Error: Cannot find module 'node:fs'

[Husband]

Hi folks, I have a pretty vanilla config of MagicMirror running in a container stack on Portainer and have suddenly started to get the following error when starting the container:

[21.11.2025 10:52.25.515] [ERROR] Error: Cannot find module 'node:fs'

}

I’ve not made any intentional changes to the environment (I know, I know) and this suddenly began yesterday. I’ve not modified anything in the modules or config directories. I haven’t touched this env in 3 weeks and its been running fine.

Here is my docker compose:

version: '1'
services:
  magicmirror:
    container_name: magicmirror
    image: bastilimbach/docker-magicmirror
    #restart: unless-stopped
    environment: 
      - PUID=1035 # magicmirror user on Synology
      - PGID=100
      - TZ=America/Toronto
    volumes:
      - /volume1/docker/magicmirror/config:/opt/magic_mirror/config
      - /volume1/docker/magicmirror/modules:/opt/magic_mirror/modules
    ports:
      - 8888:8080

I have watchtower running, but there haven’t been any updates to this image since it was deployed a couple of months ago.

@Husband i do not know… that container is fairly old…
I use the one from karsten13
https://khassel.gitlab.io/magicmirror/

he is away for a few days.

@sdetweil thank you for the tip. I’ve at least got things running again with this image. I’ll need to make some adjustments to get things working 100% but at least the container starts and runs now.

Very strange, since there didn’t appear to be any updates to the old image I was using.
