That's a strange format.
Not only the \n but also the spaces in front of them.

Is this really correct?

[Bolli84]

Yes, it is an used format for booking into Reservations at hotels, restaurants, gamespace bookings over many simple websites.

This is just a very abbreviated form but shows all relevant content.

[the-djmaze]

Ok, this is a Nextcloud bug.
Nextcloud Calendar requires ATTENDEE and your file has none.
nextcloud/calendar#4684

But according to RFC 5545 section 3.6.1:

; The following are OPTIONAL, and MAY occur more than once.
attach / attendee / categories / comment /
contact / exdate / rstatus / related /
resources / rdate / x-prop / iana-prop

Yes your file is valid, problem is Nextcloud

Does snappymail recignize the calendar-file to be imported?

The calendar can be imported by nextcloud calendar directly quire easy. But it should be recognized first

[the-djmaze]

The calendar can be imported by nextcloud calendar directly quire easy.

How?

I only found the PUT command and that crashes the Calendar app.

[Bolli84]

With the PUT into the webdav calendar as well as ther direct IMPORT into the calendar by opening the Calendar and importing it with the lower left corner

[the-djmaze]

Ok, then they probably modify the ICS file to fit their needs.
I just PUT as-is.

I'm not going to modify ICS because then we are bound to Nextcloud Calendar quirks, updates, bugs, etc.

There should be a different way.

[Bolli84]

Just as I did with old rainloop. Only PUT it.

[the-djmaze]

@Bolli84 that's what the code does.
Exactly the same, so something else is going on.

Maybe line endings CRLF vs LF, maybe something else.

[the-djmaze]

I've tested and tested and tested.
The problem really is Nextcloud and i can't do anything about it.

When an .ics file contains ATTENDEE or ORGANIZER, Nextcloud Calendar 4.1.0 keeps crashing on me.

When i remove all ATTENDEE and ORGANIZER properties of the .ics, the import succeeds.

I even tried the import function of Nextcloud Calendar itself and it still keeps crashing, so it really has nothing to do with SnappyMail

[Bolli84]

My point is the following:

On many other calendars, the button: "Put in Calendar" appears in snappymail to include it. The given calendaritem does not show this in snappymail. It allows me to download it.

So, this is not even at the point to IMPORT it still for me.

[the-djmaze]

Admin -> Extensions -> Nextcloud cog wheel to enable

[Bolli84]

No, does not work.

Can I send you my calendar-mail i got for you to try?
