Calendar Module not working with Google Calendar

[AnduriI]

I have a very similiar problem. I use two calendar modules, one with dates from the local waste pickup service and another one with multiple google calendars. The waste calendar works fine (so nothing with the module), but google gives errors. I copied out two of the google-calendars:

[03.01.2024 11:05.10.477] [ERROR] Calendar Error. Could not fetch calendar:  https://calendar.google.com/calendar/ical/XXXXX/basic.ics RangeError: Invalid time value

I don’t know what invalid time value means, maybe someone can help

@AnduriI you need the latest mm version which has a fix for the isostring problem

[AnduriI]

@sdetweil what do you mean with latest mm version? I did git pull && npm install, so I should have the latest…

[sdetweil]

@AnduriI can u chedck the actual version u have

cd ~/MagicMirror
grep version package.json

[AnduriI]

@sdetweil

/MagicMirror $ grep version package.json
        "version": "2.26.0",

[sdetweil]

@AnduriI bizarre.

can u turn on debug in config.js

add

,"DEBUG"

to the loglevel: list

then let’s use non pm2 to capture the info

pm2 stop all
cd ~/MagicMirror
npm start >somefile.txt 2>&1

wait til u think the error occurs
ctrl-q

to top mm

then look at the somefile.txt

search for the isostring

you should see dates=
for each event

the problem was the rule.between function which calculates the repeating events would return junk
I put in a filter to remove the junk.

anyhow, then remove the DEBUG
thing from config.js

and you can use pm2 to restart mm til we figure it out

if u can, send the somefile.txt to me via email
my userid here at gmail

@sdetweil wow I was not aware of all old events also being sent and parsed… from 5+ years ago. That’s a lot of entries… (more than 1500 only for my main calendar)
I sent the log via eMail to you.

[sdetweil]

@AnduriI yes, the ics holds all that junk

[sdetweil]

@AnduriI are u willing to share one of the trouble cal urls so I can debug?

send in a private chat. not via mail. after use I will delete the data and the chat.

[sdetweil]

@AnduriI also try this

cd ~/MagicMirror
npm install electron@28.1.1
