Cannot find module '#server_functions'

chrisfr1976

Hi,
I’ve updated to the latest Version today using at first the update script. I have some trouble with the calendar display and the newsfeed. I just started a blank Mirror instance. A module #server_functions is missing. I don’t know how to fix that.

What I’ve tried so far is

getting serverOnly folder from the repo manually
switched manually again to master branch and reinstalled all node_modules
uses npm install manually

This is the log:

#server_functions is an alias for js/server_functions.js which is defined in package.json:

        "imports": {
                "#module_functions": {
                        "default": "./js/module_functions.js"
                },
                "#server_functions": {
                        "default": "./js/server_functions.js"
                }
        },

Because axios is the only diff your package.json should contain above lines.

I have no idea anymore (maybe corrupt sd card).

sdetweil

@chrisfr1976 can you do

Stop MagicMirror

cd -/MagicMirror
rm -rf node_modules
npm install

Start MagicMirror

npm start

Also, can you send me the
~/MagicMirror/installers/upgrade.log

My email is same user id as here, at gmail

sdetweil

I don’t see that error in my test of npm run server.

chrisfr1976

@sdetweil and @karsten13, I think I solved my problem.
In the beginning when I used the update script it stopped with the node-version but didn’t update. So I updated manually by using the original code from Node JS. So I installed node v22.20.0. Later I went again down to v22.18.0. Maybe this caused some trouble. But Maybe not. rm -rf node_modules and npm install I did already 3 times before.

But now I modified the calendarfetcher.js and newsfeedfetcher.js:

This was removed:

const { getUserAgent } = require("#server_functions");
const { scheduleTimer } = require("#module_functions");

and replaced by this:

const getUserAgent = () => "MagicMirror v2.33.0";
const scheduleTimer = (timerRef, interval, callback) => {
    clearTimeout(timerRef);
    return setTimeout(callback, interval);
};

No errors and Calendar/Newsfeed is displayed as before. I don’t know exactly if there are any new issues now but so far I’m happy.

sdetweil

@chrisfr1976 I’d really like to see the upgrade.log file
~/MagicMirror/installers/upgrade.log

Email to Me , same userid as here at gmail

chrisfr1976

@sdetweil Hey, no problem generally but I‘m out until Thursday. I‘ll send it then.

sdetweil

@chrisfr1976 when you have time

chrisfr1976

@sdetweil

Hi Sam,
After the update to MagicMirror v2.34.0 I had again this Cannot find module '#server_functions issue. See above.
I solved it again manually in the calendarfetcher.js and newsfeedfetcher.js with a relative path.

I replaced this:

const { getUserAgent } = require("#server_functions");
const { scheduleTimer } = require("#module_functions"); //only in newsfeed

with

const { getUserAgent } = require("../../../js/server_functions");
const { scheduleTimer } = require("../../../js/module_functions"); //only in newsfeed

This time your update script worked fine without any error.

Maybe I’m alone with this behavior, but now everything works fine again as before the update. If anyone else discovers this problem, the code above might help.

chrisfr1976

…and I’ll remove axios from my modules. This is causing this trouble.

sdetweil

@chrisfr1976 but that means you dont have the correct node version or dependencies

Down level npm, see imports in package.json

sdetweil

@chrisfr1976 can you send me ~/MagicMirror/installers/upgrade.log

Same userid as here at gmail

chrisfr1976

@sdetweil

I have the same. Except my reinstalled Axios library.

upgrade.log will follow.

@chrisfr1976 how are you launching MagicMirror?

chrisfr1976

@sdetweil
I use pm2 script:


sleep 21s
cd ~/MagicMirror
DISPLAY=:0 npm run start

sdetweil

@chrisfr1976 weird

Upgrade log looks great.

Can you change to
DISPLAY=:0 npm start

And try

Shouldn’t matter, but such is life
