Sorry, I don`t know how to show the errors during startup :-(

sdetweil

@Volkae where does npm start output

if using pm2 tge

pm2 logs --lines=xxx

xxx is the number of most recent lines
default 15

probably 100 good start
note the output comes in 2 parts

@sdetweil
Not using pm2

I’ve upgraded to the latest MM Version

pi@magicmirror:~/MagicMirror $ grep version package.json
        "version": "2.31.0-develop",

And I still get this error

[2025-05-07 09:57:19.297] [ERROR] Error when loading MMM-PublicTransportHafas: require() of ES Module /home/pi/MagicMirror/modules/MMM-PublicTransportHafas/core/DepartureFetcher.mjs not supported.
Instead change the require of /home/pi/MagicMirror/modules/MMM-PublicTransportHafas/core/DepartureFetcher.mjs to a dynamic import() which is available in all CommonJS modules.

My module version:

Already up to date.

I do not know what else I can do or what I have missed

@p1lspeda

I just done a fresh install of the module and it works fine for me.

Just out of curiosity, did you do the following steps?

cd MMM-PublicTransportHafas
npm ci --omit=dev

@KristjanESPERANTO ) saw the below in the log, I am assuming it is nothing to be concerned about?

@p1lspeda said in MMM-PublicTransportHafas - Error when loading - DeparturFetcher.mjs:

I’ve upgraded to the latest MM Version

not really, 2.31.0-develop <> 2.31.0

KristjanESPERANTO

@p1lspeda How did you perform the MagicMirror update? Please show us the output of git branch when you are in the MagicMirror root directory.

sdetweil

@KristjanESPERANTO looks like he was on the dev branch for a fix and didn’t use my script to update or follow the instructions I posted

https://forum.magicmirror.builders/topic/19561/version-2.31.0-april-1-2025-upgrade-reminder

@KristjanESPERANTO
Thanks for your patience,

Edit: did a complete reinstall and now it works. I must have misconfigured something and could not remember what or how.

The error still occurs.
At this point I’m completely clueless

Hello together,

i tried your instruction and updated MM and node.

My node Version is 23.7.0
My MM Version is 2.31.0
git branch shows me master (highlighted)

I also updated the module Version to: “3.1.11”

Still got the error message.

sdetweil

@Vulan12354 how did you upgrade MagicMirror?

sdetweil

@p1lspeda on my upgrade script, can you show me the ~/MagicMirror/installers/upgrade.log

or tell me the command you used

p1lspeda

@sdetweil
I removed the entire MagicMirror directory before reinstalling MM.
I didn’t make a backup, so I cannot provide the log. Sorry.

For updating I tried

bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)"

and

bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)" apply

and the fresh install was achieved by using

bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh)"

sdetweil

@p1lspeda great thanks…

only THIS one DOES the upgrade

bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)" apply

BUT, if you did a git pull manually then the local code would be at the new/current version
and I would abort, as you are ALREADY at the current level…

THEN you have to do

bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)" force

cause I won’t let you upgrade OVER the same release accidentally

~/MagicMirror/installers/upgrade.log is created and updated in all cases.
so we can tell what happened

if it didn’t seem to work, I want to know… and get the log,
even if you decide to abort and start over

these scripts are very conservative… I do NOT want to destroy your running MM system

p1lspeda

@sdetweil
good to know for the future. Thanks.
I was unaware of the “force” parameter, that’s why I never tried it.

sdetweil

@p1lspeda i do not publish force, as i do not want people to use it willy nilly.

danger…

Vulan12354

@sdetweil

It looks like it is working now, but at the moment the module cant get any information about the bus schedule. But the MagicMirror is starting without any error message.

Thank you for your patience.

I will wait till monday, and tell you all if its working now or not.

Vulan12354

Hey together,

it is working now.
The last bug was a known issue.
