@sdetweil I deleted the bad event in outlook and added a new google calendar with that occurrence series in order to subscribe it againg with my outlook cal…

@sdetweil ok, sounds nasty… I recognized in my debug-logfile that those custom time zones were converted correctly. Just the null values were the problem. Fixed for me now…

@sdetweil sorry for the wrong reply, it refers to @spitzlbergerj …

My local TZ seems to be right, but it don’t know, why there are these null values in the array. I subscribed my outlook calendar in another google calendar and it worked. These appointments are also rightly displayed in my iPhone, just by subcribing the outlook cal.

@sdetweil I just use Putty to connect via ssh. It won’t open a new window. You can check on your mirror or in browser, whether the mirror is loading the modules. When the error message appeared, I canceled the script via crtl + c. Then you have to search a bit in your logfile e.g.

cat /pathtoyourfile/somefile.txt

in order to figure out where the wrong appointments are. In my case it was more or less easy because the RangeError and the null-values in the array were very noisy.

thanks, I found the wrong calendar entry!
I have inserted a recurring event that seems to have been converted by Outlook as a wrong Customized Time Zone…

Suddenly after several months of a successful usage of my outlook calendar and the calendar-module a bug. Maybe somebody knows a suitable solution?

also adding some lines of code didn’t fix the issue https://forum.magicmirror.builders/topic/15803/error-moment-timezone-has-no-data-for-customized-time-zone/6?_=1651432649589&lang=de
