Duplicate Answer ami.on

[fabiotheo]

i Have a problem, this code generates duplicate responses when I run twice, and tripled responses when I run three times... why?

`const express = require('express');
const server = express();
server.use(express.json());

const porta = '1000';
const host = 'mypbx.pbx.com';
const login = 'pbx';
const password = 'pbx123';

server.use((req, res, next) => {
console.time('Request');
console.log(Metodo: ${req.method}; URL: ${req.url});
next();
console.timeEnd('Request');
});

server.get('/clicktocall', (req, res) => {
const { key,from, to, deal_id, person_id } = req.query;

const ami = new require('asterisk-manager')(porta,host,login,password, true);
ami.keepConnected();

ami.on('managerevent', function (evt) {
    if (evt.event === 'OriginateResponse') {
        console.log(evt);
    }
});

ami.action({
    'action':'originate',
    'WaitTime':'300',
    'channel':'SIP/9007',
    'context':'default',
    'exten':'45991086495',
    'Callerid':'9007',
    'priority':'1',
    'timeout':'30000',
    'Async':'true',
}, function(err, res) {
    console.log('action callback: ', err, res);
});


return res.json({ key: key, from: from, to: to, deal_id: deal_id, person_id: person_id});

});`

This is the response received:
