoji.name === '✅') {
console.log('check!')
}
}
module.exports.help = {
name: "test"
}
