cannot reproduce xxxplatform example with slack and messenger

[glare1062]

The connections work individually
but dont mesh together like in the example
and i used a Ngrok server to test

• so when i tried Messenger alone i get a response
• but when i combine them like in the example i only get slacks object output
• and messenger gives me an error

please advice cuz im quite new to node and angular
My Code :

const` Rx = `require("rxjs/Rx");
const R = require("ramda");


const BroidSlack = require("@broid/slack");
const BroidMessenger = require("@broid/messenger");

const FACEBOOK_ACCESS_TK = "EAACyaH0LpzJVuqJz4sBMZCyqpxZBKxvsz7MiLPcHGMKXZAotQsyCJN16VBLJ7rFv1ykdR2urZCmoRgNvjmRLWbHcsAR59KpcC7c3oEZBVEEpJgjT2I07BbPwb2xxpMzEWYEJik3B2R7fhJNCc4jmg3ZAb4N102yCO5ksZCkAZCQ1VIhZBeDq7ZACW4ZD" ;
const VERIFY_TK = "broidtestbot" ;

const clients = {

  messenger: new BroidMessenger({token: FACEBOOK_ACCESS_TK ,
  tokenSecret:VERIFY_TK ,
    http: {
    host: '0.0.0.0',
    port: 5000
  }}),  
  slack: new BroidSlack({token: 'xoxb-389-387469850096-Iz6XwU4u7io4dt8XhdwTkiSR',
    http: {
    host: '127.0.0.1',
    port: 5000
  }}),
 
};
console.log('point 2 rite before the merge calling');
Rx.Observable.merge(...R.map(client => client.connect(), R.values(clients)))

Rx.Observable.merge(...R.map(client => client.listen(), R.values(clients)))

.subscribe({
  next: data => console.log(JSON.stringify(data, 1, 3)),
  error: err => console.error(err),
});`

Error (only occurs when i try to send something from messenger) :
