google calendar not syncing old events, but tasks are okay

peefy

hi,

i (re)installed (install, delete, install again, etc) google calendar several times in vivaldi, and checked all the calendar settings several times, but google calendar won't sync.
Strange enough, I do see my tasks, and holiday calendars (.ics), but no regular calendar events.
The calendar logs are empty.
Any idea what is wrong? and how to fix?
Thank you!!

Hi, I use Google calendar since a while to get easier access on my Android devices.
Tasks are not working correctly, one user report but I don´t use tasks.
I have a second calendar from vivaldi.net enabled and all are in sync.
If I add a event on the Google calendar app on Android it sync on my desktop devices.
As usual you can only testing this in clean profile to exclude settings, extensions an broken profiles.

@mib2berlin thank you!
but the google calendar still does not sync.
it does not sync in a new profile,
and it does not sync with a browser reset

regular google email does work okay, but calendar not.

any ideas?

Hi, not really, what happen if you hit the test button in the calendar settings:

@mib2berlin I get the same:

connected to caldav. found 3 calendars

it says found 3 calendars, but under calendars I see 4 calendars:

my main calendar
official holidays public calendar A
official holidays public calendar B
my task list

calendars 2, 3, 4 do show up fine.
calendar 1 does not show anything.

so why it does not find the main calendar?

thanks!

@peefy
No idea, I poke in the fog.
There are some settings to check even it seams a dump question.

I am not sure why the calendar items are hidden but it work for me.
You can only test this in a clean profile to exclude settings, extensions or a broken profile.
Create one, close all tabs and enable email/calendar in vivaldi://settings/general/

If you don´t need it anymore you can delete it or use ot for further test situations.

Cheers, mib

@mib2berlin hi thanks for the info, but i already tested it all in new profiles, and even in a fresh vivaldi standalone installation.

I exported the main calendar to see what it contains, but the .ics export file seems empty!

I tested the google calendar (with Oauth) in microsoft windows calendar, and in microsoft windows calendar it works perfectly.

In vivaldi I see no normal events, only task events, even if i disabled sync for tasks in preferences panel.

@peefy
Hm, I am a bit out of ideas now, only a third party security software can block this for Vivaldi but not for the main stream applications.
For example I cant add mail accounts in Vivaldi but in Windows mail with a running Avast. No errors, no messages, it simply cant connect.
Do you use one by any chance?

Cheers, mib

@mib2berlin

I think we have to look here:
why caldav only finds 3 calendars instead of 4?

I checked https://www.google.com/calendar/syncselect but all calendars where checked there as well.

mib2berlin

@peefy
No idea, I hope one of the mail/calendar developer steps by on Monday.
Do you use one or not?

Cheers, mib

peefy

@mib2berlin no, I only have the native windows defender active

peefy

@mib2berlin Further testing reveals that when I add a NEW event in vivaldi or android, it gets synced,
BUT the older events are not synced (nor imported when i add the account, the account is empty after adding the calendar to vivaldi)

peefy

@mib2berlin As a workaround I wanted to import the export file from google calendar.

gcal exported an .ics file of 376kb
I tried to import it via the file menu in vivaldi, the dialog showed "0/693", I pressed ok, and went to see the calendar, but i got in the calendar status bar:

imported 0 of 0 (NaN%)

This is an important clue I think, if even the manual import didn't work.

One would think that the export process is faulty, but the syncing in windows calendar goes just fine, with no issues at al.

@peefy
Hi, I import my Google .ics, it is 179KB and import is working fine, Vivaldi 5.6.2867.46.
The calendar was empty as I import.
You can open the .ics in a text editor, the first lines of my one:

Can you check yours?

@mib2berlin
Did you get 4 files if you expand the .zip file?

peefy

@mib2berlin Hi,

I got only 1 .ics file when expanding the gcal .zip export file.

I got 2 files, one is the calendar and one is Contacts, thought you have four calendars so you get 4 files but I am not familiar with Google calendar properties.
We have to wait for a mail developer, maybe @gmg can look into.

Cheers, mib

peefy

@mib2berlin THANK YOU for all your help!
I have only 1 file, and no contacts, strange ...
The google tasks is a seperate calendar file, but it too, is not exported.

peefy

Hi @mib2berlin , @gmg :

I tested the .ics in https://icalendar.org/validator and it says:

Success! No errors found.

There were some warnings though:

Line length should not be longer than 75 characters near line # 46
Reference: RFC 5545 3.1. Content Lines
Line length should not be longer than 75 characters near line # 47
Reference: RFC 5545 3.1. Content Lines
Line length should not be longer than 75 characters near line # 48
Reference: RFC 5545 3.1. Content Lines

Any clues anyone, why .ics import does not work?

Hello @peefy

From your description here my guess would be that there is something in the iCalendar content for your main calendar that our parser chokes on. It is normal (From the point of view of how it is implemented now, but not how we'd like to see this from a usability POV.) that the number of calendars for google account excludes the task list(s), so I think 3 found is expected for your account.

If you try to import the .ics file do you get any error in logs, either those found in the calendar button on the status bar (lower left corner of browser window by default) or in developer console. If you do not know how to access those I can guide you.

We really need to improve our error reporting to aid with debugging problems like this.
