      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
          at Request._callback (/home/pi/MagicMirror/modules/default/calendar/vendor/ical.js/node-ical.js:11:5)
          at Request.self.callback (/home/pi/MagicMirror/node_modules/request/request.js:185:22)
          at Request.emit (events.js:182:13)
          at Request.<anonymous> (/home/pi/MagicMirror/node_modules/request/request.js:1157:10)

          at Object.onceWrapper (events.js:273:13)
          at Gunzip.emit (events.js:187:15)
      
      

      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,
          maximumEntries: 10,
          calendars: [
            {
              symbol: "calendar",
              url: "https://www.ojrsd.com//site/handlers/icalfeed.ashx?MIID=11"
            }
          ]
        }
      },
      

      Anyone else come across this issue?

        Hi Dommer,
        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.

            at IncomingMessage.emit (events.js:187:15)
        

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

          @Dommer said in Calendar issue with 2.7.1:

          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"}
          

          raw data from ical

          BEGIN:VEVENT
          UID:42271
          DTSTAMP:20190414T112505Z
          SUMMARY:District Closed
          CLASS:PUBLIC
          STATUS:CONFIRMED
          PRIORITY:0
          SEQUENCE:0

          DURATION:P1D
          LAST-MODIFIED:20180523T131717Z
          TRANSP:OPAQUE
          END:VEVENT

            @drfukc this is the same problem as for @Dommer …
            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

              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

              Starting MagicMirror: v2.7.1

              Whoops! There was an uncaught exception...
              { Error: listen EADDRINUSE 127.0.0.1:8080

                address: '127.0.0.1',
                port: 8080 }
              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
              
              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:
              PID TTY          TIME CMD

              1. Checking PM2 by ‘pm2 list’ gives me only one instance:

                @drfukc said in Calendar issue with 2.7.1:

                { 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

                  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):

                  Whoops! There was an uncaught exception...

                    address: '127.0.0.1',
                    port: 8081 }
                  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

                  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”

                      Thanks for your advise. After launching the mirror I do a pm2 list with the following result:

                      pi@raspberrypi:~/MagicMirror $ pm2 list
                      +-------------------------------------------------------+
                      ¦ Name        ¦ id ¦ mode ¦ status ¦ ? ¦ cpu ¦ memory   ¦
                      +-------------+----+------+--------+---+-----+----------¦
                      ¦ MagicMirror ¦ 0  ¦ fork ¦ online ¦ 0 ¦ 0%  ¦ 2.5 MB   ¦

                       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
                      [PM2] Applying action stopProcessId on app [0](ids: 0)
                      [PM2] [MagicMirror](0) ?
                      +------------------------------------------------------+
                      ¦ Name        ¦ id ¦ mode ¦ status  ¦ ? ¦ cpu ¦ memory ¦
                      +-------------+----+------+---------+---+-----+--------¦
                      ¦ MagicMirror ¦ 0  ¦ fork ¦ stopped ¦ 0 ¦ 0%  ¦ 0 B    ¦
                      +------------------------------------------------------+
                      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 &
                      [2] 1279

                      pi@raspberrypi:~/MagicMirror $

                      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
                      +------------------------------------------------------+
                      ¦ Name        ¦ id ¦ mode ¦ status  ¦ ? ¦ cpu ¦ memory ¦

                      ¦ MagicMirror ¦ 0  ¦ fork ¦ stopped ¦ 0 ¦ 0%  ¦ 0 B    ¦
                      +------------------------------------------------------+
                       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?
