multiple error in magic mirror after update from 2.28.0 to 2.36.0

sdetweil

@1a2a3a your Linux/pi system uses a window manager to display the app session window on the screen

In the past it was just x11 (xwindows)
In the last couple years a new thing has appeared , Wayland

We need two different commands to tell which wm is active

If you look in the terminal window where you did the command above, you will see the debug output that will identify the module

Here is mine for punycode

[2026-04-08 19:03:13.384] [INFO]  [helpers] [MMM-HomeAssistantDisplay] [ 'HomeAssistant connected for module_20_MMM-HomeAssistantDisplay' ]

    at node:punycode:7:10

So MMM-HomeAssistantDisplay is the module that is causing the message

sdetweil

@1a2a3a no, if it works w npm start, leave it alone

1a2a3a

@sdetweil it didnt show any module error.

@sdetweil my pm2 is currently not working at the moment.

i then tried to pm2 start and ran into this error. Ok not exactly error, but the mirror just keep going to blackscreen and nothing then back to wall paper then blackscreen and keep looping this.

sdetweil

@1a2a3a you did this right?

NODE_OPTIONS=--trace-deprecation npm run start:xxx

Replace xxx with x11, the whole line
On your system

That’s 2. — in front of of trace-deprecation

1a2a3a

@sdetweil yes correct

NODE_OPTIONS=–trace-deprecation npm run start:x11

i also manually git pull all the modules and all are up to dates as well.

1a2a3a

@sdetweil how do i fix my pm2 issue?

sdetweil

@1a2a3a need 2 dashes in front of trace

sdetweil

@1a2a3a change the npm start to npm run start:x11

If you had used my upgrade script it would have fixed that

1a2a3a

@sdetweil i did use your upgrade script.

do you mean change it inside mm.sh?

currently its

#!/bin/bash
# This file is still here to keep PM2 working on older installations.
cd ~/MagicMirror
DISPLAY=:0 npm start

change it to

#!/bin/bash
# This file is still here to keep PM2 working on older installations.
cd ~/MagicMirror
DISPLAY=:0 npm run start:x11

correct?

sdetweil

@1a2a3a correct…

in version 2.35 we documented that we changed the default to

npm run start:wayland

for npm start

see package,json, scripts: section for the command options

1a2a3a

@sdetweil same thing

NODE_OPTIONS=--trace-deprecation npm run start:x11

@sdetweil i have change my mm.sh to

#!/bin/bash
# This file is still here to keep PM2 working on older installations.
cd ~/MagicMirror
DISPLAY=:0 npm run start:x11

but when i do pm2 start MagicMirror, it doesnt start still.

sdetweil

@1a2a3a SO much fun

do this and give me the output

grep "module:" ~/MagicMirror/config/config.js | sort | uniq

and I’ll look thru them

1a2a3a

@sdetweil here you go

[hsa@HSA:~ $ grep "module:" ~/MagicMirror/config/config.js
                        module: "alert",
                        module: "updatenotification",
                        module: "clock",
        module: "MMM-Jast",
  module: 'MMM-GoogleDocs-Notes',
                        module: "newsfeed",
                module: "MMM-NewsAPI",
  module: "MMM-MyScoreboard",
  module: "MMM-SoccerLiveScore",
//  module: "MMM-GooglePhotos",
// module: "MMM-ImagesPhotos",
//   module: "MMM-Wallpaper",
//    module: 'MMM-BackgroundSlideshow',
  module: "MMM-OneDrive",
  module: "MMM-CalendarExt3Agenda",
                        module: "calendar",
                         module: "MMM-CalendarExt3",
                        module: "calendar",](link url)

sdetweil

@1a2a3a ok, I didn’t find it the easy way

lets try the easier way

find ~/MagicMirror/modules -type d | grep punycode | sort

each module listed has it as a dependency either directly or indirectly
on my system (with a lot of modules installed, but most not used)

/home/sam/MagicMirror/modules/Hello-Lucy/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-BMI/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-CalvinAndHobbes/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-FinParcel/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-GoogleCalendar/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-HomeAssistantDisplay/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-homeassistant-sensors/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-json/node_modules/npm/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-json/node_modules/npm/node_modules/uri-js/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-json/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-Lottery/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-MARS/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-NOAA3/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-OnSpotify/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-Reddit/node_modules/psl/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-Reddit/node_modules/request/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-Reddit/node_modules/uri-js/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-SmartWebDisplay/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-Strava/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-Surf/node_modules/punycode
/home/sam/MagicMirror/modules/MMM-Todoist/node_modules/punycode

because its not listed in one of the modules directly, its a dependency of a dependency

1a2a3a

@sdetweil can we fix the pm2 please?

sdetweil

@1a2a3a use my mm.sh

#!/bin/bash
cd ~/MagicMirror

if [ $(ps -ef | grep -v grep | grep -i -e xway -e labwc | wc -l) -ne 0 ]; then 
   # if WAYLAND_DISPLAYis set, use it, else set to -0
   export WAYLAND_DISPLAY=${WAYLAND_DISPLAY:=wayland-0}
   npm run start:wayland
else
   DISPLAY=:0 npm run start:x11
fi

@sdetweil

hsa@HSA:~ $ find ~/MagicMirror/modules -type d | grep punycode | sort
/home/hsa/MagicMirror/modules/MMM-Jast/node_modules/punycode

@sdetweil it doesnt work still unfortunately. it goes into a black screen then back to wallpaper and keep looping in this manner…
