"Import failed to save." Calendar.app on macOS Catalina (With example)

[dewey]

Hey there,

I'm trying to generate an ics file and import it into Calendar.app of macOS Catalina. I'm getting the following error for the given file:

The ics file I'm trying to import is:

BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//Arran Ubels//Golang ICS library
METHOD:REQUEST
BEGIN:VEVENT
UID:456
CREATED:20200610T181852Z

If I remove one of the events so that there's only one in there it works:

BEGIN:VCALENDAR

I'm running out of ideas what could cause that, it's a valid file according to: https://icalendar.org/validator.html#results

Do you have any idea what could happen there?

Thanks!

Just found that if I remove: METHOD:REQUEST it works. Maybe "Request" doesn't work if there are multiple VEVENT in the VCALENDAR.

Any chance you can play around with it and figure out if I have implemented it wrong?

[dewey]

I'll see if I can spend some time on it but I can't promise anything. It was just a quick script where I used it.

[arran4]

@dewey No problem. Let me know if you get time to look at it. I think this library needs some love IMHO.

Yep! And THANK YOU for this comment, you made my week by getting me unstuck on an apple calendar .ics import bug with like, no documentation 🙏

@starspace1 Is this something the library should be picking up? (Or is putting in the wrong location?) (If only I could get more time to work on the library.)

Ohh, nice find with the RFC! Good to know it's not just an obscure bug but actually the standard. Glad my stabbing in the dark was actually helpful to anyone else 😄

[arran4]

@dewey Did you need anything from me on this or can I close the issue?

[dewey]

I think you can close it. I'm not using it at the moment but at least we documented the behavior in this issue for future search engine users 😀

[arran4]

Oh okay. Wil you use it in the future?

[dewey]

Hey, unsure. My project is now built in Rails instead of Go so that's why I don't really have a use case right now. If I need a Go lib in the future I know where to look though :)
