Describe the bug All of a sudden, my ics calendar isn't downloading. Google private calendar link in ical. So I have tried two versions of HA and three versions of this (5.0.2 5.0.3 & 5.0.4 beta). All will not download the calendar anymore and gives me the following error in the logs:

This error originated from a custom integration.

Turns out it was because someone added an event without any title. I think it relates to this issue https://github.com/franc6/ics_calendar/issues/125

Would it be possible, that instead of the whole parser not working & just throwing an error, that if the event was say blank, it said "Unknown" or similar and didn't stop the integration from not working?

I’m sorry, I should have replied earlier, but didn’t have the time to look up the previously reported issue. Really, I think the problem is in HA. Why not let users have calendar entries without a summary? Other calendars obviously allow it…

I’ve only gotten three opinions now on how to handle it, I think, and two of those were from the same person. :)

I need to do some testing still on what exactly is required, too. But so far, configurable might be the way to go, or perhaps the first X characters of the detail.

Thanks for the reply @franc6. When it wasn't working and I wasn't sure why, I tried this integration instead; https://github.com/tybritten/ical-sensor-homeassistant it handled the blank calendar entry by just saying "Unknown"

Either way, I agree it should allow it but I guess it ends up landing on you to do a work around. If possible, it would be appreciated...
