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 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 Request.emit (events.js:182:13) at Gunzip.<anonymous> (/home/pi/MagicMirror/node_modules/request/request.js:1079:12) 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. 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 Request.emit (events.js:182:13) at IncomingMessage.<anonymous> (/home/pi/MagicMirror/node_modules/request/request.js:1079:12) at Object.onceWrapper (events.js:273:13) 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

@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, lineif (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.jsI 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 uncommentI rather believe my issue has something to do with to many Electron instances that kill several moduls.
Maybe you have an idea for this:- I boot up my raspberry 3b
- Execute ‘ps -a’ to check the running processes
- ‘ps -a’ returns ‘ps’ as the only running processes
- launching the mirror: ‘npm start &’
- the console tells me uncaught exception since EADDRINUSE is already in use:

Maybe no internet connection? If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues- 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:

{ 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

@sdetweil
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 Aktive Internetverbindungen (Nur Server) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:8081 0.0.0.0:* LISTEN 836/electron.js tcp6 0 0 :::21 :::* LISTEN 418/vsftpd tcp6 0 0 ::1:3350 :::* LISTEN 446/xrdp-sesman tcp6 0 0 :::3389 :::* LISTEN 461/xrdp udp 0 0 0.0.0.0:5353 0.0.0.0:* 318/avahi-daemon: r udp 0 0 0.0.0.0:68 0.0.0.0:* 348/dhcpcd udp 0 0 0.0.0.0:47216 0.0.0.0:* 318/avahi-daemon: r udp6 0 0 :::5353 :::* 318/avahi-daemon: r udp6 0 0 :::34261 :::* 318/avahi-daemon: rI 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 ... Connecting socket for: updatenotification Connecting socket for: calendar Starting node helper for: calendar Connecting socket for: newsfeed Starting module: newsfeed Sockets connected & modules started ... Whoops! There was an uncaught exception... { Error: listen EADDRINUSE 127.0.0.1:8081 at Server.setupListenHandle [as _listen2] (net.js:1330:14) at listenInCluster (net.js:1378:12) at GetAddrInfoReqWrap.doListen [as callback] (net.js:1492:7) at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:55:10) errno: 'EADDRINUSE', code: 'EADDRINUSE', syscall: 'listen', 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 Launching application.While the mirror is running I execute again sudo netstat -lnptu and get:
pi@raspberrypi:~/MagicMirror $ sudo netstat -lnptu Aktive Internetverbindungen (Nur Server) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:8081 0.0.0.0:* LISTEN 888/electron.js tcp6 0 0 :::21 :::* LISTEN 435/vsftpd tcp6 0 0 ::1:3350 :::* LISTEN 450/xrdp-sesman tcp6 0 0 :::3389 :::* LISTEN 465/xrdp udp 0 0 0.0.0.0:42644 0.0.0.0:* 318/avahi-daemon: r udp 0 0 0.0.0.0:5353 0.0.0.0:* 318/avahi-daemon: r udp 0 0 0.0.0.0:68 0.0.0.0:* 354/dhcpcd udp6 0 0 :::42148 :::* 318/avahi-daemon: r udp6 0 0 :::5353 :::* 318/avahi-daemon: rThis 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”

@drfukc is mirror starting on boot with PM2?
go to console and do
pm2 list
is something, get its name and pm2 stop name -
Thanks for your advise. After launching the mirror I do a pm2 list with the following result:

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 [1] Fertig npm start pi@raspberrypi:~/MagicMirror $ > magicmirror@2.7.1 start /home/pi/MagicMirror > sh run-start.sh Starting MagicMirror: v2.7.1 Loading config ...

What is wrong here? -
@drfukc that calendar,

this one contains thru 2019
