Bot to Assign Reacting User to a Role in Discord

Question

I am trying to make a Discord Bot that reads every Emoji Reaction in a Server and assigns the reacting User with a particular role that is specific to the Emoji.

My code should Assign the Role Red to Users reacting with ???? in any message in the server. Assign the Role Blue to Users reacting with ???? in any message in the server. Assign the Role Yellow to Users reacting with ???? in any message in the server.

Here are the IDs of these roles:

Red: <@&870162738561814578>
Blue: <@&870162842983206922>
Yellow: <@&870162885412810773>

Here's a code snippet of the bot:

const RYellow = '<@&870162885412810773>';
const RBlue = '<@&870162842983206922>';
const RRed = '<@&870162738561814578>';

const RRedEmoji = '????';
const RBlueEmoji = '????';
const RYellowEmoji = '????';

client.on('messageReactionAdd', async (reaction, user) => {
  if (reaction) await reaction.fetch();
  if (user.bot) return;
  console.log(reaction);
  if (reaction.emoji.name === RYellowEmoji) {
    await reaction.message.guild.members.cache.get(user.id).roles.add(RYellow);
    await reaction.message.guild.members.cache.get(user.id).roles.remove(RRed);
    await reaction.message.guild.members.cache.get(user.id).roles.remove(RBlue);
  }
  if (reaction.emoji.name === RRedEmoji) {
    await reaction.message.guild.members.cache.get(user.id).roles.add(RRed);
    await reaction.message.guild.members.cache
      .get(user.id)
      .roles.remove(RYellow);
    await reaction.message.guild.members.cache.get(user.id).roles.remove(RBlue);
  }
  if (reaction.emoji.name === RBlueEmoji) {
    await reaction.message.guild.members.cache.get(user.id).roles.add(RBlue);
    await reaction.message.guild.members.cache.get(user.id).roles.remove(RRed);
    await reaction.message.guild.members.cache
      .get(user.id)
      .roles.remove(RYellow);
  }
});

And heres the error:

E:\Projects\DBot\node_modules\discord.js\src\managers\GuildMemberRoleManager.js:93 throw new TypeError('INVALID_TYPE', 'roles', 'Role, Snowflake or Array or Collection of Roles or Snowflakes'); ^

TypeError [INVALID_TYPE]: Supplied roles is not a Role, Snowflake or Array or Collection of Roles or Snowflakes. at GuildMemberRoleManager.add (E:\Projects\DBot\node_modules\discord.js\src\managers\GuildMemberRoleManager.js:93:15) at Client. (E:\Projects\DBot\index.js:49:71) at processTicksAndRejections (node:internal/process/task_queues:96:5) { [Symbol(code)]: 'INVALID_TYPE' }

So, what am I doing wrong?

<@&870162885412810773> is not a snowflake or an ID. You'll need to remove <@& and >:

const RYellow = '870162885412810773'
const RBlue = '870162842983206922'
const RRed = '870162738561814578'
