Whats wrong with this Calendar entry (nextcloud not loading)?

[DKX47]

Hi all,

I recently editet a calendar entry (I think i just moved it to another day). After doing that, the nextcloud calendar wasn’t loading in the web interface. The spinner animation did not stop, no entries were shown. I than deleted the entry via a connected Thunderbird and all went back to normal.

I’m just curious what was wrong with that entry, maybe someone has an Idea?

I am unclear how you produced this data in the first place. That’s not a valid .ical record.

You can validate this at iCalendar Validator

Thanks for the hint with iCalandar Validator

I copy/pasted this out of my ICS-Backup File so there was something missing in the end and at the beginning.

Putting together the pieces of the whole ICS file i get this
