Q: Calendar returns 400 error

Hi all,

 

Since adding a rather large calendar, I get the following error in Calendars (previously iCal):

 

The request for account “iCloud” failed.

 

The server responded with

“400”

to operation CalDAVAddCalendarQueueableOperation.

 

Anyone any ideas to resolve this issue?

 

TIA,

Jasper.

    I solved my problem myself.

    When you don't have a local account you can't import a new calendar (.ics file) directly to iCloud.

    What you have to do is copy the web address (URL) of the .ics file and then subscribe to that URL in Calendar.

     

    Not sure if this is a bug or feature though

    Thank you this was helpful. What's considered a local account?

    Trianglejuice, thanks, but I also would like to know:

     

    what do you mean by local account?

    where to you find the URL in a .ics file?

     

    Thanks.

    Sorry, I meant a local calendar. You can't create any local calendars anymore in Calendar (previously iCal). It was a calendar that was "just" on your Mac and not synced to any service.

    See my answer above for the local account part.

    If you want to find the URL of an .ics file, you just have to select the .ics file in Finder, hit Cmd-I and voila!

    A Google Calendar subscription got stuck and even I deleted the subscription the message kept coming.

     

    I exported all my calendars to back-up, cancel my iCloud sync, turn it on again and import the calendars again from scratch. Now it works fine.

    I missed something in the explanation above: I deleted the contents of the folder [user] > Library* > Calendar

    *press alt and go to: Finder Menu > go to > Library

     

    The Mac Calendar creates the default calendars again, and you can restore the calendar backups

    Some days ago, I got exactly the same message.

    I wanted to create a new Google calendar subscription and I wanted to put it (maybe wrongly) in my iCloud list. The calendar never appeared in the side bar, but instead I got this message full of myth and magic.

     

    After hours of google'ing around I found a solution, which solved my problem:

    I closed iCal/Calendar. I opened my user library (press 'alt' and select 'Go to' --> Library in the menu bar) and took a look into the 'Calendars' folder were I just deleted the file 'Calendar Cache' and 'Calendar Cache~' (if there). Starting Calendar again, everything synced well again, no mean messages or anything. Then I imported the Google Cal via Preferences --> Mail, Contacts and Calendar. Worked without errors.

     

    Cheers.

    Thank you! The backup or export of my calendar archive, shutting down Calendar and deleting the Calendar cache files in the user/library and restarting Calendar and importing the backup solved a problem I have been gnashing my teeth about for quite some time. Who knew it would be so straightforward. I am using Calendar 8.0 on a Mac Air running OS X 10.11.1 - thanks again.
