I'm trying to write a discord bot, right now it's a command to get married.

Everything works as it should, except for one thing. In the awaitReactions function, I have a time of 10 seconds, and after this time I get this error:

node:internal/process/promises:246 triggerUncaughtException(err, true /* fromPromise */); [UnhandledPromiseRejection: This error originated either by throwing inside of a n async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "#".] { code: 'ERR_UNHANDLED_REJECTION' }

I can't understand why this is happening, I have .catch() at the end of the function and in theory everything should work as it should.

Why doesn't .catch() work in my case? What could be the problem?

const { Command } = require('discord.js-commando');
const db = require("quick.db");


module.exports = class MarryCommand extends Command {
  constructor(client) {
    super(client, {
      name: 'marry',
      memberName: 'marry',
      group: 'test',
      description: 'Marry the mentioned user',
      guildOnly: true,
      args: [
        {
          key: 'userToMarry',
          prompt: 'Please select the member you wish to marry.',
          type: 'member'
        }
      ]
    });
  }

  run(message, { userToMarry }) {
    const exists = db.get(`${message.author.id}.user`);
    const married = db.get(`${userToMarry.id}.user`);
    if (!userToMarry) {
      return message.channel.send('Please try again with a valid user.')}
    if (exists == message.author.id) {
      return message.channel.send('You are already married!')}
    if (married == userToMarry.id) {
      return message.channel.send('This user is already married!')}
    if (userToMarry.id == message.author.id) {
      return message.channel.send('You cannot marry yourself!');
    }
    if (exists != message.author.id && married != userToMarry.id) {
    message.channel.send(`**Important announcement!**
    
    ${message.author} makes a marriage proposal ${userToMarry}
    
    Are you ready to get married?`).then(message => {
      message.react('
