Error fetching CalDav calendar - Found no components where exactly one is required #112454

Closed kamilszewczyk closed 3 weeks ago

The problem

I have set up a CalDav integration with calendar.zoho.eu service. Unfortunately it is intermitently failing to download some calendars that I set up. It sometimes work, but more often it throws: Unexpected error fetching CalDAV data: Found no components where exactly one is required. The same caldav server works perfectly fine on other caldav clients (like Thunderbird) + it DOES sometimes work in the HA integration.

Follow up question. The CalDav integration doc page indicates, that the events from caldav calendars are downloaded every 15 minutes, however this is not what I seem to experience. It looks like the events are synced every time the Calendar tab in HA is opened. Is that the correct behaviour?
