console.log not fired when promise is executed - node.js

Question

I have a js file in which i export a promise and i call it in another file.
I dnt understand why the console logs are not fired when i call the promise,
maybe i dnt fully understand how promises work or maybe sth is wrong with the way i call the promise
pub.js
var config = require('../config');
var q = 'tasks';
var open = require('amqplib').connect('amqp://'+ config.rabbitmq.url);
module.exports = open.then(function(conn) {
return conn.createChannel();
}).then(function(ch) {
return ch.assertQueue(q).then(function(ok) {
console.log('inside publisher')
const r = ch.sendToQueue(q, Buffer.from('something to do'));
console.log('r',r)
return r
});
}).catch(console.warn);
index.js (where i call the promise)
var express = require('express');
var router = express.Router();
var publisher = require('../connectors/pub');
var rabbitPromise = () => (
new Promise((resolve,reject)=>{
publisher
.then(res=>{
console.log('-----------------------')
console.log('publishing now',res)
resolve(res)
})
})
);
/* GET home page. */
router.get('/', async(req, res, next) => {
const result_pub = await rabbitPromise()
res.send('ok')
});
I expected to see the console.log('inside publisher') but i don't see it i only get console.log('-----------------------') and console.log('publishing now',res),

Answer 1

the chaining in pub.js is not right. In order to call the promise, it would be something more like this :
module.exports = open
.then(function(conn) {
return conn.createChannel();
})
.then(function(ch) {
return ch.assertQueue(q);
})
.then(function(ok) {
console.log('inside publisher')
const r = ch.sendToQueue(q, Buffer.from('something to do'));
console.log('r',r)
return r
})
.catch(console.warn);
