Discord js role.members not return all members

I have created a bot that allows, among other things, to send a message to those who belong to a certain role. The bot is hosted on Heroku (free version, with a mandatory restart every day) When I try to retrieve the members of the role in question I have the impression to retrieve only the members who are connected since the bot restart (or who have been online). I have 27 members of a role but the bot retrieves only 3

Here is my code :

client.on("messageCreate", message =>{
  message.guild.roles.fetch(roleMembersId).then(role => {
   role.members.forEach(member => { 
      console.log("user "+ member.user.username)
      })
   })
})

I have the same behavior if I use interactions or directly the client

Is there a solution to this problem? I did not find anything like this when I searched

Perhaps you're missing the GUILD_PRESENCES intent.

For discord.js v14:

const { Client, GatewayIntentBits, Partials } = require('discord.js');

const client = new Client({
  intents: [
    GatewayIntentBits.Guilds, GatewayIntentBits.GuildMessages, GatewayIntentBits.GuildPresences
  ]
})

For lower versions you can try and use:

const  Discord = require("discord.js");

const client = new Discord.Client({ 
  intents: [
    'GUILDS','GUILD_MESSAGES','GUILD_PRESENCES'
  ]
});
