How to make a bot that deletes a message and posts it in another channel based on reactions

Question

I'm trying to make it so when my bot picks up a reaction in a specific channel, it'll see if it hit 10 reactions on a specific reaction. Then it'll delete the reacted message and post it into another specific channel with a message attached to it.

Here's the code

doopliss.on('message', message => {
  if (message.channel.id === "587066921422290953") {
    setTimeout(function(){
      message.react(message.guild.emojis.get('587070377696690177'))
    }, 10)
    setTimeout(function(){
      message.react(message.guild.emojis.get('587071853609353256'))
    }, 50)
    setTimeout(function(){
      message.react(message.guild.emojis.get('587070377704816640'))
    }, 100)
  }
});
const message = require("discord.js");
const emoji = require("discord.js");
const reaction = require("discord.js");
doopliss.on('message', message => {
  if (message.channel.id === "587066921422290953") {
  let limit = 2; // number of thumbsdown reactions you need
  if (message.reaction.emoji.name == message.guild.emojis.get('587070377696690177') 
  && reaction.count >= limit) message.reaction.message.delete();
  let tcontent = message.reaction.message.content
  let accept = message.guild.channels.get('587097086256873483')

  accept.send(`${tcontent} \`\`\`This server suggestion has been accepted by the community! Great job! Now a staff member just needs to forward it to username.\`\`\``)
}})

Can't figure out how to do this.

Expected Result: Bot sees if post has 10 reactions, then delete it and take the same message to a different channel Actual Result: An error occurs Cannot read 'channel' property

First I want to say that some question here like this one have what you search.

Moreover, the discord documentation and the guide provide an awaiting reactions section.

There is some other question that refer to the subject or the function used in the guide and by searching a bit you can even find question like this one which is almost the same thing as you.

However, here is a complete example of what you want to do. You can add a timer to the promise instead of just waiting. I didn't use the reaction collector because promise are a bit faster, but you can also create a management system of multiple collector , or use the client.on('messageReactionAdd').

const Discord = require('discord.js');
const config = require('./config.json');


const channelSuggestion = '<channelID>';
const channelSend = '<channelID>';
const emojiReact = '<emojiID>';
const prefixSuggestion = '!';
const reactionMax = 11;

const client = new Discord.Client();
client.on('ready', () => {
  console.log('Starting!');
  client.user.setActivity(config.activity);
});

client.on('message', (msg) => {
  if ((msg.content[0] === prefixSuggestion) && (msg.channel.type === 'dm')){
    sendSuggestion(msg);
  }
});


function filter(reaction) {
  return reaction.emoji.id === emojiReact;
}

function moveSuggestion(msg) {
  client.channels.get(channelSend).send(msg.content)
    .then(() => msg.delete()).catch(err => console.log(error));
}

function sendSuggestion(msg){
  client.channels.get(channelSuggestion).send(msg.content.substr(1))
    .then((newMsg) => newMsg.react(emojiReact))
    .then((newMsgReaction) => 
      newMsgReaction.message
      .awaitReactions(filter, {max: reactionMax})//, time: 15000, errors: ['time']})
      .then(collected => {
        moveSuggestion(newMsgReaction.message);
      })
      // .catch(collected => {
      //   console.log(`After a minute, only ${collected.size} out of 10 reacted.`);
      // })
     );
}

client.login(config.token)
  .then(() => console.log("We're in!"))
  .catch((err) => console.log(err));

The bot will listen to dm message (I don't know how you want your bot to send the suggestion message, so I made my own way) which start with a !.
Then the bot will send a message to a specific channel, wait for N person to add a reaction, and then will send the message to another channel.
