Calendar stuck at 'Loading...' after 2.1.1 update



  • So since the update I have had nothing but problems, first the black screen on boot (I managed to get rid of this somehow by running ‘git pull && npm install’ for a second time…

    Now however when I boot MM all of the modules load except the Calendar (default module).

    When I boot MM the following log is shown:

    MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
    If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues
    

    I have downloaded the master file from git and replaced the modules/default on the pi with these but no change.

    I know the calendar url is fine as when I access via web browser it downloads the .ics

    Can anyone help at all?

  • This has fixed my problem - thanks very much!



  • Did you alter the rrule files and set them to 1900 to make them work? I reviewed my Google Calendar private url ics file and it looks like it doesn’t go before 1970. Now when I have MM2 running (2.1.1) it doesn’t give me the 1970 error but continues to show “loading”. Is there a fix for using private url? It works in the previous MM that I have installed on a separate Pi that I have yet to update.



  • @Chadeus Replying to myself, but wanted this for the community.

    It was about fixing the rrule-alt file and I changed it from 1970 to 1900 per the above link. Specifically: /home/pi/MagicMirror/node_modules/rrule-alt/lib/rrule.js

    Change: ORDINAL_BASE: new Date(1900, 0, 1), /* changed from 1970 to 1900 */

    Also, I generated a fresh private url for my Google Calendar. Not sure if that plays into it or not, but it worked after the changes plus getting a new url.
