How do I deal with invalid number and .catch()

Question

I am trying to fix this code but I failed This is a code to send a message to members When I choose any number, it sends an invalid number, and this error appears to me.

I tried to fix it but failed if there is any help I would be grateful. The code was working fine about a month ago, but it has stopped now. I think it has something to do with updating the Discord.js

client.on('message ', async (message) => {
  if (!message.guild || message.author.bot) return;
  if (!message.content.startsWith(prefix)) return;
  if (message.content.startsWith(`${prefix}bc`)) {
    if (!message.member.hasPermission('ADMINISTRATOR'))
      return message.reply('You dont have Permissions.');
    if (message.guild.interval)
      return message.reply(
        '**Another broadcast is running, please wait for it to finish ** '
      );
    const args = message.content.split(' ').slice(1).join(' ');
    if (!args)
      return message.reply(
        '**Please send a message after the command to send it**'
      );

    message.channel
      .send(
        '>>> **[1] All members\n[2] Connected Members\n[3]Special ranks\n[0] Cancel**'
      )
      .then((m) => {
        message.channel
          .awaitMessages((msg) => msg.author.id === message.author.id, {
            max: 1,
            time: 1000 * 60 * 2,
            errors: ['time'],
          })
          .then(async (c) => {
            var members = null;
            if (c.first().content === '1') {
              members = message.guild.members.array();
              c.first().delete();
              m.delete();
            }
            if (c.first().content === '2') {
              members = message.guild.members
                .filter((m) => m.presence.status !== 'offline')
                .array();

              c.first().delete();
              m.delete();
            }
            if (c.first().content == '0') {

              m.delete();
              message.channel.send(
                '**The order has been canceled successfully**'
              );
            }
            if (c.first().content === '3') {
              m.edit('**>>> Please enter the rank name**').then((ms) => {

                        .send('**:x:I cannot find the rank for the message**')

Answer 1

If you working with Discord.Js 12, you have to use cache. So message.guild.roles.cache.find()

Documentation

Answer 2

discord.js v12 and higher use Managers , so you'll have to pass through the cache property.

// change
const role = message.guild.roles.find(
  (role) => role.name === c.first().content
);

// to
const role = message.guild.roles.cache.find(
  (role) => role.name === c.first().content
);


// and change
members = message.guild.roles.get(roleID).members.array();

// to
members = message.guild.roles.cache.get(roleID).members.array();
