Failover Transport Errors

[TheRhinoFans]

I am using Amazon MQ with failover, which is really multiple Apache MQ instances. Apache MQ has a failover transport ( https://activemq.apache.org/failover-transport-reference.html ) but it seems to me that mqtt.js doesn't support this feature. Would that be correct?

// NodeJS Example
const mqtt = require('mqtt');
const user = 'mqtt_user';
const pass = 'mqtt_pass';

const aws1 = `wss://${user}:${pass}@111111.mq.us-west-2.amazonaws.com:61619`;
const aws2 = `wss://${user}:${pass}@222222.mq.us-west-2.amazonaws.com:61619`;

const host = 'failover:(' + aws1 + ',' + aws2 + ')';

const options = { keepalive: 60, protocolId: 'MQTT', protocolVersion: 4, clean: true, reconnectPeriod: 1000 }; 

var client = mqtt.connect(host, options);
client.on( "connect", e => console.log('success') );
client.on( "error", e => console.log('failed\n', e) );

// Errors Returned

}

// NodeJS Example
const mqtt = require('mqtt');
import { IClientOptions } from 'mqtt';

const user = 'mqtt_user';
const pass = 'mqtt_pass';

let options:IClientOptions = {
    username: user,
    password: pass,
    clientId: uuid(),
    servers: [
        {
            host: '//111111.mq.us-west-2.amazonaws.com',
            port: 61619,
            protocol: 'wss'
        },
        {
            host: '//222222.mq.us-west-2.amazonaws.com',
            port: 61619,
            protocol: 'wss'
        }
    ]
  };

var client = mqtt.connect(options);
client.on( "connect", e => console.log('success') );
client.on( "error", e => console.log('failed\n', e) );
