Socket io "Broadcast from anywhere"

[Stavros-Lyras]

I follow this guide Using socket.io
When emitting an event from the controller action, Socket.io does not receive the event.
My code

import type { HttpContextContract } from '@ioc:Adonis/Core/HttpContext'
import Config from '@ioc:Adonis/Core/Config'
import Model from 'App/Models/Entities/Project'
import Ws from 'App/Services/Ws'

export default class ProjectsController {
  public async index(ctx: HttpContextContract) {
    Ws.io.emit("test", "everyone");
    const {
      order = [{ column: 'updatedAt', order: 'desc' }],
      includes,
      ...filters
    } = ctx.request.all()
    let page = 'page' in ctx.request.all() ? ctx.request.all().page : 1
    let query = Model.filter(filters).orderBy(order)
    if (includes) {
      for (let i = 0; i < includes.length; i++) {
        query = query.preload(includes[i])
      }
    }
    const data = await query.paginate(page, Config.get('app.pageSize'))
    return data
  }
}

I need to use socket.io in my project and I follow this guide Using socket.io.
When emitting an event from the controller action, Socket.io does not receive the event.

Package version

adonis 5

Node.js and npm version

npm: 8.19.2
node: 18.12.1

Controller code

import type { HttpContextContract } from '@ioc:Adonis/Core/HttpContext'
import Config from '@ioc:Adonis/Core/Config'
import Model from 'App/Models/Entities/Project'
import Ws from 'App/Services/Ws'

export default class ProjectsController {
  public async index(ctx: HttpContextContract) {
    Ws.io.emit("test", "everyone");
    return ctx
  }
}

Socket service code

import { Server } from 'socket.io'
import AdonisServer from '@ioc:Adonis/Core/Server'

class Ws {
  public io: Server
  private booted = false

  public boot() {
    if (this.booted) {
      return
    }

    this.booted = true
    this.io = new Server(AdonisServer.instance!, {
      cors: {
        origin: '*'
      }
    })
  }
}

export default new Ws()

Socket code

import Ws from 'App/Services/Ws'
Ws.boot()

Ws.io.on('connection', (socket) => {
  socket.on('test', (data) => {
    console.log('test')
  })
})

Problem

When emitting event from controller action, the socket doesn't receive event
