ICS Formattting error

[luisakakpo]

Good morning!
I've spin up Calendar for a test ride and it looks very nice!

However we have an issue with the formatting of the ICS file when sending an event invitation.

My email provider (protonmail) flags it as an invalid invitation and does not integrate it within the calendar.
And when I check the .ics file with the icalendar validator (https://icalendar.org/validator.html) it confirms it is invalid with the following errors:

Errors

    Invalid TZID value or missing VTIMEZONE component (Europe/Paris) near line # 6Reference: 3.2.19. Time Zone Identifier
    Invalid TZID value or missing VTIMEZONE component (Europe/Paris) near line # 6Reference: 3.2.19. Time Zone Identifier

And here is the .ics

BEGIN:VCALENDAR

I've tried to contribute a solution but the codebase for ics formatting was a bit more complex than I expected (and now it seems I cannot access the repo at all?).

Would it be possible to look into it?

Thank you,
Luis

Hello @luisakakpo and welcome to the Cloudron forum
Thanks for reporting, we will look into it.

@luisakakpo If you log in to our gitlab, you should see the repo. It is currently 'Internal' (i.e visible only for logged in users). I have been trying to tackle these AI bots last few weeks and made most of the stuff Internal. I hope to resolve the situation in the coming weeks.

I have fixed the problem though and fixed another issue which the validator found.

Hi @girish,
That's amazing thank you for the quick fix!
I'll give it a quick spin

I get a 404 not found error when trying to access the repo at https://git.cloudron.io/apps/calendar.
Is that the correct place to access the repo?

I think that is because you are not in the Packaging group. I have added you now.
