MMM-JAST stopped updating a couple of days ago.

Ok, after git pull, had to do a npm ci and that fixes it!

Hi, I’m stuck at “Loading…” on this module as well. This is a new build I’ve been working on in the last week or so, first timer with MagicMirror so hopefully I’m not missing something obvious. I’ve not been able to get MMM-Jast to display any values at all, but I can get other modules working no problem.

I’m running the latest 2.10.3 version and I’ve removed and reinstalled it a few times, as well as completely reloaded my raspi device from scratch, but no luck. pm2 logs don’t show any errors, but I’m unsure what other logs to evaluate.

Here is my config. I’ve tried a bunch of different config options to see if anything kicks it into gear, including a completely bare config with just the example config from the README, but each attempt just shows “Loading”.

    {
      module: "MMM-Jast",
      position: "middle_center",
      config: {
        displayMode: "none",
        stocks: [
          { name: 'DJIA', symbol: 'DIA' },
          { name: 'SP500', symbol: 'VOO' },
        ]
        },
    },

@vgardenn Interesting. Your config works on my system.

Please show us your system information (you can see it when you run npm run start) - and looks like this:

@KristjanESPERANTO Here is my system info from the npm run start output:

This also highlighted an error I may have been missing in the pm2 logs output, so it may not be a module issue at all. I apologize if I had you looking at this and it was just an issue with my MM setup. I’ll start researching what this error means:

[2026-01-19 18:14:54.626] [ERROR] [app] WARNING! Config file appears empty, maybe missing module.exports last line? 
[2026-01-19 18:14:54.627] [ERROR] [app] WARNING! Could not load config file. Starting with default configuration. Error found: TypeError: userConfig.modules is not iterable

@vgardenn show the last 5 lines of config.js
Compare to the sample in the same folder

What is this?

userConfig.modules

vgardenn

I’m unsure what that userConfig.modules is, from my googling it seems maybe related to node.js?

Here is the entire config.js. The last 5 lines look similar to the sample config:

let config = {
  modules: [
    {
      module: "MMM-MagicMover",
    },
    {
      module: "clock",
      position: "top_bar",
      config: {
	timeFormat: 12,
	displaySeconds: false,
	dateFormat: "dddd, MMMM D",
        }
    },
    {
      module: "weather",
      position: "top_center",
      config: {
	weatherProvider: "weathergov",
        type: "current",
	tempUnits: "imperial",
	roundTemp: true,
	showFeelsLike: false,
	colored: true,
	showSun: false,
	lat: "xxxxxx",
	lon: "xxxxxxx",
        }
    },
    {
      module: "MMM-Jast",
      position: "middle_center",
      config: {
	displayMode: "none",
	stocks: [
	  { name: 'DJIA', symbol: 'DIA' },
	  { name: 'SP500', symbol: 'VOO' }
	]
        }
    },
    {
       disabled: true,	
       module: "MMM-NowPlayingOnSpotify",
       position: "bottom_center",
       config: {
       	 showCoverArt: false,
         clientID: "<YOUR_CLIENT_ID>",
         clientSecret: "<YOUR_CLIENT_SECRET>",
         accessToken: "<YOUR_ACCESS_TOKEN>",
         refreshToken: "<YOUR_REFRESH_TOKEN>"
    	 }
    },
  ]
};

@vgardenn these lines are not at the bottom of your config file

/*************** DO NOT EDIT THE LINE BELOW ***************/
if (typeof module !== "undefined") { module.exports = config; }

Typically to start your MagicMirror journey
You copy the sample and edit the copy for your use

vgardenn

Well you called it correct, I did not start with the sample config and adding that missing line at the end of my config got this mod working as expected. I had grabbed the example config from documentation here assuming it was good enough and was off to the races.

Thank you very much for your help on this @sdetweil and @kristjanesperanto

sdetweil

@vgardenn cool. We’ll fix that

The MagicMirror install doc says
