MQTT module stopped working with latest update

Hi All, I've been using the MQTT module without any problems for at least a month. However, I started having problems yesterday, which I see was the day that a new MQTT module was posted on https://www.espruino.com/modules

mqtt.connect() gives this immediate error:

>mqtt.connect()
=undefined
Uncaught SyntaxError: Got ':' expected EOF
 at line 1 col 70
...;var f=c.charCodeAt(0)>>4;a:{var d=c.substr(1,5);var k=1,l=0...

Code is running on
ESP8266-12E flashed with espruino_1v95_esp8266_4mb_combined_4096.­bin ...

Test program, which has worked without a problem is listed below.

Is there an error in the MQTT module? Is there a change in using it?
Also, a related question: is there a way to access a previous version of a module?

Thanks,

Dan

Program:

var wifi = require("Wifi");

  var server = 'm14.cloudmqtt.com';
  var options = {
          keep_alive: 60,
          port: xxxx,
          clean_session: true,
          client_id: "xxxx",
          username: "xxxx",
          password: "xxxx",
          protocol_name: "MQTT",
          protocol_level: 0 };

  var mqtt = require("MQTT").create(server, options); // changes here
    mqtt.on('connected', function() {
    mqtt.subscribe("red");
      mqtt.subscribe("blue");
    console.log("connected");
  });

mqtt.on('disconnected', function() {
  console.log("MQTT disconnected... reconnecting.");
  setTimeout(function() {
    mqtt.connect();
  }, 1000);
});
  
   mqtt.on('publish', function (pub) {  // this place throw error
    console.log("topic: "+pub.topic);
    console.log("message: "+pub.message);
    if (pub.topic == "red") {
     if (pub.message == "on") {digitalWrite(16,0);}
     if (pub.message == "off") {digitalWrite(16,1);}
    }
      if (pub.topic == "blue") {
     if (pub.message == "on") {digitalWrite(2,0);}
     if (pub.message == "off") {digitalWrite(2,1);}
    }   
  });

function onInit() {
  console.log("In onInit");
  wifi.connect("xxxx", {password:"xxxx"}, function(err){
console.log("connected? err=", err, "info=", wifi.getIP());
});
wifi.stopAP(); 
mqtt.connect(); 
}

Update: I found how to go back to a previous version from github (instructions at https://www.espruino.com/Modules). With the previous version of the MQTT module, I have no problems.

Hi Dan,

Thanks - I'll look into it. I merged on some contributed changes which could have caused problems.

Wow, that's horrible. Looks like the Closure compiler that I use for minification has started adding labels and breaks to labels into minified code - which meant that the unminified file worked fine, but the minified version didn't.

It should be fixed now.

Actually hang on a bit. Looks like the recent contributed fixes broke the module (so it strips the first 2 chars off the message), so I'll have to roll back some of them

Ok, try now :/

Hi Gordon,

Works! Thanks so much. BTW, I've been working with microcontrollers for 40 years (starting with the 6502, assembly, and FORTH); and I have to tell you, Espruino on the ESP8266 is the best thing I've ever worked with in this realm. Espruino is an awesome system! Thank you for developing it.
Dan

Thanks! :)
