Calendar shows "no entries" after MM Update

[Peter_van_Evert]

Hello everybody,
the MM works fine, everything was shown and so on. After installing the update 2.1.1 the calender module shows that there were no entries in the calendar, but there are a lot. I controlled the config file - everything ok. I updated the Raspi - the error is already there. Can anyone help me ? The Calendar is very important for me.
Thanks
Peter

Did you try to reload your MagicMirror? From time to time I experience the same trouble with an outlook.com calendar. Reloaded the MagicMirror (refreshing the website) - some times several times - resolves this.

Hello yawns,
thanks for your fast answer. But I tried several times. Start the Raspi new, start the MM with Control-R , but the error is the same. First it displays “load” over a long time and then it displays “no entries” (Keine Termine - because I’m german).

Ok. Could you try to copy the url of your calendar config and paste it into any browser to see if this loads?
Did you try to stop the magicmirror process, start it with npm start dev and look for any error entries in console?

[Peter_van_Evert]

Hello yawns,
the url is a google calendar ics url and when I paste the url in my browser it load.
This are the error Messages after i type npm start dev.

[yawns]

you are in the wrong directory, you need to change with cd MagicMirror
Are you working on your pi? Or are you connected via ssh? If you use ssh then you need to run DISPLAY=:0 npm start dev instead

Hello yawns,

this are the Terminal messages after i follow your advice. I log into over ssh.

@Peter_van_Evert take a look here https://forum.magicmirror.builders/topic/2209/error-listen-eaddrinuse-help-plox

Thank for your help but I think there is no other Application who listen on 8080. This is the result on your idea and I think electron.js is an app of MagicMirror isn’t it ?

[strawberry 3.141]

@Peter_van_Evert yes, but this shows that there is an instance of MagicMirror still running, if you dont know how to kill it the easiest solution would be to restart the pi

[Peter_van_Evert]

and before I install the Update of MM, everything works fine.

[Peter_van_Evert]

@strawberry-3.141 what do you think is the second instance of MM ? There’s only one who listen on 8080 and when I kill this app, my MM close.

I am having the same issue. I have multiple calendars in one view and after the update one will not show up and there are current events on that calendar.
I luckily had backed up my sd card before updating so I just went back to the prior version. This was after troubleshooting multiple items to get the new update to work.

Same here, I have two ICS from google calendar, on (from my wife) works fine (when I download ICS it’s 300Kb) and mine doesent work (download of ICS is 1.3MB)

I mentioned this in another post, but I am seeing the same behavior described here.

[jasondreher]

We need troubleshooting with this! Who can help? My MM was fantastic before the update.

Hello everybody - I know now, that the problem with the google calendar is. As sacha81 wrote : a small calender will be displayed, a big one ( my is 850k) not !! I tested it with a new calendar with 10 entrys. Is there a way to get the old version back ? The calendar is for me the most important item in the magic mirror. Nobody needs a buggy version of MagicMirror.

[jasondreher]

That makes sense, the only calendar that does not show is my largest one. And most important!!

[Peter_van_Evert]

Hello everybody. I come with very good News ! I find a solution without the people from MagicMirror.

1. My old google calendar was too big (850k) and I search earlier for a solution to delete my old calendar entries in the google calendar, e.g. everything before 2017, but there were no function or button at google.
2. I export my old and heavy ics File from google to my Computer.
3. I wrote a short python script, which takes the ics header from my ics file, delete everything that is older than 2017 and ended with the original ending from my ics file. The new file is 85k :)
4. I create an test calender to import the ics file - everything is ok.
5. I delete every !! entrie in my Maincalender (my heart goes up) and import the new light ics file - everything goes fine and the new calendar is shown in the MM calendar.
6. Delete the test calender
   Another nice thing is, that there are now no old datas in the google calender. For further information, just contact me.
   Yours
   Peter

Thank you Peter for this idea, it will help to mitigate the issue. But this is only a workaround and not a solution, I want to keep my old entires …
