@sdetweil first I updated manually, but like said after troubleshooting now I have completely new installation via the script and still not working properly even with sample config.

[sdetweil]

@ereborinkorppi weird

do show output of

node -v
npm -v
lsb_release -a

[sdetweil]

@ereborinkorppi also show the output of npm start

@ereborinkorppi ok, both in 64 bit mode

we disable GPU in 2.26 by default now…
so none of those messages should be happening…

[ereborinkorppi]

@sdetweil I accidentally removed the post for npm start output and have been waiting for it to be re-posted, but it is still in the post queue. I have no idea what to do next? Should I re-install 32 OS instead and try to run the MagicMirror install script again or install an older MagicMirror version that used to work?

[sdetweil]

@ereborinkorppi I was waiting for you to respond… and u did… so I just rejected the post that was marked as spam. like my message should have said

[sdetweil]

@ereborinkorppi it would be interesting to see the 32 bit results…

[ereborinkorppi]

@sdetweil I will give it a go if no easier solutions available, but will take some time before I can test it. Thank you so far, will report later what happened.

[sdetweil]

@ereborinkorppi i just don’t know… we are not using GPU, that error is related to GPU.
says happening in chromium, but we are not using chromium… so… at a loss.

I see it on my pi3 in 32 bit mode, but it doesn’t stop mm…

[sdetweil]

@ereborinkorppi sorry I hit the reject button, can u resubmit.

@sdetweil
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

[eyesallin]

@sdetweil
Thx for responding, the only errors are

[MMM-OpenWeatherMapForecast] 7-Jan-24 09:08 ** ERROR ** null

@eyesallin said

[MMM-OpenWeatherMapForecast] 7-Jan-24 09:08 ** ERROR ** null

yeh not very useful, but there was an error

[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

[ereborinkorppi]

@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.
