Something went wrong displaying this web page error

kellogg76

Everything has been running well for a few months, a couple of weekends ago I noticed a message on the screen informing me that updates were available so I did a git pull in the MagicMirror folder then npm install.

Everything seemed to have gone well, but after about 15 minutes the screen gives me a “Something went wrong displaying this web page error”. If I use VNC to login in and reload the page everything loads, and I can also load the MagicMirror from other computers on my network but it always goes back to the same error after a period of time.

I’m using a Pi Zero if that helps with any suggestions.

@kellogg76 is pm2 used to start mirror app?

if so, pm2 logs --lines=100
might show the error

if u have modules that have a package.json file, they also needed an npm install done in their folders too…

my upgrade script handles all that
see here https://github.com/sdetweil/MagicMirror_scripts

Your updater script doesn’t work on a Pi Zero.

I’ll try running npm install in the three non default module folders.

Thanks

@kellogg76 >Your updater script doesn’t work on a Pi Zero.

say what? i have tested on pi 0, 3, 4, odroid, jetson nano, and mac.
a bunch of folks have tested on all kinds of pi’s…

show me the log, ~/MagicMirror/installers/upgrade.log

just for clarity the , updater doesn’t do anything by default except test the upgrade

if u want it to DO the upgrade, u have to add the parm at the end ‘apply’

from https://github.com/sdetweil/MagicMirror_scripts

it should handle all the work… and give you a trial run of all that…

only applying changes if u request them

give it a try this works on Mac as well

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

no changes are made to the local repo or the working copy

if you WANT to actually apply the changes do

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

Apologies, when I ran

curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/raspberry.sh | bash

I stopped reading after “Sorry, your Pi is not supported”, I just re-ran it and see the bit about Pi Zero’s.

The install log is as follows

It doesn’t appear there are any updates to apply as far as i can tell.

@kellogg76 said in Something went wrong displaying this web page error:

which means you didn’t add

apply

to the end to actually DO the upgrade
like this

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

upgrading from version 2.10.1 to 2.10.1

correct

u can do force instead of apply to redo the upgrade

like this

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

kellogg76

@sdetweil

I’ll give it a try with the force option.

Thanks

kellogg76

@sdetweil

Unfortunately it doesn’t seem to have made any difference.

sdetweil

Ok, we/I made a change to how the mirror app starts on pi 0 or other armv6l systems.

But I introduced a bug. Download the fixed run-start.sh like this

cd ~/MagicMirror
curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/run-start.sh > run-start.sh

Then start the mirror app again

kellogg76

@sdetweil
Still the same error after doing the above and then rebooting.

sdetweil

@kellogg76 ok, some module did not get updated with the new mm.

Can you do

cd ~/MagicMirror
node installers/dumpactivemodules.js

This should return a list of modules that have package.json files

kellogg76

@sdetweil said in Something went wrong displaying this web page error:

node installers/dumpactivemodules.js

When I do that nothing appears on screen

sdetweil

@kellogg76 ok

Then do this

ls ~/MagicMirror/modules

kellogg76

@sdetweil
The only non-default modules I have are
MMM-BackgroundSlideshow
MMM-DarkSkyForecast
mmm-suncalc

I’m going to remove them one by one from the config and see if that identifies which is the problem module.

Edit: it looks like it’s the BackgroundSlideshow module, removing that from my config file makes everything stable again. Thanks for your help.

sdetweil

@kellogg76

ok, great feedback

I was wrong before

cd ~/MagicMirror/modules
node installers/dumpactivemodules.js

this will list off all the modules which are active in config.js

i would go the the MMM-BackgroundSlideshowfolder and do

npm install

sdetweil

@kellogg76 also, the first script u listed is raspberry.sh which is new install.

Upgrade-script is the one that does version upgrades of existing installations (get rid of that message)
