Hi I’m a nooby, I’m seeing the same errors in my startup but MM still runs OK. The only reason I found it was because I can’t get the MMM-OpenWeatherMapForecast to display just says loading?
I’m wondering now if the error has nothing to do with module running.

[sdetweil]

@eyesallin do you see any errors from openweathermapforecast in the place you start mm

@sdetweil
Thx for responding, the only errors are

[fethiyetours]

Thanks for information

[sdetweil]

@fethiyetours can u edit the module node_helper.js and change the error path like this

                    } else {   /// this is the current line 62
                        if(response.statusCode != 200)
                            console.log("[MMM-OpenWeatherMapForecast] " + moment().format("D-MMM-YY HH:mm") + " statusCode " + response.statusCode);
                        else 
                            console.log("[MMM-OpenWeatherMapForecast] " + moment().format("D-MMM-YY HH:mm") + " ** ERROR ** " + error);
                    }

I’m guessing the statuscode will be 401, unauthorized

@sdetweil sorry for the delay. I guess I posted about my 32bit test. So I installed new 32 os and MagicMirror with the script, nothing extra, no own settings. Still gives me the same error message, and like for others here it doesn’t load the weather module (in sample config file) without any extra errors. If I switch to my own config (without any 3rd party modules) it doesn’t load all of my calendars (no other errors than the gbm_wrapper) and the whole MagicMirror gets stuck. Can’t even quit it without killing it.

[sdetweil]

@ereborinkorppi I see that error on my pi too, but it doesn’t interfere with operations.

would you be willing to to do a backup of your system using my backup/restore scripts

https://github.com/sdetweil/MagicMirror-backup-restore

and send me the three files. to my email,
sane userid as here at gmail

config.js, custom.css and the module list

to email js files you have to rename to .txt

@sdetweil Wondering if there was a resolution here. I just did a brand new install on a Pi4b v1.5 using the script. I’ve not added any modules or changed the default config file in any way.

During the setup, I saw this (probably unrelated)

/usr/lib/aarch64-linux-gnu/plymouth/.so does not exist
Splashscreen: Couldn't change theme to MagicMirror!
don't know how to disable screen saver on labwc compositor

I added the

export ELECTRON_DISABLE_GPU=1

to the mm.sh
but had no effect.
I noticed this in the log

ELECTRON_ENABLE_GPU: undefined .

and tried adding

export ELECTRON_ENABLE_GPU =0

but it had no effect except to change the “undefined” to “0”
