No events being shown: "invalid date-time value" #376

karloluiten · 2017-03-22T06:34:22Z

Steps to reproduce

Open my calendar ('Personal')
Wait for events to load
Spinner keeps spinnging, errors show in the console

Expected behaviour

Events should show up in my calendar ;)

Actual behaviour

UI loads, my 'contacts birthday' calendar loads fine, my 'Personal' calendar does not work. It DOES work on my android phone though(!), through CalDAV over DavDROID.
"Does not work" means the spinner keeps spinning and javascript log shows errors.

Suspicion

I think some event dates are broken and I want to blame my imported facebook birthdays, but I have no evidence of that.

The text was updated successfully, but these errors were encountered:

georgehrke · 2017-03-22T12:54:10Z

I see two bugs here:

the calendar itself should load fine even if some events are broken
the fb birthday fix doesn't kick in (https://github.com/nextcloud/calendar/blob/master/js/app/models/veventModel.js#L327)

karloluiten · 2017-03-22T13:56:57Z

Thanks for taking a look at this/tagging and commenting.

Is there anything I can do? Or do you have enough data? Thanks a lot.

georgehrke · 2017-03-22T13:58:06Z

I think I have enough data to fix this.
I'll look into this in the next couple of days and will get back to you when I need more information :)

karloluiten · 2017-04-05T11:00:48Z

Is there news? Let me know if I can help :)

georgehrke · 2017-04-05T22:02:35Z

Can you provide me sample ics please.
FB actually fixed their birthday calendar, so i can't use that.

karloluiten · 2017-04-06T10:52:48Z

What I did:
Get random error from console:

"Error: invalid date-time value: "2017-05-02T::"

Get response from REPORT request to https://nc.***.nl/remote.php/dav/calendars/***/personal/

Looked for the string "2017-05-02T::". No results (?). Then I looked for 20170502 and got 3 matching VEVENTS:

BEGIN:VEVENT

Is this what you were looking for?

georgehrke · 2017-04-07T21:52:09Z

Did you disable all other calendars and only try to load the broken one?

Looked for the string "2017-05-02T::". No results (?). Then I looked for 20170502 and got 3 matching VEVENTS:

😕

Can you please double check?
2017-05-02T:: has to come from somewhere.

Searching for T:: should be enough.

karloluiten · 2017-04-08T11:57:45Z

Created a test calendar, shows fine and I can add calendars
Disabled the test and "Contact birthdays" calendar
Reload, see the same error (it still seems to load the Contact birthdays" calendar, odd)
I get the "Response" tab from the REPORT request. ''No T:: in there'', which I find very odd.
I downloaded the 'personal' calendar (the broken one), searched the ics file, ''Also no T:: in there".
To be sure I also downloaded the other 2 calendars, no T:: there either.
I got the whole error list and kept my phone (which has a working calendar) next to it: it matches 1:1 to facebook birthdays on my calendar. Example:

BEGIN:VEVENT
DTSTART:20170502
SUMMARY:***'s birthday
RRULE:FREQ=YEARLY
DURATION:P1D
UID:b100000416765***@facebook.com
END:VEVENT

Are the events maybe being rewritten somewhere? I can't really explain it otherwise. Thanks a lot for your time though!

georgehrke · 2017-04-08T12:00:46Z

DTSTART:20170502

Ah, obviously 🙈
It's supposed to be DTSTART;VALUE=DATE:20170502, we can catch that error.

karloluiten · 2017-04-08T12:01:47Z

I see this code:

293       if (findTypes.indexOf(dateType) >= 0 && el.trim().substr(-3) === 'T::') { // is date without time
294         icsDate = el.replace(/[^0-9]/g, '');
295         ics = ics.replace(el, dateType + ';VALUE=DATE:' + icsDate);
296       }

That will not match the time-less thing I suppose :).

-edit- just see your post, think we got something :)

georgehrke · 2017-04-08T12:05:03Z

it's only applied when the ics data contains 'T::'. (https://github.com/nextcloud/calendar/blob/master/js/app/models/veventModel.js#L327)

we just need to add an extra rule if the length of the date is 8 but there is no VALUE=DATE

karloluiten · 2017-04-19T11:00:33Z

Is it hard to add a 8-length check to that veventModel.js? I tried editing on my personal server but js seems to be minified in some way...

pojntfx · 2021-05-27T09:49:47Z

I can confirm this issue still persists on 20.0.9; for example importing https://splan.hdm-stuttgart.de/splan/ical?lan=de&puid=20&type=config&lc=,oJ,m,Wqb,d,b,b,b,g&oex=false, my Uni's schedule, fails with:
