RSVP missing from invite Mail Attachment.ics

[leymannx]

Owncloud on 1&1 Unlimited Plus Shared Hosting on Linux

$OC_Version = array(9,1,0,15);
$OC_VersionString = '9.1.0';

Nextcloud Calender App <version>1.4.0</version>

OSX 10.12 OSX Mail 10.0 (3226) OSX Calendar 9.0 (2155)

Steps to reproduce

1. Setup OC, activate calendar app, activate contacts app, allow Share API, create 2 new users with personal email address set, add them in their contacts respectively.
2. User 1 creates event in calendar, adds attendee which is user 2.
3. User 2 has OSX, has setup calendar and contacts from OC, now gets invite mail, but "Accept", "Decline", "Ignore" buttons missing, same in OSX calendar app.
4. User 2 checks Mail Attachment.ics and notices that RSVP=TRUE is missing, whereas everything else looks fine.
5. Editing Mail Attachment.ics and adding RSVP=TRUE manually and open it again makes OSX calendar work as expected, buttons to accept, decline, ignore are appearing and status changes when clicked.

   Expected behaviour

RSVP=TRUE in *.ics file to accept invite.

Actual behaviour

RSVP=TRUE missing in invite *.ics.

Can you reproduce the same behavior with Nextcloud?

[leymannx]

I'll try that. BRB

[leymannx]

Exactly the same.

Nextcloud

$OC_Version = array(9,1,0,16);
$OC_VersionString = '10.0';

Nextcloud Calendar App <version>1.4.0</version>

PS: Guess I'll switch to NC anyhow 👍

[georgehrke]

Okay, thx for checking. :)

I need to see if this is a bug in the calendar app or the Nextcloud server.
