<![CDATA[Calendar issue with 2.7.1]]>After updating to the latest version ( 2.7.1 ) from 2.6.0, one of my subscribed calendar feeds no longer works. It has worked fine in 2.6.0.

Running on Raspberry Pi 3B - Raspbian Stretch. NodeJS version 9.11.2. Electron 3.0.13

Currently, the calendar module shows “No upcoming events” for this calendar feed. I know there are items there because I’m subscribed on my laptop and iphone. This is a feed for our school calendar.

In the error logs, I see the following:

TypeError: Cannot read property 'length' of undefined
    at eventDate (/home/pi/MagicMirror/modules/default/calendar/calendarfetcher.js:69:25)
    at /home/pi/MagicMirror/modules/default/calendar/calendarfetcher.js:90:22

My calendar config is as follows:

{
  module: "calendar",
  header: "School Calendar",
  position: "top_left",
  config: {
    wrapEvents: true,
    fade: false,
    timeFormat: 'absolute',
    dateFormat: 'ddd , MMM DD',
    getRelative: 0,
    urgency: 0,
    maxTitleLength: 25,

        symbol: "calendar",
        url: "https://www.ojrsd.com//site/handlers/icalfeed.ashx?MIID=11"
      }
    ]
  }
},

Anyone else come across this issue?

Thanks a lot, - this helped :-) , it is so much easier if things are done right straight from the beginning :-D

In addition I also found the root cause for above reported “EADDRINUSE” error.
Simple again: I have enabled MagicMirror autostart in /home/pi/MagicMirror/installers/mm.sh, but don’t see it since I use a Remote Desktop connection (RDP) that gives me a different X-Window in comparison to the native Raspberry desktop.
Now launching Magic Mirror a second time on a different desktop and the same port causes the issue.
Since I disabled MM autostart Magic Mirror boots up without these errors.
Maybe I should get back from XRDP and switch to the preinstalled VNC to avoid having multiple desktops.

Again, thanks a lot for your support :-)

pi@raspberrypi:~/MagicMirror $ pm2 list

 Use `pm2 show <id|name>` to get more details about an app

With this information I stop the MagicMirror by the following command: pm2 stop 0

pi@raspberrypi:~ $ pm2 stop 0

+------------------------------------------------------+
Use `pm2 show <id|name>` to get more details about an app

By surprise the running MagicMirror survives and I kill the Electron instance with kill
After the MagicMirror instance is terminated I relaunch MagicMirror again with npm start &
The funny thing is that the naughty EADDRINUSE message is gone by now, but the calendar is still not working:

pi@raspberrypi:~/MagicMirror $ npm start &

OK, as said above I have relaunched the mirror by npm start & and try to evaluate what is going on with pm2 list:

pi@raspberrypi:~ $ pm2 list
+------------------------------------------------------+

+------------------------------------------------------+
 Use `pm2 show <id|name>` to get more details about an app

It’s funny, pm2 list tells me that the Mirror has stopped, while it is still running, but I still do not recieve any Calendar updates.
What is wrong here?

Thanks for your comment.
First I changed the port as recommended in mm/config/config.js to 8081 and gave it a reboot.
After reboot and logon I checked the network connections by sudo netstat -lnptu:

pi@raspberrypi:~ $ sudo netstat -lnptu

I am surprised to see Electron already listening on port 8081, though I have not started the MagicMirror.
In the next step I launch Magic Mirror by calling: npm start &

Unfortunately I see again a EADDRINUSE message (port 8081):

Server started ...

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?

While the mirror is running I execute again sudo netstat -lnptu and get:

This is strange. The launch of the mirror npm start & tells me a multiple use of the port 8080 or 8081 (whatever it set in config.js) but netstat -lnptu does not know anything about a duplicate use.

As advised I also added below line right after if (event.type === “VEVENT”) { in ftp://192.168.178.36/home/pi/MagicMirror/modules/default/calendar/calendarfetcher.js

console.log("have event title="+event.summary);

Unfortunately the console outcome again is: “EADDRINUSE”

{ Error: listen EADDRINUSE 127.0.0.1:8080

ok, then something ELSE on your system is using port 8080… maybe a web server?

change the port number in mm/config/config.js to something else (8081 maybe)

			if (event.type === "VEVENT") {
         // console.log("have event title="+event.summary);

so, add the second line and then uncomment it… I must have added that fro debugging someone elses problem

Hi Sam,
the calendar entry I use for testing is the standard URL:

url: "webcal://www.calendarlabs.com/templates/ical/US-Holidays.ics"

As advised by you I searched up-and-down my calendarfetcher.js in:
/home/pi/MagicMirror/modules/default/calendar/calendarfetcher.js

I can find the following string: if (event.type === “VEVENT”) {
But I cannot even find substring to uncomment such like this: console.log("have or event title or
Hence there seems to be nothing to uncomment

I rather believe my issue has something to do with to many Electron instances that kill several moduls.
Maybe you have an idea for this:

  1. I boot up my raspberry 3b
  2. Execute ‘ps -a’ to check the running processes
  3. ‘ps -a’ returns ‘ps’ as the only running processes
  4. launching the mirror: ‘npm start &’
  5. the console tells me uncaught exception since EADDRINUSE is already in use:

magicmirror@2.7.1 start /home/pi/MagicMirror
sh run-start.sh

  1. Now I recheck my running processes and see *four instances of Electron. According to another thread it looks like I run two instances of MagicMirror in parallel, that have a conflict with each other and causing this EADDRINUSE message:

if u can send me your calendar entry url, I can look at it to see which event is causing this problem…
or u can uncomment the one line in mm/modules/default/calendar/calendarfetcher.js, line

				if (event.type === "VEVENT") {
         // console.log("have event title="+event.summary);

and restart the mirror

you will see the event summary in the pm2 log

there is an event which does not have a start date and time. i looked thru changes to the calendarfetcher code, and cannot see any change to this line of code since before 2017.

data={"type":"VEVENT","params":[],"uid":"42271","dtstamp":"20190414T114129Z","summary":"District Closed","class":"PUBLIC","status":"CONFIRMED","priority":"0","sequence":"0","duration":"P1D","last-modified":"20180523T131717Z","transparency":"OPAQUE"}

Quite similar with me. I have a fresh Raspberry installation on my Pi-3B, the only additional packages installed are vsftpd (FTP-tool) and xrdp (RDP-server to allow Windows Remote Desktop Connections). On this fresh installation I have installed MagicMirror² and default Weather- and News app are working fine receiving live data.
For some reason the calendar app does not work and I get the same error message for the calendar module as you in my log-file:

./home/pi/.pm2/logs/MagicMirror-error.log

ATTENTION: default value of option force_s3tc_enable overridden by environment.
TypeError: Cannot read property 'length' of undefined

I reinstalled from scratch on another SD-card with the same result.
