NoMethodError

Hello,

When I try to feed a Google Calendar Private ICS URL, specifically for a TickTick calendar that syncs with my Google account, it throws an error claiming that event_data is null.

I will say, I inspected the ICS, and there are multiple records in the ICS that do not include the description field, which is what I am trying to match off of. However, some of them do have description fields.

When I test on another ICS file where all records have description fields, it succeeds.

Does ical-filter-proxy require / anticipate the description field to properly function?

Here's the traceback:

Let me know if you need any more details. The ICS contains sensitive information, but here are some safe records from it as an example. Again, this is straight from Google Calendar's ICS.
